JPUyers 1977 Journal NARL, Barrow, Alaska 27 May arrived yesterday evening (2330) with Dick Erickson + Lynne Stengel aboard Great Northern Airlines, an electra flying in lieu of Wien Service. Wien Air Alaska is currently being struck by its pilots, adding one additional hassle to the difficulties of getting north this spring. Temperature on arrival in 20's, foggy with misty snow and 60 cold wind. No birds apparent by the airport, only hawks hyperboreus seen en route to NARL The next morning I spent most of my time politicking, mostly w/ Gary Hanners--now the assistant Director for Science. Some good news emerged--as NARL feels that they will not be asking increased charges for users, at least until October. Birdwin came a Spizella arborea walking back from breakfast, Snow Buntings singing cheerily from telephone poles. No Uropica calcaris. 1500 took a truck out to POW-matin, then into town + finally out to IBD. Few birds, much snow. But melt-off proceeding quickly with 35° warmer air and sun. 14 polygons exposed in many places including Broken area, Beach ridge, Pow- martin, the drum area, etc. With today's warming we seem to have received a significant influx today. Longspurs definitely moving in, a bevy of Golden Plovers.-Puddy for writing. See Daily List. GRIO 2,3; TRANS 2,4,5 28 May 1000 went out with Dick after seeing Lynne off to Nicate River. We went to transects 5, and 4 to sample. See transect account. Only amazing things seen-- flies, large house fly like insects sitting cold on the tundra surface. Obviously alive, in fact a few were buzzing about. Weather: temps in high 20's to low 30's. light N wind shifting to west. Overcoat at first but fog thinning as morning

SP Myeus 1977 Journal GRIDS 1,2,3,4, Barrow, Alaska 30 May (cont?) To Grids 3+4 for more snow work. The character of the day had changed partially, as the cloud cover left. But still windy and below freezing. Some p[illegible] displaying and at least 1 apparent pair by Voth Creek. As in the a.m. much Golden Plover activity. But the coup was a berry (4) of Buff-breasted Sandpipers displaying on GRIDS. All apparent. All 4 grids were largely snow covered, with, very few units (<10) having a snow cover under 90%. Came in at 1600. By 1800 it began to RAIN! did so for ~1/2 hr, never a heavy cloud burst but much more than the usual drizzle. The arctic trip to keep us on our toes. At Kasook, Meade River, North Slope Borough, Alaska Meade River - alfin! Flew in this p.m. at ~1730 after a pleasant but somewhat foggy 30 min jaunt via Cessna from NRL. Just as we came upon the Meade the aerial extent of snow cover decreased rapidly, both around the Glafo and down away from the river on ridges. Other- wise the tundra was 90-100% snow covered. Thin in many places it is considerable ice, & with some ridges up to 100% free. Birdlife it is far advanced from Barrow: melan[illegible]s hooting everywhere w/ quick acting as if they came off nests; one C. lap. with a complete nest cup. All spp. displaying to the hill, save Yellow Wagtail which Lynne Skrgeel says come in this a.m. Pteromigian are absurd, sounding a bit like pheasants mixed with a Mormyridae. Willow Pt. molt for advanced compared to Rock (of which there are few. Lynne + I walked from ~1930 to 2400 south toward (15,34) [one map of Meade w/ grid system] along largely cleared ridges. Caribou present, their grazing sign obvious in scuffed places. & Lagopus. perched on top of mounds everywhere, occasionally indulging in flight display. & Plovidis of both spp butterfly fighting continuously. But the most remarkable thing to me is the density of

Journal Atkasook, Meade River, N.Slope Borough, Alaska 31 May C. melanotus in all habitats save exposed lichen ridges. They are especially prominent in low center polygons. 1 June Walked from 10 am to 1930 w/ Lynne Stengel, going from camp (11,40) east [see map] to (28,42), then south along the river to (19,36) and finally back to camp. A glorious sunny day through the morning and into mid afternoon, with temps ~ 40°. High clouds from ~ 1430 to ~ 1830, and then sunny for the remainder. A light NE wind. We traversed a range of habitats, beginning with the bluffs by the river- camp spotted w/ Salix spp. The trees, although giants by Barrow standards, are rarely over 1m high, scrubby, and we get lacking leaves. Catkins from one sp. (S. lanata) are woolly spread beneath the branches. A few Zoro. Krusophyta, tranthus sp., & Motacilla flava are all using these habitats. All are in various stages of display. Walking east we continued along the river bluff until reaching (15,39), an area which Lynne calls Ground Squirrel Pt. from the abundance of Spermophilus. Traveling due east from there we entered a region of low wet funda still largely covered of snow but populated by melanotus, porilla, and mauri. The low center polygons in this area and particularly to the south from our path are more similar to Barrow habitats along transect 3 than many other LCP areas at Meade. Here the minimum elevation is higher + has a drier vegetation type on top than the low Barrow LCP rims. Vertical relief in these can regularly be over 30cm. But in this area they are lower, up to 20 cm or so, and the vegetation is similar to flat appearing or higher Barrow LCP rims. Catenas are often Caren - Eriophorum s., as at Barrow. This zone strictly as far as X=24, and also has a series of Caren - Archophila lined lakes. The easternmost ones are far advanced in melt and were decorated by many (???) Ochtholizania (>20) Ph. foliarius (see spp spacent). Immediately upon passing beyond the last of the lakes we had a new vegetation + landform type; the terrain becomes

J.P. Myers 1976 Journal At Kasook, Meade River, N. Slope Borough, Alaska 1 June (cont'd) Much weaker polygonization, with shallow incuding trosses <20 cm, and an overall rolling slope. Veg. upland tundra, Carex, Salix pulchra, Racomitrium dry tundra ridges of higher areas of Aletriona + Dryas antigridelin. Pluvialis squatarola country. Sitting on an abandoned squirrel mound caused by Elymus, Artemisia and others we watched a mob of Ph. fulicatus 89 pounced on another over a CP (all up accent). Shortly afterwards we contended cow + immediately found a Tryngites lek (one up accent). Up to 15 birds on a dry ridge, veg. deciglits up to 15 cm (old grasse) - much more substantial veg. than I've ever find a Tryngites in. We watched for ~1 hr + then continued west, passing quickly into band downs w/ occasional Salix lanata - Elymus stands and even less frequent wet ponds lined w/ Carex or Eriophorum. Dunes are ~200 m wide; we saw 2 birds in them, a pair of P. dominica beside one of the marsh areas. We hit the river near (28,39) and walked across. It is less than 1 m deep at this point, and the shores are cobbled. A large willow-lined ravine lay on the other side - we climbed up for the view and were surprised to see how retarded melt-off is on the NE side. After a moment's reflection it seemed apparent that the difficult phenology was due to prevailing winds depositing dust + sand from the eroding river banks onto the snow downwind, which lies to the SW. One ERIMINE moving back forth within a matrix of eroded ground squirrel molar at the top of the bank. At ~1530 we began walking SW around the loop, + then cut inland at (27,39) but were stopped immediately after guffing through the sand dunes by more Tryngites activity; apparently the likely extent for ~750 m WSW including map units (25,41) -> (26,39). Hagoopus nutans in the dune nearby. After watching for another hour we again began to trek back, heading W along the river to (19,36). Part of the river edge line are terraced, alternating between large stands of Salix glauca (~40 cm high) with mallow and a wet Carex-Eriophorum augustifolium

After leaving the river we passed through a gorgeous mosaic of ponds, low low center polygons. Rims are moundy, up to 30-40 cm, narrow, and covered w/ the bedum so Vaccinium, Salix glauca association so common to manic sites here. Centers largely Carex-Eriophorum russellii Much bird activity compared to the dryer ridges, w/ displaying emlanetes, puisilla, mauri, fulicarius, a few Ph. lobatus flying by. Definitely related to Barrow habitats saw the ericacious nature of rim vegetation.

JP Phye 1977 Journal Atkaook, Meade River, N.Slone Borough, Alaska 1 June (cont'd) Carex marsh C. melanotus Limnodromus Pancerculus sandwichensis Carex - Arctophila not melted yet Flocks of several spp are moving through the area. Most pronounced are Pomarine Jacques - during early evening we saw several (4-5) large flocks numbering up to 25 pomarines/flock. All are moving unswervingly to NE. Anser albifrons and Branta acuta also migrating. The most obvious other migrant still moving in number are Pectorals - regularly throughout the day small flocks numbering up to 35 birds fly by in a NE direction. Other birds are cruising about w/o quite so consistent a vector - dunlin are moving large local distances, Ruddy fulicaeus, Longspurs. 2 June Worked all afternoon on transects, not returning to camp until 2245. Both LS and I were barely able to put together 4 words in a coherent sequence that night. Such is life on the tundra. We put in Transects 1-5, located to the West and SW from camp (see approximate location on map). Brief descriptions: TRAN① begins in sloping low center polygons immediately west of camp. After ~200 m it enters a stream gully bordered by Salix pulchra/Carex and follows the stream up to where the stream drains from a lake. It then cuts north into more LCP area, then again W out into upland tundra. Most of the transect is either LCP or stream side willows. TRAN② begins on a lichen ridge, following that for 150 m before running in to upland tundra + mixed polygons w/ Carex and low S. pulchra/ Betula. It then cuts saw through upland tundra, crosses a path of lichen tundra, and then continues thorough upland, making one more crook to avoid a large lake. TRAN③ is straight (!!), beginning in string bogs of Carex and then cutting across a mosaic of low wet tundra until ~ Slat 12, where it goes on to upland tundra. TRAN④ is also straight, heading east across a small patch of lichen tundra, a large low Carex marsh, and then out onto upland tundra and finally LCP's. TRAN⑤ follows a lichen ridge, w/ much crookedness.

JP Myers 1977 Journal Atkasook, Mcade River, North Slope Borough, Alaska 3 June 1100 to 2000 laying transects, today out in the Eastern Loop (see map). We began by readjusting (5), extending it further south along the ridge and cutting off some ugly meandering by Squirrel Pt. (16,23). Then we put in 6-10, going along the route indicated on the map. Weather was brisk, in the high 30's with a steady 20 mph ENE wind. But a brilliant sun made it tolerable. Only 1 new sp seen today, a Sabine's gull's flying over to the east. This evening we were not out as late as in past nights, and that perhaps as a result the earlier migration of jaegers and pied-billed gulls was not so apparent. I had meant to comment on its progression in yesterday's journal to re-emphasize (after 1 June) how obvious it is. Well over 100 Pomarine Jaegers went by the evening of 2 June, and 210 flocks of 6-15 g pied-billeds also, flying low over the tundra, headed east. The jaegers are obviously cutting across the base of Pt Barrow, heading overland. But the Pects? - where are they coming from? Why are they so low? Transect descriptions: (6) cuts across low Carex marsh, cary strings, and then into a lower tier polygon system with Salix pulchra, Carex, etc on the rims. (7) begins in a Salix lanata streamside terrace, goes through Carex marsh, up over a snowbank onto squirrel mounds and then along the bluff in a LCP system. (8) Starts in Flat polygons (land mixed) and then enters lichen tundra and wet lichen Heath. Midway through it jogs north into more wet-lichen tundra and then upland Carex-Salix pulchra Racomitrium tundra with much Bog. (9) goes through dry high country. (10) Begins in a wet Carex marsh, types up over a ridge of upland tundra and LCP, and then enters a gorgeous expanse of low LCP's. 4 June Another (the last) transect placing day, this time 9. We began mid morning and continued till 1700. Then flew a 2 hr stretch helping RATE invaders (5 people arrived). We returned to #8 transect 10 to lay a breeding bird plot (1 km x 250 m), using from 10 as a frame. The day was pleasant till ~2000 when a fog blew over. Temperature over in 40's, a

JPMyers 1974 Journal At Kasook, Mcode River, N. Slope Borough, Alaska 4 June (Cont'd) steady 15mph wind, and mostly solid sun. During the last 3 days melt off has cleared most of the tundra: from >75% overall (with bare ridges) to <10% overall. Runoff considerable, but the river has yet to melt. Large lakes still are frozen - e.g. #728, but with substantially cleared margins or at least ponding along the edges. Melting of other ponds quite inconsistent - some are melted cutally w/ even an inch or so of muck on the bottom, compared to others we still walk across. Immediate siped lakes show similar variation. But there is enough clear water so that purlais, oldsquaw, and white-front guise have separated + passed. Many pursuits act as if they have seen already (ice forced me out with an egg yesterday). Oldsquaw are not on nests yet. King Eider began flying around their evening (3 separate pairs), 2 separate groups of Arctic Loons, and fairly continuous displaying by Gavia adamsii. Our transects were unusually easy to put in, and STRAIGHT! #1 - beginning in the upland tundra it quickly plunged down a ridge, runs through 200m of Carex marsh, string bogs, and Arctophila ponds, and then back into higher ground, LCP's and finally Elymus sward down. #2 again starts on a ridge, gets into an short patch of lichen tundra, and then passes through a long stretch of upland LCP. It ends by plunging off a ridge onto a lake basin bordered by Carex marsh. #3 is largely in Carex Marsh and Arctophila lake margin, before running up into a flat polygon area. #4 Begins in a low area w/ string Carex and wounds, except the quickly enters upland tundra and low center polygons, and heads down a fenced LCP ridge, and then ends in string bogs beside a lake. See Maps. Grid © was placed around 710 (See map) w/ the transect lines serving to define y=1 of a 250m x 1000m (25ha) census plot. Most of it is LCP, but it varies from string bogs to a slight ridge with HCP's. Certain nutting species: Anas acuta, Clangula hyemalis, Ecto Pluvialis squatarola, Calidris melanotos, C. maritima, Calpica, Cypriella, Linnodromus s., Lagopus l., Calcaris lap., Panniculus sandvichensis. Also possible - Gavia arctica, Gavia stellata, Stercorarius pom, para, longi. How does the habitat differ here from Borrow? : 1) w/ River (Slopes of there is considerably more relief). 2) Sand from river bed causes under variation in

J Pilipus 1977 Journal Atkasook, Illede River, N. Slope Borough, Alaska 4 June (ent/8) soil condition, this makes for deficient vegetation. Particularly evident in river basin and along bluff where there are sanddunes (e.g. w/ Elymus & Salix glauca) And also w/ more subtle effects on the vegetation in Palagonia (the far end of the loop [25,40] region). This vegetation differs from other upland tundra, lacking Eriophorum vaginatum, instead having a cover of wet lichen, Carex, Poa (thin), Carriope. The Poa (thin but up to 10cm high) gives the place a ragged look. Occasionally patches of Salix pulchra stands also. ③ Many more woody species, with much more substance to the plants. Not only are there 4 spp. of Salix, as well as a Betula, but in some places the forest is extensive: up to 5 meter high and a fluchet, spread over a ha. or more. Thickets on river terraces, but also in low wet areas along streams or near lake edges, especially where the lake is drained by a stream. Betula is widespread too, growing on LCP rims, as well streamside. ④ Barrow lacks the extensive development of LCP's that are here — here they are much better defined, with high (30cm) trims and broad shallow crotins. The contrast between rim + center vegetation is probably stronger here than at Barrow. ⑤ Here Arctophila fulva ponds — most pools which would be A.f. (lined) at Barrow are instead Carex aquatilis. The Carex grows deeper here, and the A.f. pool if does exist, is deeper also. This may have to do with the longer and warmer growing season here. I'll bet A.f. is displaced by Carex into deeper water here to a point where growing seasons are comparable to the A.f. season at Barrow. My theory is that its distribution here is in ponds which melt later and are deeper. 5 June 1100-1700 ran transects 1-4,14 while ALS did 5,11,12,13. Day began w/ rain + cold (dropped below 32°C in early morning). By 1400 clearing so that by 1800 (ALS + I went out to finish pulling in transect 13, breeding bird plot 1800-2000) it was absolutely gorgeous — no wind, no clouds, warm. A fog bank held persistently on the horizon, embracing (shrouding?) Barrow otherwise in sto pall. The transects went reasonably well, averaging 147 species as they should. I must admit: however that Eriophorum vaginatum tussocks make life

JPMyers 1977 Journal Atkasook, Meade River, N. Slope Borough, Alaska 5 June (Cont'd) and cursing more difficult than Barrow tundra. One remarkable overall observation is impression in the patchy distribution of birds along the transect, even w/o habitat patches. Some areas have a lot of birds, others don't. A significant fraction of this can be attributed to habitat distributions, with fewer birds in upland tundra. But even in that habitat the birds are clumped. I will be interested to see how intensity of use through the season varies in different units. MELT-OFF largely complete, with snow cover extensive only in snowbanks. Last nights + this am's rain certainly hurried the process. A few flying insects are about, diptera, hymenoptera, moths, and there are also Colembola-like on pond surfaces. A few aquatic inverts beginning to be visible in the water. The following annotated spp list summarizes bird observations here during 31 May -> 5 June. Gavia adamsii - 1st seen 1 June flying over. Regular 2 June. Displaying in air + calling by 4 June. 5 June paired on large lake at (9,28) Gavia arctica - 1st seen 4 June flying by in flock of 4. Seen 5 June flying over Anser albifrons - flocks seen 31 May and through to 5 June. Some obviously passed on 4 June. Branta bernicla Branta nigricans - 2 flocks totaling 25 seen 1 and 5 June Anas acuta - flocks and pairs seen 31 May. Nid-w/1 egg found 3 June. Obvious early & common by 5 June but small flocks still apparent. common. Anas bahyryphus - 1st seen 2 June (18°). Single pair seen 3 and 5 June.

Some ♂♂ fighting. ♂ displays constantly (flying up + sailing down w/ tail spread, calling). By 3 June convinced that 9♀ have nests but unable to locate any. ♂ stays very close to 9♀, acts as decoy - in most habitats. Common Lagopus mutus. evident 31 May but uncommon compared to L. lagopus restricts to sand dunes, drier lower cliffs + ridges. ♂ not begun molt. 9♀ will along ♂ displaying 31 May - 5 June. common Ploceidin dominica displaying actively 31 May. much chasing. paired by that date. underused habitat use but seems prefers higher ground, I think. Heavy overlap w/ P. squavola (see below). By 5 June pairs behaving as if nest. common P. squavola - intense display activity 31 May - 5 June. much chasing, butterfly flight. Strong ant distraction display 5 June. (rowing motion by ♂). Defensively prefers higher ridges + bluffs but also seen in low areas (maybe only those w/ ridges nearby?). common Arctaria interpres - displaying + chasing actively by 31 May near camp and a few other sites. But not seen 5 June, uncommon 4 June. they may have moved on. RARE (<10/day) 6 June 1 seen in 4th probable ant distraction on loopy ridge (next to chicken function) Calidris melanotus - ♂ shooting when I stepped off plane 31 May. see sparent. 9♀ giving bug-off display to ♂ by 3 June. But 9♂ flocks flying by through evening of 9 June. Next found evening 4 June. Widespread in habitat but more concentrated in low areas. Carex strings, extensive LCP's. ♂♂ also on ridges. ABUNDANT C. mauri - displaying actively evening of 31 May. Continuing throughout through 5 June. some aggressive interactions w/ C. pusilla. ♂ neat cup displays, intensive choice. habitat largely restricted to wet tundra + nearby ridge particularly near lakes, pools and lakes. ♂♂ tool about over considerable distances, but display focus well defined (i.e. patchy). I cannot discern habitat difference from C. pusilla save that many pusilla are also in drier ridges than mauri. common

Journal Atkasook, Meade River, N. Slope Borough, Alaska 5 June (Cont'd) C. pusilla - displaying actively 31 May. Pre-cup displays 1 June, 1 nest cup found 1 June. Distractin displays 2 June and thereafter. Habitat widespread from low wet sedge marshes to dry lichen tundra. May use both where they co-occur, and be restricted to lakeside mosaic w/ bluffs where both are present. But why? a common bird Tryngite subruficollis - lek activity 1 June (found by h.s.30 May) w/ active 8" - see op accent: individuals seen elsewhere also (3 on 2 separate occasions). Lek habitat is Carex-Salix poltura upland tundra merging w/ wet lichen tundra. Limnodromus scolopaceus - displaying actively 31 May. Adults strolling as if w/ nest by 3 June, but still tooling about in two gaggles of 5-8 birds flying 100-200 m overhead, singing on 5 June. Also pairs seen flying long distances - straight flights from the Tuna I first detected them until after they disappeared even on 5 June. Habitat largely low+ wet or LCP paths on ridges. Most frequently observed in Carex string. Calidris alpina - displaying actively 31 May but not common except around air strip near camp. Birds obviously still moving until 3 June (same as Limnodromus). On 5 June transect sample detected many more than I had expected. Also found several obviously w/ nests (but found no nests). Habitat tends toward upland sites although some do occur in lowlands. Upland polygonized ridges especially mixed polygons with mostly flat centers appear to be preferred. Habitat separation w/ inclemation more apparent here than at Barrow: alpina is an upland bird. Phalaropus fulicarius - inconspicuous 31 May but a few individuals that might. Significant influx 1-3 June w/ 98 appearing first (see spacer). Moved into large melted ponds originally, then spread to lake margins and Carex marshes as these cleared. By 3 June conspicuous pairing (MAATI 1 June lots of 9 organisms centered around 8"" (see spacer). Wet cup found 5 June. 8" sunplanting

Nests typically built under Salix pulchra or clump of Eriophorum vaginatum. Plectrophenax niveus - perhaps as many as 4 pairs in area around camp using bluff + buildings including main shaft.

But at 1400 they indicated that it was unlikely a plane would come in, so I immediately set off to sample transects 6-10. LS is having foot problems. Ran transects 1530-2030. Got back to River breakup began in earnest while I was sampling camp at 2100 + plane appeared at 2130. Drove in NARL by 2230. Yeah! Transects were very productive at Meade - see summary. Flight back to NARL was fascinating as lighting was superb. All of the tundra is melted around Meade but as you go north the % snow cover increases until by Barrow up to 50% still under. Birds 1+2 are in sharp contrast w/ surrounding habitat because they are almost 100% clear tonight (apparently heavy melt-off today w/ sun, Fide Erickson). Talking w/ Erickson is disabring because his comments indicate a piss poor prenanotes year, and very few fulicarius. NARL, Barrow, AK 7 June went outside 0'm. w/ Erickson + D. Shuford to grids 1+2. I frankly didn't believe their comments about how few birds there were. But out in the guide I found only 3 8" melanotos (max) with only 1 heard in 2 hours. Bitter cold (30-32° w) ice on surface, strong

JPMYAS 1977 Journal VARL, Barrow, Alaska 7 June (CONTD) NE wind + low wet overcast misty clouds. Oh for the sun of Meade! Calanus is still building meat cups, but C. pusilla + C. alpina appear to be well dispersed + probably w/meat. The melanotos scene is frightening. So few, doing NADA! Perhaps it is early but the ducks are here in abundance, particularly Anas acuta. Few delicharias. Spoke w/ Rileka this afternoon as he calmed me down (ein neur) saying it was still early. I decided to return to Meade because more field time was essential there. Then at Barrow night now given effect of scare. Ranunculus nivalis blooming Atkasak, Meade River, N. Slope Borough Alaska 1900-2300 returned to MR via Arctic Guide Airtary. NATEL unable to drum up flight. And Meade is bitterly cold, fog + wind. Unlike the friendly place I left. River up enormously (201). Big ice jam in front of camp backing it up + spreading over lowlands 8 June Quite a day of Barrow weather - ice on ponds, low fog and NE winds at dawn My fervor for fieldwork was quelled abruptly after a brief tender sojourn. Spent the morning completing field notes, then in the afternoon (through 2000) got to the breeding bird survey to do censuses. See breeding bird census account for results. Overall impression of the grid is one of reduced activity by displaying birds, particularly Eumelanotos. This is generally true across the tundra. In fact today & saw a melanotos or w/ reduced pectoral deposits. Hooting record infrequently. Also apparent is the reduced flow of migrants through the area, save for Caria arctica. However many species are still quite active: pusilla, mauri, alpina, limnodromus, Pluvialis dominica + quadricolor, Calanus. 9 June 0800-1400 outain the loop, first in Patagonia looking for Fringilla, then back to the census grid from 1130 to 1400. Census totals combined w/ yesterday's and w/ Lynne Stenzel's in census account: Weather again less than desirable (but clearing by 1130). Strong NE wind. The buffy siskin was disappointingly - max of 2 - see sparent.

JPMyers 1977 Journal Atkasook, McCade River, N-Slope Borough, Alaska 10 June off at 0700 to sample transect 5, 11-14. Weather today (VHT 1400) was the most pleasant I've ever experienced on the N-Slope - 50's, no wind. No mosquitoes yet I was able to spend from 1000 on in a t-shirt. Remarkable. From the last day's field work I have to suspect we have passed the peak of activity for many shorebirds: Pectorals are much less active, and are almost unresponsive and not receptive to DT. Dunlin air invariably spooked you with a surreptitious note + skull off away. Semipalmes are still displaying, and so are waders although not anywhere nearly as often as a week ago. The only species still obviously in the throes of their sexual expression are phalaropes and waterfowl. Yellow-billed Loons were having a violent fight on Bingo Lake - grebbing each other by the neck and whacking into incredible force, and all over 300 m (and more) away. Phalaropes are copulating. Glaucaous-quills are laying. And the ducks are quacking - all are paired, seeking out certain pond + swale, dropping eggs between sedge tussocks. Tundra has dried perceptibly, in a season lawn center polygons - the center vegetation is emerging along the periphery. Ancrum blooming, Pedicularis lancii in its early woolly stage NARC, Barrow, Alaska 12 June tracking E. melanotus during a.m. (0900-1300). Tapa recorder malfunctioned after 14 min of work so the entire morning was a bust. Dawn was clear + warm but at 0700 a heavy fog moved over, and did not disappear until 1130. melanotus very sparse. SRIDY evening (1800-2100) went to GRIDS 3+4 to truck. Both had E. melanotus active but in each density was obviously low. So I went to 4 because it lacks any appreciable relief, being all low LCP and ponds. Tracking was successful from 1840-2023. See melanotus spp accent, tracking record for 6/12/77-8. Species seen en route to the grids added 2 to the daily list, Calidris canutus and Calidris fuscicollis. The density of displaying C. bairdii along gasbar ridge is truly remarkable, with displaying individuals lining the sides. They have arrived within the last five days according to Dick and Dave. TUNDRA PHENOLOGY: Ranunculus niveus blooming in selected sites on GRIDS 1 and 2. Melt off largely complete even on GRID 4, where ~5% or less remains snow covered.

SP Myers 1977 Journal NARL, Barrow, Alaska 12 June (cont) Longer blotchy of snow remain along prolated ridge sites and in creek bottoms. Run-off from the melt has created but flow is still appreciable flow. Tundra ponds at their fullest. 13 June tracked 8 melanoto on GRID 4. see mel sp accent. 14 June tracked 8 melanoto on GRID 4. see mel sp accent *. Also tracked 9 fulicarius. Dave Shuford has become quite adept at hooping them so we now have a banded pop. P. bairdii especially prominent now, particularly along Gasline ridge, displaying continuously. ASIDE → why should there be so much individual variation in their distances at which birds get off nests. HYP: an optimizing problem between advantages of getting off early (lower predation) vs advantages of staying on longer (less thermal stress). May also result from different predator strategies. What other factors could be involved (more later)? 15 June d sampled transect 3 a.m., then dld tracked 9 fulicarius in a.m. sp.m. Not terribly nice day. 34° windy. Dave Shuford is doing quite well at catching 9 P. fulicarius. 8 melanoto now appearing on GRID 4 after a day in which several flocks were seen flying W or NE. This appears to be comparable to the movement last year, although today's easterly wind may be keeping them down or making them less conspicuous. 16 June more tracking on GRID 4. As of this evening Dave has captured 19 fulicarius, 17♀ and 2♂. Wind today made activities truly miserable, with 34° almost all day and a low wet fog moving in by moon. The strong easterly winds of the last few days have created an incredible feat on the sea ice — there is now a lead several hundred meters wide curtain (km of shore [probably ~300 m from shore]). We had known that there was very little fast ice formed by the mild winter this past season. Now that is abundantly confirmed, because even with howling gales normally would not suffice to open up a lead so close to shore, especially one the dimensions of that now sticking off NARL. By town it comes much closer to shore. Dick and Dave scanned it for birds and saw only Glaucon Corrals and Black Guillemots.

JPM Myers 1977 Journal NARL, Barrow, Alaska 16 June (con't) And how is it? - melt-off is now complete, save a few snow-filled creeks. Run-off is largely over, with Both Creek clearly subsiding. But the tundra remains wet, covered in many places up to 95% by melt-off water, particularly in latitudinal belt (6810 4), i.e. poorly drained Carex-Eriophorum roscosum meadow + low centric polygon. Ranunculus nivalis continues to sprout yellow blooms amid the dark brown of standing death. Pedicularis canadensis is now at its woolly best, showing signs of pink blossoms along Garcinia Ridge and in fact a few flowering individuals can be seen. Salix pulchra has pussy-willow-like catkins heavy with yellow pollen. And in several places the greening of the tundra has begun - crowns of Eriophorum and Dryas are gaining color, being most evident in areas where winter lemming activity was concentrated. Lemmings? - I've seen 2 lemmings so far, one on Garlin Ridge, the other on 6810 1. Cropping is heavy but in a few patches. But nothing compared to the previous 2 years. This lemming crashed during the winter. Of course this has import for the birds: no breeding peregrine jaegers, no snowy owls. In fact there don't even appear to be settled parasitic jaegers. Two standard developments of note. (1) Numbers of Q pectoralis is up markedly, and its display activity has also risen. This includes the previously barren 6810 1 area. (2) Baird sandpipers are having a very good year, displaying with extraordinary conspicuousness along Garcinia Ridge, and even out into the treacherous 3 region. Westerns and C. mauri and C. fuscicollis are also more obvious this year. 17 June another day of tracking. Wind resumed, sun stayed out, making work more pleasant than the goats. yesterday. We now have 24 banded birds on or around the grid (in theory). But the frequency of sighting these birds suggests there actually are many more out than one might expect. Fewer than 50% of the birds we observe are banded. This suggests that quite a large # of birds move in and out of the area. Further, we see only a small proportion of the banded birds. This suggests that birds move freely in and out of our focus of activity - something already hinted at by the tracking data. 18 June ditto.

SP Myeus 1977 Journal NARL, Barrow, Ak 19 June tracked 8 melacones and 8 fulicaris today, from ~0900 to 1540. A long cold day in the tundra, weather varying between chilly and cold, fog or sun, ~34° rising to 40 but with a constant northerly breeze. The preboreal scene looked up today, as I worked 4♂ with decent and reasonably small territories. Not strenuously active compared to last year but hopping enough to keep me busy and physically warm. Even though the ♂ were active I found precious few ♀ in acc: in fact only one popped up off the grid as I worked. Mean ± there were probably no more than that, but ♂ were 87% moving through. The fulicaris scene is calming down considerably, with many fewer using the grid now, and most of those being either coupled ♀♂ or ♂♂ in units. However the bird I tracked (B:6) laid her first egg today. -a rope-cone-lately. See Heteroxodus brevipy account 20 June very frustratingly today out on 6410 4. Yesterday I had tracked melacones along the eastern and southern eastern + southern edges, feeding for cooperation. Today I tried the Northern half + had a hell of a time finding ♂, much less any ♀ being territorial. As a matter of fact there are at least 2 areas where non-territorial ♂ are daily as they please without risk of being supplanted. Activity along E+S centuries culminated. Weather today was Barrow at its variable best: 34° at 0700, rising to 38° during snow, fog, a NE wind, splashed with a fog flicker of sunshine when a break in the thin overcast let a few rays through. Not obvious 21 June Produce Bay, North Slope, Alaska Flew to Produce (Deadhorse Airport) today on the Wien jet, arriving 1215. Found rented truck immediately + set off looking for place to stay (VE construction - [illegible]) Apparently I drove past the place 3 or 4 times before actually finding it. The Produce horizon is very dis-orienting, filled as it is with innumerable drilling rigs, indistinguishable construction camps, and an curved flatness that exceeds even that of Barrow. Today's low clouds and intermittent rain only compound the problem. Once I found the place, checked in at

Journal Privilege Bay, North Slope, Alaska 21 June I began to reconnoitre, with my first stop being the ARCO base camp to call on Angus Gavin, resident Mr. Nahina, duck counter + wildlife surveyor for the oil companies. His report: early year that froze up again. Ducks galore, particularly A. acuta and even a few A. platyrhynchos. He also told me they had yearly flights of Limnodromus griseus as well as scolopaceus! According to Gavin both Belderson + Spectacled Eider nest within the oil fields commonly, as do Branta bernicla m., B. canadensis, Aythya marila, the A. platyrhynchos this year (no evidence yet for nesting) are unusual, and probably relate to the incredibly high W. Slope dabbler density of this year [J. Bertonek of Alaska D. Fish + Game reports his aerial transects up a minimum of 100%]. Gavin obviously has his heart in ducks, and may not be the best source for shorebird info. He did comment on lower than normal Ph. lobatus and Ph. fulicarius densities, as well as an absence of Tryngites in a usual lurking spot south of Angel Pingo. Pectoral sandpipers and Semipalmated Sandpipers are in good number, he says. After finishing up Gavin (1930) I cut off in the truck for a broad regional survey, driving first out to the West Dock area and then all the way to the Kup River. This road system via some ways is fantastic, allowing, for example, me to see more acreage of tundra, than in 3 hrs driving that I had in 2 entire years at Barrow on foot. Judging from obvious bleeding Gavinachia, Somateria spectabilis, and other large waterfowl the roads have been adapted to — perhaps not by these species — the larger ones which may still be breeding in lower density or with reduced success — but probably by most shorebirds. My warning is simple — if the large birds appear to be breeding in number than the smaller ones probably are even more so, being more tolerant of human activity. But one very real concern that I have is for the possibility of an altered melt-off regime. All these roads and ground + dust will cause the snow to melt several weeks early, changing the thermal regime, exposing the vegetation to colder temperatures and light earlier than expected, and also making run-off early. This may directly affect the migration, or it may affect the invertebrates — i.e. the sandpiper prey. Anyway, I cruised about until

Journal Proudho Bay, N. Slope, Alaska 21 June 1815. On the whole the habitat here appears more uniform over smaller areas than that at Barrow, but in to these may be more types here. The most familiar to me are found out by the wet dock, along the N.W edge of the bay - a good mosaic of mixed polygons and ponds w/ C. melonotus, C. alpina, C. pusilla, Ph. fulicarius - i.e. the Barrow hard core. Of these C. melonotus are the most conspicuous - as you might expect because of the for behavior. But C. pusilla pop up whenever you stop, and in wet areas Ph. fulicarius are quit regular. No where, however, have I been taken by a real abundance of shorebirds. Even longspurs rather infrequent 22 June today set 3-0.5 km transects in a miserably persistent rain. temp ~36°. NW wind 100% low clouds. rain from ~1030 on until my part when I quit at ~1830. This is worse than Barrow weather (though I accept that Barrow is suffering similarly - the thought that fly too are encroached is in a perverse way consoling). My transects emphasize low wet tundra today - low center polygons and low hummocks grading into somewhat higher land on Tran 1 (see map for locations). T2 is entirely low center polygons and marshes. Three CP's are nowhere nearly as well formed as those at Meadow River - they lack the well defined rim system with a deeply contrasting center. Nevertheless the rims are perceptibly above the center and their occupation is more manic. T1 also crosses over a slight sloping ridge and then passes in to some high hummocky areas (lakes) with a fair mass of dry rim veg. with low troughs and centers - but the physical array is much less regular than that at Meadow River. I also traversed some streamside habitat - Dryas rubrafolia, Saxifraga oppositifolia with strong seed boil activity on a steeply sloping bank. Although the habitat was extensive - 20 m wide + as long as I walked along the stream (500 m) found only one bird - a soaked Lagopus mutus f. A nearby pingo across which T3 passed & observed a hunting Sturnornis longicaudus (actually in the adjacent upland tundra) and a displaying C. alpina (appeared to be nesting in adjacent upland tundra), and a displaying P. quadrata as it supplanted a P. dominica. 23 June more constantly rain this morning, soaking through my "rain" gear. What fun. - temp 36° a good NW wind chopping along blowing the rain that came up at 0430. I am still frying

J.P. Myers 1977 Journal Providence Bay, N. Slope, Alaska 24 June carh. quite a day - out into the field at 0620, back at VE by 1715. Forgot lunch, but that made little difference as there wouldn't have been time anyway. Sampled all transects save 8 & 9 (West Dock). The difference in bird densities between Upland tundra and anything else was painfully evident, particularly on transect 4 & 5 where I recorded no shorebirds. See transect summaries. Weather not as bad as last few days - with a steady moist misted of rain (but the mist is thick enough to render binoculars a frosted mess) unless it's Temp ~38°. Steady NW wind. Began clearing ~1700. Typical timing. 25 June 0600 out to transect 8,9, near the West Dock (Barrow analog). Sampled each twice this am, going out and then returning. A caribou proceeded me as I worked out, moving along the transect line, running back to investigate me, then clambering on. Not the exact coordinates animal. Saw several buffle in route, displaying 87° (see appendix). An arctic fox worked over some littoral tundra by the end of the dock, harassing a B. bernicula. Weather improved considerably - light NW wind, occasional calm. Temp in high 30's. High clouds, no mist. After sampling both the West Dock transects I drove out to the East Dock to check out the sand dune regime: few birds in if any in the dunes proper, although the place appeared replete w/ Spermophilus. There are large expanses of sedge carried sand (Consolidated dune) that harbor C. pinilla (a few), Calcaris lap (a few) and both phalaropes wherever there is a large pool. Near 'Surf-Cote Camp' and by the river in sedge marshes there appeared to be large numbers of waterfowl. But in general this area is bleak compared to other local sites. With today's good weather there was an emergence of dioptrum - looks like a large chronomid - which Phalaropes (both spp), Arctic terns, Sabine's + Glorious gulls are keying in on a roadside pond. A feeding frenzy. Stopped on way back from sand dunes to talk with Angus Gavin about waterfowl habitat. He tells me the following: GEESE - Taster ellipsores prefer large lake margins in low areas, and can nest quite densely but in separate pairs. Branta canadensis also nest in low wet areas but do not require as large a body of water - they will nest on small islands or ponds. Branta bernicula nest in colonies in a

JPMyers 1977 Journal Prudhoe Bay, N. Slope, Alaska 25 June (cont'd) few places, particularly littoral areas, on several lake margins (e.g.) Eurf Cote camp, and especially in Barrenland places beside lake margins. All three species of geese are common Ducks - Somateria spectabilis, Anas acuta + Clangula hyemalis are all common species nesting C.h. most common in extensive lowlands. He (Gavin) detects no strong habitat separation. Loons - only common species is Gavia arctica - it is everywhere when lake or pond exceed 0.5 ha in size. p.m. 1800-1900 went to west side of oil field to sample transects (3), (10), (11). Went with Steve Johnson - one of Wayne Hansen's EROT employees who is studying musk oxen around the VE camp. Most impressive detailed evening over the number of tryngites about, including 19 on a musk (see appendix), and 58% recorded on transects. Arctic fox working lake margin, presumably for bird nests. Arctic foxes, by the way, are everywhere here this summer- rarely do I spend 4 hours on the tundra w/o seeing one looping by. No lemmings save in a few local sites where there is sign of some weasel activity (Barrow analog, VE camp area). The foxes are eating something else, probably bird eggs judging from Les Eberhard high musk predation ratio recorded by Johnson. Hansen's people tell me there was a serious rabid outbreak this past winter in the foxes, but Arctic foxes were recorded every far south - beyond the Brooks range - during the winter, and that fleas are apparently central (Her Killing) => all sign of a crashing fox population says Eberhard. 26 June out at 0600 to tran (10), (11) region to photograph Tryngite and Stenocercus longicaudus weather still improving, with the roads already spewing a bit of dust, light NW winds, high clouds with sun occasionally breaking through. The traffic area incredibly cooperative, stopping returning to the musk repeatedly and lay 8" away. The long-tailed jacqu even circulated my hand. Left Prudhoe Bay at 1230 on Wien flight to Fairbanks (80°) and then to Barrow at 1800. Foggy + cold. Below I list summary observations on all species seen at Prudhoe. Gavia arctica - common breeder on larger ponds and lakes. Noto on margin or on islands, distributed generally throughout oil field.

Gavin says they nest on lake + pond margins, using smaller bodies of water than Anser albifrons Branta bernicla hutchinsii - common, seen every day in flocks particularly toward West Dock. appear to be more concentrated in littoral marshes, but Gavin may dispute that. Nesting in a colony near Surf Cove Camp. Anser albifrons - common lowland nester, dispersed in tundra parks (but some flocks also apparent). Distributed throughout but seen less frequently by Service City Anas platyrhynchos - 2 PPs seen on 2 separate occasions in same place by Deadhorse Anas acuta - common, breeding this year in large numbers in lowland habitat.

Less Common than P. dominica, pair regularly other upland sites + particularly near ridge 1 & also seen along VE camp. 7" flight display on 26 June. Anseria interpres - uncommon, a few heard flying over, seen chasing jaegers. Calidris melanotos - common lowland sandpiper in all lowland tundra (except southern sand dunes + dunes). Ventures scarcely into upland tundra complex (see Webber/Walker vegetation types today's journal) where P. pectoralis lat. absent from upland tundra scours stretch. 7" actively displaying. 98 nests [illegible] C. bairdii - although the 1st pipers saw in Prudhoe this trip it is uncommon, occuring coastally inland in littoral (see journal 24 June) and nesting on pingos and probably along river ridges. Displaying actively on Buffy Pingo. C. alpina - common upland sandpiper, occurring occasionally into lowlands but not in great number, even where lowlands are polygonized. Recorded regularly on all upland transects. 1 not found by Buffy pingo; 3E24 June. Almost all birds moulting primaries. Very little display activity. Although an upland bird it appears to avoid the extreme upland barren tundra used by C. bairdii - i.e. not on snow bents or barren tundra. C. pusilla - most common sandpiper, generally distributed in both lowlands + uplands, but crossing uplands (I think) only when cut by Palmer streams - i.e. it does not occur on vast expanses of uniform upland tundra. Many nests, all W/4E. Little active display, but a lot of alarm calling. No sign of hatched chicks. C. mauri - one seen in Puccinella marsh by west dock 22 June.

J P Myers 1976 Journal Prudhoe Bay, W. Slope, Alaska 26 June (cont'd) Sterna paradisaea - seen regularly in low numbers foraging in wetlands. No sign of breeders. Nyctea scandiaca - seen twice near West Dock. → Acanthinip - heard flying overhead on 2 occasions, both times near Buffy Pingo. Calcarius lapponicus - abundant, widespread through most habitats, apparently limited only by the need for a dry nesting site. Sometimes I wonder if even that is necessary. OB still singing, but not regularly. A few flocking by 88. → Mots monitored by Steve Johnson near VE began hatching 21 June. Preying nutria obvious throughout my stay. I stumbled over at least 10 neat all with 4+ young. Suffering tremendous fox predation (see Johnson). Plectrophenax nivalis - blessedly limited to local sites around camps. Very restricted, not seen otherwise. Corvus corax - 1 individual seen on 3 separate occasions. Well that's it. Nothing unusual, just good, clean birds at Prudhoe. [illegible] I have appended vegetation description to today's journal, taken from work by D.S. Walker + P.J. Webster, INSTAAR. My transect units are all described in rough + qualitative terms using W+W's major Prudhoe vegetation classes. In general my impression is that habitat separation is clearer here than at Barrow, perhaps in part due to the more better defined separation between upland tundra and lowland areas. The finer scale of habitat interdigitation which pervades Barrow does not rule the Prudhoe regime. Instead there are a few large areas varying greatly in overall composition (this is an exaggerated simplification, but the trend is there).

SPMyers 1977 Journal NARL, Barrow, Alaska 30 June 4:00 p.m. walked 6 of town to Nunavet Bay, after driving as far as we could along the road going SE from the airport. Path took us successively [illegible] until hitting the slopes of the bay's upper reaches, and we then followed the bay along its mouth slope to within 400 m of mouth into Chukchi Sea. A gorgeous day of sunshine, light wind, and 40° temperatures. Most of the habitat we traversed was comparable to that found within our transect/grid area, but near the bay it developed extensive uplands - successively sloping leads into the bay - covered with tundra not unlike unit (8,1) of T6. Vegetation is essentially the same, same that Dryas integrifolia is common, and a few Salix reticulata are scattered about. But the real difference is the extent of the uplands, with the sloping creek banks occupying many ha. of continuous land. Above the rim of the banks the tundra turned to generic polygonized ridge vegetation similar to unit (18,1) of T7 - Poa, Salix polaris. Well drained troughs. Bird life was reduced in density in most of the upland areas we traversed, especially on the sloping banks where only 2 species were detected, Baird and Buff- breasted Sandpiper (1 of each) in the adjacent polygonized uplands. C. pusilla, Calyptra, and Plovielin dominica appeared, but only the 1st of these was "numerous" and then specifically in our location near the edge of the sloping bank. Some pusilla were seen flying between upland polygonized areas down to the water's edge on the bay. We saw no pusilla before reaching the zone adjacent to the edge, even though some of the habitat we traversed was good mixed pond + polygon. This reaffirms Frank's contention that pusilla depend upon this sort of juxtaposition of habitat types. Gobs of Emeletus and P. fulviviridis moved through the lowland Carex marshes. 1 July Transects today: I ran 6-10 while Dave Shufford sampled 1-5. Weather 33° at 0600 rising to 41° by 1430 when we returned. Fog, NE wind, clearing by 1100 to a sunny, cloudy day. The tundra is drying, ponds receding, flowers emerging. Found blooming Potentilla today and one Papaver in flower. Birds are moving through. Large flocks of Plectropterus mixed with Black Phalarope and a few dunlin were wheeling over the tundra - up to 410 birds in a flock. Gooline Bridge was teeming w/ birds: 28 Pectorals, 17 Dunlin in 10 ha.

JPMyeus 1977 Journal Barrow, Alaska 1 July (contd) A fox was working part of the transect, and appeared to successfully get someone's egg or young. (judging from its behavior). I am somewhat surprised by the # of flocking darwins evident already this year - birds that obviously are no longer breeding. According to Kay Everett, the storm which rained on Prudhoe for two days while I was there also hit the foothills with 4 inches of snow at Toolik Lake. Hansen's people at Franklin Bluff reported 100% mortality for Calcarius during that storm. So now we have a large Dulin moving through, and also non-breeding Q melanota. Are their unusual numbers a result of the storm? 2 July walked out to end of TIO taking ItzD data from 0730-1130. Then until 1400 scanned for nest on GRID 1. Weather began well, with 33° and a moderate E wind dropping to a light wind, all with 100% sun. But the wind shifted to a northeasterly direction and the temp fell perceptibly, perhaps because it also increased. Anyway, returning to the lab saw a pair of Aythya affinis - Scap with definite bump to profile and white speculum fading quickly on the shoulder primary coverts. Dave Shuford, who has much more experience of Aythya spp than I, got excellent view of the birds. He went out later with a scope + reported he will clean of the usual A. marila marking. There were also 3 Polysticta 9Q there, and there also was a flock of Polysticta 9Q out near Duck Camp. Unusual territory that may relate to strange movements by other birds - i.e. a massive breeding failure. GRID 1 - last year's GRID 2 3 July 0430-1245 censused GRID 1. Weather shitty: 33°, snow, sleet, moderate N wind picking up through morning 100% low clouds, fog at exact clearing up rising wind until ultimately sunny.

J.P. Myers 1977 Journal GRID 1, Barrow, AK 3 July (cont'd) Activity varied across species, but the theme was: "life harasses the human". C. pusilla were especially pernicious, and I saw one set of clicks. One C. alpina nest was hatching. As Dave S. and Dick E. have reported, melanotos and fulicaus activity is quite low this year here: no 3P on the grid of either species. 2 8T melanotos passing through, but several incubating 8T fulicaus, with 5 of their nesting (I think) on or off the grid. Calcanius were also a real trial, and my estimate of Calcanius number is off the mark probably. It is next to impossible to count them at this time of the year. Means 6-10 5 July Light rain from 0400 to 0600, but clearing there abouts. Strong E winds, reaching 20 knots. Censused Trans3,6-10 beginning 0930, ending 1540. A thoroughly cold day with temperatures in 30's, reaching ~40 after staying at a classic 38°. Distribution of birds has changed during last several days, perhaps related to significant cold (frozen morning/ some ice). Could not happen at worse time for birds, probably, because most duck/bird meets are hatching in a rush now. The chicks are out in the cold. Insect activity very low. I see adult tipulids crawling about in low number, and many of the ponds are writhing with emerged chironomid adults, but with this severe cold continuing perhaps their availability must be depressed. Today the distribution of Calcanius were remarkably different from just 4 days ago. On that transect day they were largely in upland areas, with very few in low wet edge marsh. Today it was just the opposite, and most of them were obviously with chicks. What gives? Are dleulin moving down this year? It is very dry, more so than last year. Pond depths decreased by over 10cm in a 14 day period ending 1 July. So if we assume that it is a real trend, and not some temporary aberrancy, I see 2 possible explanations: 1) that they are seeking damper foraging conditions for physical/invertebrate reasons (i.e. moving to a region similar in dampness to where they go each year) or 2) responding facultatively to the absence of melanotos and going into what is normally melanotos habitat. Pectorals, as I imply they, are quite sparse. I encountered 3 8P today which behaved as if they had 600s. 3 8P on ~50 ha. of transect. Trans 3 and 10 are largely barren, contrasting strongly with my experience of previous year.

JPMyers 1977 JOURNAL Barrow, Alaska 6 July ¿Que. pasa? The tropics arrive at Barrow. 38° at 0800, with a Cliff Swallow flying abide. Then through the morning the temperature rose to 50°, with a light breeze from W then S then E (growing) by late p.m. No clouds. I actually censused 6 and 1 ufo gloves, no hat, and a short-sleeved shirt. Uh heard of!! But no bird popped unexpectedly out of the woodwork to populate a deaperovati grid, so the swallow was a false omen. Yes, the grid totals were low: Anadara acuta 1000-1245 Pluvialis dominica ♀ 18 C. melaonotus ♂ 15 ← well that's not terribly low! ♀ 2 — that is C. alpina 9 C. bairdii 3 C. moui 1 C. pusilla 7 Ph. fulicularius ♀ 2 Passerculus Calcaris lapponicus ♂ 1 ♀ 8 ♂ 2 ♀ 0 Plectrophenax nivalis ♂ 3 7 July stayed in most of the day. Stenzel came up from Minds, Sliford went down. 8 July sampled all transects with purpose of repeating tomorrow and 10.5 am to get an estimate of short term variability. byrne did T6→T10 while I did T1→T5. Day was clear except for an hour around 1300 when the fog rolled in, only to clear abruptly by 1330. Moderate E wind, temp 34° rising to 40°. Generally pleasant. Bird abundance fairly good (see Transect accounts), and rare but the habitat scene is rather different from the last transect sample (7-05-77) when I had been impressed by Dunlin activity in the lowlands, especially along T3. Today they weren't there. How likely is a daily rhythm in foraging, such that one habitat is used during one period while another is at other times — that could be confounding. Certainly possible for species using the littoral zone — e.g. pusilla.

JPLayers 1977 Journal Parrow Alaska 9 July sampled transects today as part of continuing look at short term variation in transect use. It is obviously enormous, with large fluctuation in distribution of different species over the transects. Not clear that pattern of habitat use changes, but density of a given species -e.g. Melaunotos, recorded on a particular transect does. Await tomorrow's results for a fuller examination of the patterns. Weather may play a key role, though perhaps not. Today's was clear - strong E wind, high clouds, temp at 0700 = 38°P. Rising to 40° by 1500. => One astounding difference which has developed this year may be to enter the state of the sea. For the last 5 days there has been open water off shore; today it is open as far as I can see, with only scattered floes spotting the seascape. 10 July Yesterday's east wind has increased to ~30 mph, making cruising downright difficult. We therefore bagged field operation for the day. Spent ~0.5 hrs looking out to sea. Rissa tridactyla moving by regularly, as well as Somateria spectabilis and Chiongula hyemalis. Curiously the Chiongula are all moving NE toward the Beaufort. Must ask Duvicky what the significance of that is or indeed whether he is aware of it. 11 July temp 38° at 0600, 38° at 1400. Wind moderates to 20 mph through day as we crossed the transects. # of Melaunotos (and ? for that matter) impressive - see SP account. The results of this criterion set of samples taken 8, 9 and 11 July are interesting: (1) totals did not vary inordinately, although 9 July was depressed in overall density compared to the other two days (see T summairis) (2) A hot spot one day was not necessarily one the next, with a few exception (see Melaunotos sp account). In fact true totals contain a transect over days varied appreciably. Habitat distribution of dunlin and pectorals fluctuated somewhat, especially if the cursors on 5 July are examined also. Hypothesis: each transect passes through areas frequented by a loose association of individuals which, now freed from nest sites, move about in the general area. On one day I pick up one of these localized groups, on another day I find another. Thus there appears to be changing distribution when in fact there are not. I'm not sure I like the implications for my sampling procedure. This warrants a closer look, both at the data and at the birds. Peregrine falcon today heard hawking a Plectrophenax and

Wind has been oppressively consistent their last 5 days, and with the sun out continuously el tundra is reaching a parched state almost comparable to August of last year. If this continues it will be far drier here than I've seen it. 12 July 0740-0940 censused grid 2 (=1976/63). Temp 38° constant. wind strong, building to 20 knots from E. Bad enough to force me to quit before censusing grid 1, which I will do tomorrow. The flock of divalii using the lower left part of the grid is forming again, as it has for the past 2 years. I first began to notice an accumulation there 8 July when running T5. But at that time it seemed largely to be mobbing broody adults, flying in to harass me.

JPMyers 1977 Journal Barrow, Alaska 13 July (con't) The gull results from 1 to 2 are remarkably similar - consistent even. They reflect typical conditions for several species in mid to late brooding period. alpina + pusilla are both protective, mobbing from afar in several cases (with recently hatched pusilla being the worst offenders. I saw alpina chicks on 2 separate occasions this o.m., both sets far from fledging. Non-broody alpina are also about, as I noted in yesterday's Journal. It appears that the lower reaches of ORID 1 are being used again this year, although the birds today were nearer the lowland interface or G-1 than was typical last year. melanoto are flocking, with some differences apparent this year, things about which I have commented previously, in particular the absence (complete) of broody p's and the lower # of p's in flocks w/879. South Meadow Lake 14 July 1500-1530 at S Window hole to collect 9 melanoto for gonad condition. Large flock of melanoto, mostly of hat w/ 49 mixed in in them today (all appear), as they have been for the last several. All are feeding within 10 m of the lake shore, most in fact are within 30 cm, defending tiny territories at the edge. They are on the downwind side, feeding in the zone lapped by waves and spray. Wind is quite strong today, still NE 45 to 60 knots. Clear skies 38°. Oh for some calm and foggy weather! Lynne Stingle went to the point today, looking and reports high numbers of Rissa, Xema, and Larus hyperboreus foraging all along the spit. Up to 150 Phalaropus fulicarius also present. IPEWS 1-5 15 July 0740 → 1320 fighting the wind again, sampling troutsell. Admittedly it has decreased, making work more enjoyable and efficient. Temp 32° at dawn, 100% fog, mud & wind. By 0830 cleaning until by 0900 stark naked skies with a building wind. 38° when I came in. Birds again seem to have abandoned higher areas, with most in low wetlands or mosaics of ponds and polygon. C. alpina is definitely congregating into flocks now, as has been suggested during the last several days. C. melanoto may be more clumped in dispersion also. They certainly were not as apparent in the uplands.

JPMjews 1977 Journal Burrow Alaska 15 July (cont'd) Pluvialis dominica now in moulting and occurring in scattered flocks, using habitat similar to years past, i.e. upland meadows, gently sloping creek banks, etc. Decidedly upland in haunts. Nesting birds still linger on in a few places. But the milestones for the day were feeding juveniles C.pusilla and C.bairdii. It happens every year. Pectorals still tutored by S.Weedow lake (see opacent) but Ph.fulicarius not in exactly the same site feeding on what must be the same object. 16 July 0730-1100 on fundra by Coroline Ridge w/ Bonnie Bowens, scouting the area for Dicrostonyx; at least she desires for karyotypic work. We found much lemming sign, most of it obviously from this past winter's pop. The pile of tents was green, certainly fresh. But otherwise there was very little to indicate current lemming activity. The first fog for many days (except yesterday's brief episode) grazed due to 10-15 m. 33° temp brought out the cold, especially with a brisk wind.

J P Ulysses 1977 Journal Prudhoe Bay, N. Slope, Alaska 18 July 1200pm landed in Deadhorse Airport after 2hr ride on Lahr super DC3 from NAKL. Immediately appeared at Avis + NAWA Corp to establish ourselves. Then went to see Steve Jones + Wayne Hansen at VE - met hostily by Hansen, probably the reason in feeling kendroid. After Talking with them briefly we circuit + checked in w/ Angus Gavin, ARCO. But before that I should mention Jones's prediction rate figures - 65% of shorebird + palaearctic meets on his 250 acre plot taken by predators, primarily fox. Angus Gavin reports 90% lies for cirlons on his transects. Amazing fox year. Trip out to Old Dace after Gavin, largely car bonding. The tundra is barren, remarkably so. We found few shorebirds save a large concentration (100+) of tredy, most E. pusilla (up to 80) feeding on a gravel parking lot at the end of the West Dock road. Other spp present: C. alpina, Arenaria interpres - 80+, Calidris lapponica, A. pusilla, juvenile. All appear to be eating dipterans - mosquitoes, blown by the wind onto the gravel and trapped in its crevices. Occur at west dock in a conglomerate of wind-driven flocks with small circles + patches of open water scattered throughout. Many (several hundred) Changula flying on the water. 10+ Sterna paradisaea hovering along the dock. Milvus spp apparent but unidentifiable to species off in the Changula flock. 19 July 2 long walks today - one out NW beyond Buffy Pingo, the 2nd from Dock #1 ENE to the Sag Delta. Both w/ Dave Shuford. 0800-11:30 out by buffalo pingo - classic Burrow weather inflow fly lifting + dropping around us repeatedly. Easterly wind. Temp high 30's. We traversed a series of habitats including drying LCP, stream bank, low wet Carox sedge, + upland fennel. The only hot spot for birds was where the stream, coursing between 3m banks for most of the distance we covered, suddenly broke out into the lowland Carox marsh. At the mouth was a flock of alpina (10+), one broody C. himantopus, 2 juveniles pusilla, and many Calidris (better actually most dense along stream banks). A pair of Stercorarius longicaudus appeared settled locally, which is the area I had found a nest last June. Along the ridge where we walked Shuford + I found several small groups of Phoenicurus dominicus, typically at the crest of the ridge. One BROODY CALIDRIS BAIRDII. We were forced to return when Shuford decided to swim across a tundra pond (deeper than his hipboots). In the afternoon we went out toward the Sag delta, after a brief foray across the Sag River

J.P. Myers 1977 Journal Prudhoe Bay, N. Slope, Alaska 19 July Bridge toward Drill site #9. Large herd of caribou (mostly 80-50+ animals) adjacent to road. The Sag River basin where we crossed was devoid of birds + uninviting, a mass of gravel worked over by man + river. Also largely barren with the sand dunes between docks #1 and the Sag River Delta. Beautiful flowers (yet to be identified) but who birds. We passed over a large - 100m stretch of wet Carex aquatilis, Eriophorum russeolum, E. angustifolium low center polygon with many few birds. Only by the margin of a large lake where there any foraging shorebirds - 5 melanotos ?, ~10 Arenaria, several (5-10) xema), a broody Phalaropus lobatus ? , a Ph. foliarius ?. In the dunes we saw almost no birds. Did spook up 8 Pluvialis dominica but they took flight (if they indeed were on the ground) before we saw them. A flock of melanotos passed over calling mixed flock of Somateria, mostly speckled but probably molligani and 1 possible fischii. Out in the ocean flew some rafts of Changuia, a few Aythya (87 manitu plus one possible 9 affinis). Also birds looking like possibly Albatita Melanitta. But poor visual visibility of most of the ducks prevented positive ID. Spernophilus cat composite flowers. 20 July walked ~3 mi SW from S end of Big Lake, near Trans Hand 5, after leaving car at 0800, returning 1400. Much of route was incredibly devoid of bird life, but several pockets of activity were apparent. Weather 40-45°F, 100% clear w/ a low fog hanging off to the North. Light wind from NE growing through morning but never above 15mph. Temperature + wind remained low enough to keep even the horrendous mosquitoes down; although occasionally they rose to the occasion of our visit; particularly before 1100. Habitat: largely upland tundra mixed w/ frost boil habitat. (Climbed 2 pingos, also wandered about in midst of a nice lake system with...a mosaic of water bodies ranging from 50 to 200 m diameter (or long axis). It was in this complex of water + low tundra that we saw almost all the birds seen during the morning: geese (A.a.), tider, and all shorebirds: P. Squat, P.

Journal Brudhoe Bay, Alaska 20 July (Cont'd) a few broody Phyllocarvus plus a small group (3) evidently not broody. Essentially our trip was who birds - even Calcanius - for the first 2-5 hours as we trudged over upland tussock tundra, and past an occasional small pond or low polygon area. In a few places Golden Flowers or Black Bellies made their presence known. One flight of melanotis - ~20 birds moved E. We climbed a pinga - [illegible] flowering Dryas (past peak), Astragalus umbellifer, Papaver Macouni, a few flowering Oxymatry quinculent Oxypolis. Several Calcanius foraged around this pinga. As we sat on the pinga a herd of 4 q Rangifer plus ~20 q moved by; the q had one young with them and they kept going past us rapidly. The qst moved along and in fact seemed somewhat curious. Antlers on qst quite large but still velvety, foraging on Salix in the low center polygon centers. From the pinga to the SW we were able to see an extensive mosaic of ponds + lakes with thin isthmuses connecting them. Already before the pinga we had seen that array from Lake shore Humeau nothing, culde near the 1st lake line we hit just before the pinga that had been broody phalacrocorax. So we treked on down to the pond/lake/isthmus mosaic. It was a neat little shorebird center, with all the species listed above. Each margin of Archibelia had one or 2 phalacrocorax of either species. Scattered small groups of pectorals, breeding both broody and not broody, limnocorous. But curiously we found C. alpina and C. pusilla in only one place, the alpina on the lower side of a pinga and the alpina nearby (pinga 30 m from lake shore). Both were broody. Larus hyperboreus with one downy chick. Caria arctica probably upland. Anser allifrons w/grow. Walking back through the mosaic we passed through an area of low but regular numbers (i.e. 1 q melanotis every 100-300 m etc). Then suddenly we stumbled in to another center - 19 melanotis, 2 pairs of alpina, 15 chimaerops, 1 Puviali dominian, 2 juvenile pusilla, 1 Phalacrocorax. Habitat was not strikingly different from other small ponds in the mosaic, but the birds were markedly concentrated there. EVENING - talked w/ Wayne Hansen. His hostility seemed reduced this time. Learned that security likely to become more strict. Avoid Joe Morgan at Arco's bent strategy to make access inquiries at management level above turning on oilfield. Birds are inaudibly perceptible - a breeding Limosa fedoa at Franklin Bluffa. I want to see their photographs. High nest mortality there, an order of 70%, mostly due to July 3-4 storm.

JPM Myers 1977 Journal Prudhoe Bay, North Slope, Alaska 20 July (cont'd) But a heavy fraction also lost to avian predators. Low density: over 100 or so ha they found 8 meter mats, [illegible], C. calceolus, C. fulicarius, a few more of other spp. I am somewhat skeptical of the accuracy of these densities. With reference to Prudhoe Bay, Fauson tells me that melanotars do NOT vary in density to any great extent, at least over the last few years (1971 on). West Dock → Pt. Storkeuson Dew line 21 July 0900→1700 in field between Pt. Storkeuson and West Dock, scouting the habitat w/Dave Shoford. Weather began ominously in a sense, quite pleasantly + thickly threatening for mosquitos. But acold breeze and midday fog kept them down, and proved only slightly chilling for us. We traversed a diverse array of habitats, ranging from coastal salt marsh to lowland Cares pond/lakeside heavy on Arctophyllum and Cryphonium angustifolium to dry creekside ridge and upland Tundra. As I discovered in late June, [illegible] Pat Webber's description of this area as a Barrow analog is appropriate. But blooming Dryas kept me aware of the fact that we weren't at Barrow. Here the Dryas and Papaver are much more widespread in wetness regimes than at Barrow, growing much between moist tundra, as well as higher ridges. As yesterday, the general theme of the outing was absence, but not as stark as yesterday. Thin was probably a result of our never spending extended, uninterrupted periods in pure upland tundra. But not entirely, because even three birds could be found (P. dominica, C. alpina, C. lapponicus). We went through one very extensive lowland mosaic of ponds, lakes, + Carex marsh, ~1500 m NW of the west dock parking lot. This area had relatively high densities of expected species - C. melandrus, C. alpina, C. pumila, Ph. fulicarius, Cavia s+a, Somateria spectabilis. Very low polygonization here, except a high % surface water even across thin salt in a dry seam. To my surprise there also were Pluvialis squatarola - a flock of 5, and P. dominica - several small groups that represents [illegible] flock of P. squatarola I've ever seen on the north slope. Also explored a large salt marsh extending inland several hundred meters, bordered on the upland side by a wide swath of what it interrupts to be salt-burned normal tundra (a blackish mass of dead moss Carex?). Saw perhaps 2 Calegivis in all of that much - no shorebirds. From these there passed into a flat polygon region similar to Barrow draining moist meadow. Few pajaritos graced the land. Only within about 700 m of Pt. Storkeuson Dew line, just after crossing a Puccinella sloop,

Here + to the north small flock of Wilson's emerged out of the marshes, several groups of pluvialis footed about, etc. Met two people working for Dirk Dillman — Mike Coob and Fred ?, undergrads at Dover State. They were enjoying their work, obviously trying hard, but suffering from isolation in a biologically unlike any they'd ever been in. Large herd of caribou — 35? and 16 young fooling around the stabin, isolated 70? or in small groups nearby. From the DELA line carry we walked west w/1.5 km. w/ Fred + Mike — they wanted to show us some fox den sites + bubby display areas. Buffs have apparently used the Storkerson upland stream banks now for 5 years running. Habitat looks very similar to area in western reaches of oilfield (By Kup River). At 1500 we took off, heading directly SSW back w/ little tomfoolery. 1700 arrived at West Dock. This trip, as well as others during the last several days, indicates that in 1977 Pluvialis dominica was as common or more so than P. squatarola in the oilfield area. Such a statement must be made carefully at this time of the year because of migrant golden plovers — something regularly encountered. Black Golden Plovers appear to have been more common as breeders this year here than were Black-Bellied Plovers. I say that more on the basis of the rate at which we encountered the wreaths of broody adults (Blackbirds) of the two Pluvialis species — golden plovers many more broods around us than do Black-bellies, — and also from our preliminary transect work in June. Densities of P. dominica are nowhere as high here as they are at Barrow, but they're more than one would expect from Norton's work. Deadhorse Airport. 22 July 0900 to 1200 went through area in which transects G-7 were placed last month, and was astounded — appealed — to find [illegible] birds in what then was the most productive habitat. It was enough to make one speculate about the cumulative effect of nest predators + last storms on breeding success. It was particularly striking because the current distribution of birds — 30? in areas still wet + around lakes would lead me to predict at least a few individuals on this transect. The weather, by the way, was [illegible] poor — with a strong E wind, cloud cover and fog, temperature in the high 30's. Typical Barrow.

Journal Deadhorse Airport, Prudhoe Bay, W. Slope, Alaska 22 July (cut) and then headed counter clockwise along the lake. For the 1st third of this wild gyration we were in low Carex marsh - saturated or standing 120., extensive lakeside stuff. Not even any phalaropes. But one juvenile - recently fledged (2-3 days) - Calidris himantopus - putting this bird among the definite local breeders. Found another juvenile C.h. when 300m, even more recently fledged. Along this periphery we did come across juvenile pugilla in regular low number (1-2 every 300-500 m). As we cut S along the far side of the lake the wind rose, or rather, the tundra ~ 50 from the wet edge of emergent vegetation rose to a slight sloping rain. Began picking up a few phalaropes, and then the turners EXPLODED w/ a flock of mixed shorebirds using the SW margin of the lake + its surrounding habitat. 15-20 juvenile C. pugilla (mortality), 5 C. alpina, 30+ C. melanotos - almost all 4, juvenile + 1st Plu. fuligula Calidris BRUODY LIMNODROMUS SCOPACEUS. The C. melanotos adults + juveniles were also there. The flock spread over 100-200 m on the SW side of the lake - i.e. the downwind side. All its turn for another general review of the Prudhoe avifauna, covering the period 18 July-22 July. Gavia arctica - common water over oilfields on larger ponds/lakes. Uses small islands. Not quite close to road system. Pond depth to be deeper than G. stellula (see below) Gavia stellula - common water along road to West Dock + on Spain Road in a few places. not inland. one large pond w/ Arctophila margin, emergent grasses. Olor colimonum - rare meter at best. need to learn what distinct Olor has determined Branta canadensis - many pairs w/ broods seen along larger lakes shores on Spain Road Branta bernicla nigricans - several groups seen along larger lakes on Spain Road / woods. adults also out along West Dock road Anser alliformis - few pairs seen, three deleted from brood - lowland lake margin Anser acuta - violated 49 flying around, usually w/ others Clangula hyemalis - a few still seen on tundra ponds. hundreds in nearshore + offshore Chukchi in large flocks. 70+ and 99. Melanitta perspicillata - a few individuals seen scattered in Clangula flocks offshore Aythya marila - a few offshore in Clangula flocks.

I.e. at/in the low Carex marsh below the rim which defines a border between the marshes and uplands. Other flocks encountered in similar conditions, usually accompanied by fledglings. But also found in manic polygonized meadow (Eriophorum angustifolium flat center polygons) out by Storkesen, in mixed polygon/pond system (less frequently) and along lake margins. One C. groody pair on slope of Pingo S. of Big Lake. C. pusilla - few adults still evident except in one large flock (>50 birds) feeding 18 July one broody pair at base of Pingo S. of Big Lake on gravel by west dock. Juveniles widely distributed in some areas, but totally absent from others. If any pattern is discernible it is that near large mosaics of lakes + ponds you may find juvenile pusilla in low numbers in any of the manic habitats present. C. himantopus - one broody adult W of Buffy Pingo in lowland Carex marshes. 2 juveniles near Deadhorse, (barely flying), one around lake margin, one in LTW another UTC. Tryngites subruficollis - NONE Limnodromus scolopaceus - one broody pair mobbing us by lake side at Deadhorse EI vegetation, blue-wire only scattered flocks - very few - around lake margins in lowland wetland/lake mosaic. no all adults.

One chick seen, still very young 20 July. Xema sabini - ~110 adults along SW shore of one lake near mouth of Sag River estuary. Stoma paradisaea - adults foraging by Wet Dock in littoral. 110. Nycticorax scandiaca - fewer than 5 seen since 18 July Corvus corax - seen regularly in oilfield. No joint ed building Cleavis [illegible] - a few adults still feeding young, carrying food. very reduced in density compared to June, largely absent from most of tundra. A few concentrations found, particularly along rims above wetlands. many foraging on gravel pad by wint ducks. 87% molting retrices. juveniles as common or more so than adults. Phlethorhynchus [illegible] - only near buildings. Fledged juveniles present. adults molting heavily. 23 July Walker, Walker, Brown, + Everitt, Dric Murray, Al Johnson, Dan Larsen, et al blew into NANA taking after a roaring ball haul road trip and current to Fish Creek, when they will be doing post-drill recovery work. Actually not all of them go: Walker + his assistant, Norm 3 will remain, and we planto learn something about plants from them. But unfortunately the mailhouse of a Jerry Brown our dominata this place now interferes with work. Finally in late afternoon the crowd managed to reach Wet Dock the Barrow analog - I found that my Barrow analog was a bit misplaced from place, not equally analogous. Broody Calidris Bairdii Hare along the coast. 24 July morning went to Pad's 3+9 w/ Walker, Welder, Everitt, and Larsen. Turns out the area is old stream over (again in low places by Carex equally, and in upper places by a balsam tender type, with heavy frost striking dominated by Dryas, Papaver, Androsace, Silene acaulis, Pedicularis capitata, etc. We birds saw a few Phlebiae dominica flying by. During the afternoon Dave Shoford and I went out to the Kup area to lay transects, only to be supplanted by surveyors intent on destroying our traffic mixing area. So we returned to the Deadhorse vicinity + placed 5 0.5 Km transects in area where trans 6+7 had been previously. 89 fringing flats: as far as 1.5 Km from road

J Plligers 1977 Journal Produde Bay, N. Slope, Alaska 24 July On down wind side we kicked up a dust storm with every step. Brief transect description: (1) runs through mixed polygons and ponds (old than 6). (2) emergent way along NE side of large lake running into upper well and with M2 filled low center polygons. (3) flat center polygons of M2, running past several lakes, (4) same. (5) rim of lacustrine fill extending out into peninsula or isthmus between two lakes. In general these are mesic upland and lowland wetland transects, and should be rich with C. pusilla during the breeding season. Blocks of Pluvialis dominica moved past toward the east as we set out the transect suggesting C. pusilla quit appearing over 100m. Talked w/ Kaye Everett about polygon formation: Once you have the ice wedge pattern [produced via the Lichenbrad model of derivation of virgin surface inducing polygonal cracking whose dimensions are determined by the parent material] the following sort of succession sets in: [diagram] (6) rims continue to grow due to ice-wedge growth, forcing material up + in if thermal erosion of ice wedge begins or thermokarsting due to various agents such as vehicular drawing, etc.: LCB [diagram] FCP [diagram] HEP [diagram] So the production of HEP is not due to increased height of center but rather the increasing depth of the troughs. Events is not willing to accept the flaw-like cycle anymore (the reason for oriented lobes in the coastal plain I was suspecting their orientation may be due to geologic fracture patterns in the bedrock, J. Brown scoffed at this notion. Kaye is predicting a bimodal distribution in an orientation of the long axis, with a minor peak 90° from the one so evident even to the untrained eye at ~90° from prevailing wind. 25 July spent entire day in field w/ Skip Walker, learning about this Produde vegetation scheme, learning what to look for in [illegible] identifying various plants, and being frustrated by others.

Journal Providence Bay N.Slope Alaska 25 July (cont'd) @ my 26 June notes for listing of his vegetation units. It looks as if we will be able to deal with most of them, although he has obviously brought a different eye to the problem than that of an ornithologist. The clutuchman, for example, between M2 and M4 seems to rely largely on the basis of the presence of 2 mosses: M2 = Drepanocladus crepidiformis, M4 = Scopadium scoparium. Skip has difficulty at times telling these 2 apart. But M2 maims (given this line between M2 + M4) between a fairly rich stand of Carex spp., Eriophorum ang., Pedicularis sudetica, Salix arctica, Salix lanata, Saxifraga cernua, etc. (including Drepanocladus plus other mosses) to something barren save a mat of Drepanocladus, Carex spp. and a few scattered herbs such as P. sudetica. His physical appearance at this end of the spectrum is essentially - virtually - M4, except for Drepanocladus. I may change his categories a bit to correct this. Otherwise most is straightforward. It may be splitting to finely in separating out the Bad F site (M1, U1) because of the increased range of lichens - particularly Ochrolechia thure. Birdwise today there was little of note. Stocking Phloxia dominica continued to move past. Junivula C. pusilla are on the tundra, and beginning to appear in groups along lake shore margins. P. Ph. lobatus are flocking but also some still molt. P. Ph. fuliginans largely gone, with juveniles fuliginans becoming more apparent. C. melanotica in environment, with occasional 49 coming in to molt: no juveniles yet. C. himantopus has appeared in a flight by Deadhorse. Weather today was sunny with a strong E wind. Temp ~ 45-50°. 26 July spent another day in field w/ Walker. weather atrociously Barrowesque, with fog and strong E wind dominating: One saving grace compared to Barrow was warmer temperature - in mid 40's so that properly gabled the wind did not suck it out of you. We visited Drill site 2-[Little Pat River], West Dock, and East Dock. Most of team went to measuring these depths, with Bob Dave + I helping @D myself with wandering around collecting Carex spp. Birding was next to impossible with the wind and fog. there wasn't that much around anyways: flacks of Phloxia dominica, Caledris pumila and Phalegus lobatus. Spent the evening discussing the Providence area with Skip. I convinced him it was botanically useful to think about "regions" in the Providence Area, and try to delineate them. He did so on map on opposite page. 3 river regions- Sag, Pat + Ryp, with the first somewhat confined by the extreme sand dune dominated area, and itself a distinct region: sand dunes. There are 3 other regions,

The former two are similar macrohabitats topographically but differ in vegetation (somewhat subtly) because of locs from Sag River on Wet Calcareous Tundra. The coastal strip includes littoral tundra plus a small (?) gorge slightly inland still dominated by the winds off Pruville Bay. 27 July went out and did it! - placed 15 0.5 km transects (great) in the western region: 5 near Buffy Pingo (which I learn is known as Michelle Pingo), 6 near Pad F, and 4 south of Big Lake. Weather gorgeous, verging on the hot end of tolerable condition, with mosquitoes hovering constantly during 8-9 afternoon. Wind light southerly, no clouds. After a fog burn-off first thing in the morning. Brief transect description: 6-10 in the Sagelake Rip Uplands: ⑥ along Michelle Creek with much barren tundra vegetation; ⑦ running from Michelle Creek east over Michelle Pingo, almost all upland or pingo; ⑧ not actually placed as it will lie on the Buffy grid - will be mostly upland tundra ⑨ goes from Michelle Pingo uplands W down a ridge into the uppermost Put River terrace; has a bit of beaded pond; ⑩ along Michelle Creek on W side then heading more westerly over accord ridge - took a jog at 5 11-16 in the wet acid tundra of Pad F: ⑪ from parking lot SW across polygonized ground (wetly FCP and low HCP); ⑫ split, 82% requiring on a pingo, hitting another pingo and then leading glacialer from N/S lowland lake margin into FCP's; ⑬ polygonized tundra; ⑭ polygonized tundra along a slightly raised ridge; ⑮ begins on FCP ridge + plunge off through lowlands very similar to Barrow ⑯ begin by going across Anctophie ponds, then up onto lake ridge. 17-20 Put river uplands: ⑰ from over uplands with some E. vaginatum to Put River; ⑱ SW along edge of pit; ⑲ from lala region by Put along river terrace up onto low ridge; ⑳ along ridge w/f. vag., jogging to east to avoid screwed up lowland. Bird scene - we found several concentrated bird areas, typically but not invariably in disturbed (flooded) lowland. Significant avoculars: ① Northern Phalaropes - away in flocks; juvenile C. posilla - most abundant shorebird right now, in flocks up to 40 foraging in exposed mud areas; ② adult Fluvicola dominica - flocks in many places on uplands, occasionally into lowlands; adult Phalaropus spectabilis - one flock of 15, often small groups in lowlands; juvenile Phalaropus fulicarius not abundant yet but building; ③ Ayas aruta - saw 30+; broody ④ melanotus still apparent but no appreciable flocks; C. binaculata 5-10 using ponds near NANA. 28 July placed transects 21-27 out by the wet dock.

SPMayers 1977 Journal Prudhoe Bay, N.Slope, Alaska 28 July (cont'd) absolutely stupendous juvenile Calidris pusilla movement: Initially 1000's of these burgers, largely by the coast but also inland - this began w/180 C. pusilla juveniles by MANA in a seepage pond by the road, flourishing with a mix of Phalaropus fulicarius adults (~80), Calidris bairdi (6), C. melanotos (7), C. leucura, (adult + juveniles). After Shuford and I censused the area: C. melanotos 7 C. alpina 1 C. pusilla 180 ~ .75 ha C. bairdi 76 C. leucura 3 Ph. lobatus 80 Ph. fulicarius j 5 Calidris lay 10 Motacilla flava 1 But the real surge appeared coastally north of our central camp/impromptu, continuing as far as the Porcupine marshes north of west dock (as far as we went). Flocks of juvenile scapulifrons scattered everywhere, flocks ranging 50+ birds, foraging in Puccinella marsh, foraging on the gravel road top, foraging along lake margins in the coastal vicinity. We placed transects at West Dock within Naeling Island NW ~ 8 km. The pusilla were restricted to the very coastal strip, largely within 500 m. One extraordinary location was along the south bank of the Pot river in an area where salt water had killed an expanse of Carex lawrencei polygons. It was strewn with C. pusilla, many behaving aggressively, actively defending a 1-2 meters in length. Saw some classic calidridin aggressive patterns, including a crowch, wing out, etc. [see spp. accent]. Golden Plover adults are now very conspicuous also - occurring in both upland and lowland habitats but accepted toward upland. Phralis squatarola are also moving in, all adults, exclusively in low wet places. Transect description (3D) - begin near creek sock parking lot + goes west, starting on flat center polygon, out small arm + plunging into a marshy lake basin w/ Arctophila pond, Carex aquatilis, Hyperus tetraphylla, Ranunculus palmeri. Much Salix pulchra on Eip's contracting markedly with all other transects before today except the PAF series (which Skip Weller attributes to acidophilic tendency of Eip: and calcareous nature of most Prudhoe tundra due to aeolian deposits).

Ends by the Put River, picking up a patch of streamside snowbank in the process. (29) goes across a manic meadow on a river terrace, poorly polygonized, and then rises into an FCP then LCP area system, reaching well proportion than 28 to the extent of having some U4 LCP's. (30) races up along the Put River highlands, avoiding U2 + U3 upland trend but ending in the stream, blessed by a Squawingbird Dodecatheon frigidum tundra streamside. (31) returns toward NDS2 by angling across a river-side ridge very like of it companying on the river fall, but under its influence. Second Unit crosses a well drained stream hollow. (32) [on the east side of the road] is old fashioned U4 LCP, but ends by heading up a Paperar-covered ridge. We had a bit of problem placing (33) and (34) because of vehicle tracks and an old (1969) road as well as loose electrical wires. (35) goes from the edge of the Paperar ridge abruptly into a fine looking mixed mosaic of large ponds + well defined polygons. Promises to be hot stuff with its Arctophila cover. (34) covers LCP's dominated first by U42 then U4 and if it moves into a pondier area, not tremendous vertical relief (34) is split to avoid the disturbed road site.

Journal Prudhoe Bay, N Slope, Alaska 31 July (cont'd) Pluvialis dominica (cont'd) hour on tundra. very few broody adults left. none seen in full misted plunge. Pluvialis squatarola & flock seen regularly. this is exclusively a lowland bird at Prudhoe now, at least for individuals in migration. Flocks up to 15, often w/ one or two in nearby full fleeding plunge. uses vegetated flooded lake basin or bare mud, both in littoral zone and in tundra away from coastal region. Arenaria interpres - none seen since 22 July Calidris melanotos - a few broody eggs still around. one found w/3 chicks ~1 week old on 29 July, suggesting a clutch completion date as late as 5 July. Most calidris marshes have a broody & or 2 or up to 4 at once have incubated us within last 4 days. no brood buildup of migrating &. juveniles becoming a regular but very scarce commodity. Calidris - fledged juveniles seen in a number of places, usually along littoral. Broody adults also encountered. My strong feeling is that they are largely a coastal breeders, using the "bluffs" along sloughs and rivers by the littoral. But they also breed on higher snowy sites as far as 10 miles inland (who knows about further) e.g. on pingos or crevices. If any calidris breed in the Sag River consolidated dunes (P-19) it will be calidris. 5 juveniles seen on Sag River gravel bar 31 July C. alpina - juveniles fledging. adults flocking. not a bird to expect regularly in count or in any given place but found regularly + quite patchily, such as on occasion we happen across flocks of 10-15. also lowland and somewhat into uplands + mesic polygonized tundra. adults molting, but black patch not yet conspicuously blotchy. C. pusilla - adults have disappeared abruptly, juveniles invaded (see sp aceat), counting 28 July w/1000's along littoral. Differ from Barrow in that here they are also conspicuous on some tundra locations. Flocks seen regularly moving hardscrabble. Littoral habitat: largely Ruddy Plover, Phalaropus fulicarius, foraging along receding water line in very yucky mud. Their scutellation probably saves them from a La Brea's fate, sucked into red muck. See sp. account re appearance

JPLigers, 1977 Journal Atkasook, Ulead River, W. Slope Borough, Alaska 2 August (cont'd) Whether fire induced or not the lily hay is oppressive and made worse by the muggy heat. Oh for a cool ice breeze off the Beaufort! Shorebirds restricted almost exclusively to stringbogs and unpolyploidized Carex marshes. But there are few of them, with the 2 Pluvialis spp, and Calidris maculata j and juveniles being the only throngs encountered avidly. See daily list, transect summary. One Gallinago gallinago in a Carex marsh. Abundance of juvenile Calidris along ridges. Passive movement appears to be underway. The tundra is excessively dry— even many LCP centers with Carex aquatilis and Nostoc (analges) are bone dry. Vegetation → perhaps the problems arise in part from attempting to assign all sites to a set of discrete categories. But that is little consolation. There were many stands which we had tremendous difficulty in dealing with, i.e. in placing in one of Vera's units. Partly that is a result of insufficient information. We used a list of spp which accompany the defining species, because the latter are not always present. But Vera also relies upon land form, such that [from the linked info are here], the same plant species associating in 2 separate arctic microhabitats (i.e. physical microhabitats) may be split into different associations. (No augusta!) It is also disturbing to see the variation in physiology of vegetation which exists within a given one of her associations; that is if we are correctly assigning stands to her system. This holds true, for example, in the Carex aquatilis-Carex chordorrhiza unit which grows in the centers of LCPs—vegetation height + density vary a great deal. 3 Aug — returned to WARC after waiting all day for plane 4 Aug — work inside at Barrow 5 Aug — flew to Deadhorse, Prudhoe Bay, Alaska Worked w/ [illegible] language all afternoon. Did lone him for brief survey of NANA ponds, out behind the sewage lagoon tank here at NANA. 15+ juvenile Calidris hudsonica, 35+ mixed adult + juvenile C. alpina, 20 C. maculata juveniles, 30 C. pusilla j, 10 C. maritima j, plus at least 50 Ph. lobatus juveniles. The species composition has changed markedly since I left, and the ratio of adults to juveniles has also shifted.

SP Myers 1977 Journal Deadhorse, Prudhoe Bay, N. Slope, Alaska 6 Aug 0700 beginning to sample transects w/ Dave Shuford - running two very different areas: the East Dock + Sag River set and Middle Ridge + Angel Pogo transects. Activity near East Dock and the Sag is quite high - many Celeleius juveniles flocking about, and shorebirds popped up in many transects. An extraordinary # of Trypette today, beginning w/ a 9 w/ broad in T39. See sp. accent. Golden obvious but considerably less abundant than last week. The highlight was a pair of juvenile Limosa haemastica in some littoral ponds SSE from East Dock by ~1 mile along the road. In contrast to the activity level in the eastern sector, i.e. the sand dominated region, the pace of activity in the west was much slower, with fewer birds seemingly restricted to fewer areas. This may largely be due to the coastal character of the sand region, and/or it is in a position to pick up the coastal migration movement. Haul road - Deadhorse to Toolik Lake, N. Slope, Alaska 1815 left Deadhorse w/ Dave Shuford and Claire Buchanan driving south along the haul road. We reached Toolik Lake (~68°43'N, 149°1'W) at 2330 after a slow but steady trip. Weather gradually deteriorated, becoming foggy with scattered rain as we proceeded inland and up. Had been clear at Prudhoe. We made very few stops en route, and I therefore will refrain from any extensive description until writing up the return trip. Fog obscured much of our view south of Sagavanirp Highlands. See daily list for spp seen. Found one "pauper" near Franklin Bluff - a wolf that has learned to beg from passing trucks. Sampled two roadside ponds with Claire - she works on Daphnia and finds a succession pattern involving 2 spp D. pulex (light) and D. m. unhaudordiaria (dark), with pulex moving in to newly formed ponds first (but being replaced by D.m. later). Apparently D.p. is adapted to electrophilic situations whereas D.m. to nutrient poor conditions. D.m. also more resistant to a heterotrophic predator because of its dark pigmentation. Haul road: Toolik Lake to Chandalar 7 Aug Again a rushed trip - this time w/ the intent of catching Vern Romankova (IAUSTAR) to discuss Mackel River Vespidae. Foggy from Toolik over first 10 km, then low fog up to Ahtaga Pass, but clearing from pass south to Chandalar. We left Toolik at ~0930 and arrived at

The bird communities are summarized in the table presented on the last 2 pages. Sites 1-3, with their emphasis on avoral community stand out as distinct. The Brooks range site, dominated by Whistlers, Water Pipits, and blessed with Northern Shrikes in small number, are also consistently different. Foothill sites grade from Brooks Range into coastal plain, but differ largely in the conspicuous abundance of the Yellow Wagtail, Motacilla flava. Coastal plain sites are shorebird dominated, but the influence of this taxon began to be manifest in the foot hills, particularly at disturbed roadside sites. [NOTE - 1 C. posita juvenile was seen banded —; YW at Station 16] A riparian set of species—Spizella arborea, Zonotrichia leucophrys, Passerulus sandwichensis,—persisted throughout most of the samples wherever their peculiar microhabitats could be found (see below).

JPMeyer 1977 Journal Meads River at Atkaook, W. Slope Borough, Alaska 12 August Arrived Meade River 11:00 on a NARL historic flight - the first twin otter landing at Meade. They came down to transport Bob White's recycler back to civilization. Discovered upon arrival that Lynn was sick, so I found out where she stood in transit cycle + sampled Flea host 5 that needed drying this period. There were transects 6-10. It was a good refueler for Meade, though perhaps a bit barren for birds. The tundra is dry, with many low center polygon centers, no longer even damp, even those covered by Carex aquilis - Carex chordorrhiza. Most shorebirds were encountered in the lowest areas, either extensiv Carex marshalli by lata margins (transect 6 which had 21 juvenile moults) or big on bare margins of receding ponds + lakes in more polygonized ground (transect 10). C. alpina appeared restricted to the latter, while eulanda was more generally distributed, even though heavily concentrated in unpolygonized marshes. Black-Bellied Plovers are the only bird conspicuously with juveniles now: their circumsant moulting and alarm calls are bothersome - piercing and continuous. 13 August Worked on vegetation today, sampling transect 1 as we have done the transect system at Barrow. Some alterations, the most fundamental of which is that we use Vera Komankova's list of associations worked out at Meade instead of Pat Webber's from Barrow. There are difficulties, not the least of which derive from the complexity of Meade vegetation. Vera recognizes 90 (minus) associations. Fortunately several are quite rare or restricted to areas where our transects do not occur. But that is still a shuffler. But the complexity is also manifest in unforbidden intergradations in type. For example: the dominant upland vegetation is what Vera calls Eriophorum vaginatum - Ledum. At o the classic tussock tundra, although occurring on well drained uplands of varying degrees of polygonization (from trough height 10-80 cm). Tussocks are variable in size but smaller here than in haul road sites, ranging only to ~15 cm high. Anyway - the E.v. - Ledum association is thick with fruticose lichens, especially Cetraria spp., and has a number of vascular associates: Rubus, Betula nana, Vaccinium vitis-idaea, Carex bigelowii, etc. But the proportion of these associates in terms of % cover varies enormously, as does the % cover of Ledum + E.vag. They vary so, as such that

Journal At Kuoola at Meade River, N. Slope Borough, Alaska 18 August (cont'd) pairs during the day without hearing one of them, and often all three. Anser are the most conspicuous: any lake has a pair of chicks, an adult tending one chick the other working on the other. Foraging for the chicks appears to be right below the chick, with the adult rarely under for more than 3 or 4 seconds, staying right beside the chick. Cairina scutulata, by contrast, I see flying between Smakrach Lake and wherever they are nesting, carrying fish (8-12 cm) cross-wise in the bill. They have been excessively noisy, ack-ack ing in flight, giving the sandhill crane call from their lakes, etc. Cairina adamsii I rarely see flying, but its yodely emanate from Pingo Lake continually. Larus hyperboreus: young fledged in one nest by June 14. These must be the first active mackerel this year of which we were aware, and an probably the first of fledged young. 19 Aug T4 finished. More snow patch trouble 20 Aug T14 started and finished. We have speeded up the process by splitting the Eriophorum vaginatum - bedrum upland tussock tenders into 4 separate groups. How does splitting speed things up? Because the E.v.-L. (Umi) association is so broad in its moisture gradient occurrence (from what we can deduce from Vera's info) that it often takes some effort to assign wetter extremes to Umi. The anquish this causes takes time. By splitting it up we break endless tasks it easier to do the job because we don't have to pain over the assignment. 4 sub-associations are: UMIa - Umi with a snow patch matrix (i.e., E.v. tussocks growing in a matrix of Rubus, Hectonia, Elymus, Cladonia/Clavaria/Cetraria lichens). This is the matrix in which Umi appears as an undifferentiated polygon mass, particularly HCP's; UMIb - E.v. tussocks in SB3 (Rubus - Balsamia - Sphagnum) matrix. This is a much wetter type, often appearing on lower polygon rims w/ SB3 centers. UMIc - the upland tender matrix - often thick but low tussocks growing in matrices of more Eriophorum vaginatum, bedrum, Rhacomitrium, fewer fruticous lichens (and no Aleochara/Coronularia). This occurs in driered but flatter areas with little polygonization (in fact frequently near) and reduced topographic relief. UMIcd - thick Carex, usually biglottic brand reduced tussocks, often almost not apparent. Much wetter but still not the E.vag.-Detricha many semi-bog association.

JD Myers 1976 Journal At Kasookat Meade River 21 August T13 complete. A glorious day, with me working up a flurt on from 0930 to 1900. Abounding for the tundra. Almost no wind. No mosquitoes (too late in season). And T13 was a joy, largely comprised of Carex marsh beside Pingo lake. The transect runs along the lake shore, and each parallel set of transect units straddles a recurring 50 plant gradient: [sketch] see attached list of plant annotating (opposite page) for key to plant annotateria. Transect 13 runs in a line parallel to the cliff, that is, out of the page. The shale line runs roughly down the zone just water-ward from the silicified zone, making most of the area within cuts on the right colour under water or squiddy. A3, thin stands of Antropila fulva, grows out in standing water. (Carex aquatilis - Peltomonium actiflorum (HL1) is a thin (1-2m wide) strip of slightly raised turf occurring in many but not all of the transects. Given how dry the tundra is this year HL1 is not even always saturated, and there may be a meter wide strip of bare mud waterward from the HL1 strip. In many places the transition from vegetated bog (B7) to water (A3) is merely a slow luxuriant growth of B7 - Carex aquatilis to heights up to 45cm. This typically occurs where there is no raised shelf along the lake, a shelf acting as a substrate for HL1. B7, largely saturated, in a mixture of Ranunculus pallari, Carex aquatilis, and (sometimes) Caltha palustris. Substrate is generally sross-free, although when it integrates with B5 or B6 there can be Dropanocladus. Instead of mosses it often has a scraggy red much for a bottom surface. Patchy of B5 occur within B7 on the drier side. In fact in the interface between these two Ranunculus pallari can grow out of Dropanocladus

Constant hooting. In LCP areas densities really high + comparable to Barrow based on a few observations of territory size. One 8& (watched in (v1938)) defended an area bounded on all sides by other 8& no more than 150 m diameter (see journal). 8& not incubating yet, but definitely established locality. However significant #s flying past to NE from here. 3 June saw 8& giving hooting 8& a tail up (buzz off) display. Does she have a complete catch? Many 8& are around now, left flights of 8& continue to NE (see journal. 4 June unable to locate any nests yet even though 8& obviously localised). Jang [illegible]

J P Pligers 1977 Calidris melanotos At Kasook, Wildlife Meade River, N. Slope Borough, Alaska 4 June (cont'd) 8" shooting, groove displaying (at all levels of curiosity from simple vocalization to entire shrilling w/ rolling groove call). But 9" continue to fly by to NE. In fact today I saw a number (>50 9" in separate flocks of 5-15) even during the day. A Hyp: these 9" are looking for concentration of 8". The 8" spend a lot of energy chasing few 9" flocks when they move by, flying up at them, shooting in chases (flight + finally wheeling back to their territory. Could this be the way that opportunism is expected? - go to a place w/ many 8"? I am struck by the similarity in movement between melanotos and Stercorarius pomarinus (see journal 4 June), Pictorial habitat: 8" almost everywhere, including along ridges. 9" more restricted, mainly in areas comparable to Barrow. 5 June 9" must have chitter by now in many places. Activity down. Several 9" screeching tail up [lay-off] display to 8". Also acting as if they have a metallic nest (typical alarm chirr). 6 June Dave Best (camp manager) showed me a complete melanotos clutch behind the labs. He found it yesterday. NARL, Barrow, Alaska 7 June on GRISITE. Aaah! only 3 8" in area. One pellet hood. Perhaps 9 9". Shetford + Erickson report few melanotos in Barrow area, At Karaoke, Meade River, Barrow AK 9 June shooting + other display activity much diminished save in the lowest areas. Along ridges and in earlier melting sites 8" are conspicuously absent. Poux string (loop) and lakeside margins are now their most prevalent display sites. Also observing obvious 9-9 aggression such as I observed last summer w/ 9" w/ broods. Simple chases, supplantations, from around nest area, Barrow. 12 June Jeepers. This am. tracked a melanotos with the largest territory I've ever seen in a pictorial. Tracking data did not include entire territory I think because no swooped out at all

JP Myers 1977 Calidris melanotos NATL, Barrow, Alaska. 12 June (cmt'd) 200 m beyond south edge consistently, sociable banking display. The tracking area included 10 ha. Incredibly because of the low density - Hooting infrequent, over possibly 2 q. Unfortunately the tape aborted after 14 min. I am surprised to see there appear an appreciable # of transient P.O.T morning by. 13 June GR104 tracking - did well on one bird but in afternoon was misled by another. curious events out here, with definite non-territorial q around, inconsistently tolerant of conspecific q. 14 June returned during o.w. to track - did a P.O.T each for 100 minutes (6/14-77-3, 6/14-77-4). They were the easiest P.O.T to track that I've ever done, because of the small territory + their low activity. Virtually no time lost! Also - and probably at the root of it - no q, save a quenchable q w/ 6/14-77-4 at the onset. Why quenchable you ask - because there are q around now with poorly developed chuits and the behaviour of other P.O.T part of GR104 are INCONSISTENTLY TERRITORIAL. Thus 6/14-77-3 and 4 showed some area between them, and appeared to feed tolerantly even though only 20m or so, for several minutes. #34 finally did push #3 off the area, but such lackadaisical supplementary at this time of the year is a NEW thing for me. I suspect that it has to do w/ a paucity of q. To what extent might the P.O.T a territorially be due to habitat? After all, GR104 is pretty low - being heavy on Carex-Eriophorum russeolum and ponds. But last year even their site were defended assiduously. q are the key. No q, no defense. Not immediately, but if the chances of q are low enough, then no defense will occur. The afternoon melanotos of 13 June on GR104 has a territory at the base of garden. It may get a reasonable rate of q intrusion, making defense worthwhile. 15 June which tracking q fidelicus on GR1 saw 1 flock 10 q melanotos go by and also came across several q on grid. Has there been an influx? Also, how have P.O.T responded? Dick also saw 1 flock. 17 June great deal of q melanotos activity on GR104, with several q settling in area. Had we been working on pictorials we would have caught it all.

JF Myers 1977 Calidris melanotos NARL, Barrow, Alaska 19 June good tracking scurin today on GRID 9: 488 with consistently defended, small territory (see tracking data book). However there was only 1 (one) 8" seen on the ground. obvious surplus 8" moving around. a flying 8" brings up 8" from at least 500 m. away. 20 June poor tracking on GRID 4: it took us several tries to find a territorial 8" in one part of the grid. There are at least 2 areas out there where no territorial bird holds sway. nonterritorial groups meander through w/o being disturbed. No 8" on ground. much chasing if a 8" detected in the air. one 8" strayed repeatedly into neighbors territory even though it was also territorial . 1050 began following 8" that within 9 minutes revealed itself as an NIB by ① being supplemented from local foraging site then ② foraging w/ 2 other 8" that also had been supplemented. This 8" confused me at first by grouse-displaying at one of the other 8", even to the extent of tail cocking. Predhoe Bay, N. Slope, Alaska 21 June 8" melanotos a conspicuous bird here still reproductively active. There are more 8" here than at Barrow, and 8" are probably equally or more dense than at the GRID 4 hot spot. Certainly more dense than birds on GRIDS 1 or 2. Curiously few aerial chases, even though hooting is regular if infrequent. Several 7-8" border interchange. 22 June Pectorales do not use perigas or upland lundra, at least at this time of the year. Put water on it and provide a few mounds (so they need be no higher than 20-30 cm) and you'll have a 8". Decustes may be higher in the [illegible] between [illegible] funtura moraici w/ strong [illegible] [illegible] (vari. Frii). But [illegible] tran 2 (see journal map) which is pure low wet tundra had a remarkable density along as well as more 8" than I'd seen all summer. Barrow, Alaska 27 June 8" arriving in hordes, swarming over GRIDS 1,2,3,4. Some 8" in blue flowers also. Few display activity still apparent, and where it is it is sporadic. Tracking is over 30 June [illegible] many 8" in lowlands south of town. possible feeding territory by lake margin.

JPM Myers 1977 Calidris melanotos Barrow, Alaska 1 July What given? We are being invaded by melanotos. That in itself is not unusual for this time of the year. What puzzles me is the # of PP in the flock, obviously not breeding locally. 5 July melanotos numbers down abruptly since 1 July (140 total ♂+♀ decreasing to 37 on transects. 98 in mixed flocks w/♂♂ 28/19 more or less. On trans 6-10 today found no more than 399, w/ broods - none of which I saw. (see Journal). 11 July a second peak in ♂ numbers arriving now strongly mixed w/♀♀. See transect summaries. It appears that unit (17,1)(18,7) and (19,1) are used each year by ♂ flocks, located as they are on the downwind (SW) side of South Meadow Lake. A flock of over 20♂+♀ melanotos on the lakeshore + immediate marsh there, mixed w/ a few maria and 40% fulicarius ♂. melanotos is now scattered widely over most transects in loose flocks. 45 ♂♂ on T1-5 this a.m. SW side of Meadow Lake 14 July out on S. Meadow Lake 1400. territorial ♂♂, probably territorial ♂♀ here, scarring up wind blown material along the lake shore. Territorial areas small, less than 10 m long and 1 m wide - i.e. they are classic feeding territoriality. over 30 melanotos here doing same. They have been here since the winds began 6 days ago. Collected 29♂ to look at molt + good condition. NTB present also for note see next page 15 July melanotos still territorial here along S. Meadow Lake. watched for 20 min as several supplanted consistently. Territorial area smaller than I originally estimated, some areas less than 3 m long. Good boundary defenses seen - tail down, crowd, chewing and supplanting. Several certain ♂♂ also involved, probably territorial, certainly aggressive. much aggressive vocalization, clucking. one ♂♂ giving something clonal like a continuous churr in flight, hovering over a very local spot (actually flying into the wind not making any forward progress, 8/10m off ground) when a flock moved in probably because I was present. I sat down to observe but they failed to adapt to my proximity. ♂♂ fulicarius present along same lakeshore in same sit not supplanted (nor supplanting - showing no sign of aggression)

JDVayens 1977 Calidris melanotos Pt. Storkesen, Prudhoe Bay, Alaska 21 July Late June / early July. They found only 1 nest this year, one still being incubated 4 days ago, they have not detected an overwhelming abundance of migrating melanotos. Prudhoe Bay 28 July Moulting 99 still encountered in lowlands particularly out lay-wet dock region. But as of today we are finding juvenile melanotos, and the overall abundance of 99 appears to be dropping. 31 July see Journal Haul Road, N. Slope, AK see journal. Juvenile melanotos as far inland as lower Brooks foothills in disturbed ponded areas. But not many before reaching coastal plain. +Kasook on Meade River 13 Aug Juvenile melanotos apparent on tundra in low Carex neopolygonized marshes, along bare mud at lake margins, particularly where there is overhanging vegetation, and particularly flying over in small groups - 5-15 (birds) - headed east. 18 August Very few melanotos still around, all juveniles. However I still see a few flocks headed E.

2 JP Nupus 1977 Phalaropus fulicarius GRID +, Carline Road, Barrow, Alaska 29 May ~2000 Dick Erickson reports 1 ♀ fulicarius this evening. At Kasook, Meade River, N. Slope Borough, Alaska Phalaropus in some areas abundantly, but w/ remarkably skewed sex ratio. We observed few males out of the 50+ ♀♀ in various areas, and estimate the s.r. to be at least 5:1 if not 8:1 ♀:♂. In one location w/ 2♂♂ and 2♀♀ we watched 2 ♂ fight for 3 consecutive minutes in one spot literally on top of a ♂. The ♂♂ were violently pummeling on another, grappling w/bills, butting w/ feet + wings falling down repeatedly. The ♂ crouched down so low under them it was often invisible on the tassocks. After having at it in one place they flew when the ♂♂'s stopped fighting + the ♂ left, followed by the ♀♀ who quickly began fighting again. Such frenzy I've never seen at Barrow. 9 June obviously paired fulicarius common now on hundred ponds. many more ♂♂ around them before, but still a ♂ biased sex ratio. Most appear to be using small ponds with any edges but they also can be seen along the larger lake edges. Much more numerous than Ph. lobatus Barrow, Alaska 7 June very few around, mainly ♀ biased sex ratio Atkasook, Meade River, N. Slope Borough 9 June phalaropus copulatory 10 June I have seen several instances of ♂ supplants even though it is obviously still paired, occurs when "intruder" flies in to local settled area. ♂ flies up + begins to fling its feet out, forcing the other bird to fly away, then it returns to perch mate, ♀ goes into a preening chorus, + finally becomes quiet. 14 June Barrow Began tracking fulicarius on Grid 4 this pm. Located 2 empty but in progress nest cups, one ♂ with complete clutch. a heavy (10+) of ♀♀ moving about in addition to at least 10 pairs. See tracking records.

S.P. Myers 1977 Phalaropus fulicarius GRID 4, NARL, Barrow, Alaska 17 June observed — w in 4.8 of GRID at 1700, acting as if there were no ♂ in her life. She can't be done w/ a clutch, as tracking her 16 June showed she was still investigating mating cups. Is this a regular feature in a stage of fulicarius ♂♀ relationships? — Once a ♀ begins laying the pair spends time apart? Tracking g/y today had her separating from ♂ for considerable periods (15-20 min) and then rejoining. What given? Also had ♂ of g/y attempt to copulate w/ other ♀ — not supplant but copulate. What given? Am impressed also by the ways of ♂♂ who males — r.i.r. His around jumping on other ♀ backs. Prudhoe Bay, North Slope, Alaska 21 June red phalaropus set the lowland habitat here, but I've yet to find an area with densities comparable to Barrow GRID 4 in its heyday. That may be due in part to the late date + reduced quantities of birch after the height of bleeding. 22 June did a little ledger on 'vole' densities today and set transect 3 (as way in journal). Habitat is low wet tundra with a few interspersed ponds, as well hummocks up to 20 cm height. 95% water cover. Vegetation appears to be largely Walker type M4 (Carcx aquatilis, Carcx saxatilis, and Scorpidium scorpioides). fulicarius have also appeared in much more hummocky regions with small trough ponds, and in somewhat more mesic lowland tundra complex featuring Carcx, Pedicularis. All together there is no suggestion that RP's are doing anything different here than at Barrow. Barrow, Alaska 28 June any discussion of space-use by RP's must face the observed fact that muttons can be located far from the foraging ground. e.g., birds foraging on GRID 4 may be meeting on gasoline ridge — the ♂'s of the mutton to forage, going several hundred meters. 15 July ♂ fulicarius foraging along SE side of S. Meadow lake when melenotes are territorial (see melenotes sp accent) ♂ fulicarius not aggressive at all, with constant changes in ♂♀ respective position of different individuals along the lakeshore

JPM Myers 1977 Tryngitita subocticollis GRID 3, NARL, Barrow Alaska 30 May gird unit (B,7) found 4 buffis at 1530. At least 2♂, both large + lustrous buff, displaying frequently in cup display and single wing up How gorgeous! Heard 2 different calls, one the usual low chuck but then another which I'd never heard, and one much more suggestive of the buffi's Calidridiae origin, a raspy almost note almost a cross between alpina and melanoto, about the length of a typical melanoto flight call. Rough and rather nasalish. At 1730 Erickson found 3 T.s. in the same spot (I'd told him about them). N.Slope Borough. Atkasook, Meade River, Alaska 2 June 0900 1 Buffy on a ridge behind camp. 1300 (41,25) a buffy lek w/ at least 5♂ spread over 500 m² of tundra. tremendous displaying activity. Flouncing about, Flopping up and down w/ awkward wing beats. Parabola display, single + double wing raises. But it bothers me that there is so much interaction between ♂ - not just visual. Certainly the display alone will evoke those of another at quite a distance. But they also visit, fly off / come another, and don't seem to be as (localized) as a good territorial lekking spp should be. Some compounds pass. 1630 Coming back from lee river came across more Tryngitita displaying activity, their lek (26,39). At least 10-4 displaying birds, perhaps more. Again a peculiar lack of space- specificity in all activity. Mixture of aggressive antivocalism w/ displays. But not obviously consistent. Habitat much wetter than I expected, with low wet tarey - Salix polycarpa over much of the area. It is quite possible that this area is continuous w/ the one we faced this a.m. - in fact it is almost certainly so. In that case the total area extent includes a lek 750m x 500m. The flop display is a very awkward flouncing up + down in place - flapping wings, jumping, getting ~30-60 cm off the ground. It looks as if they are just trying to make themselves as conspicuous as possible. They often wing-ups in several ways: first just by standing stationary, raising + lowering one wing or simply holding it up (looking from head on). They

SP Myers 1977 Tryngites subborealis At Kasook, Meade River, North Slope Borough, Alaska 1 June (confld) run while holding their wing up also. then Another more subtle display entails a bird with others which stands very erect and holds its tail slightly down They walk around like this. Also have seen aggressive crowded involving 2 birds, so also classic calidridin aggressive tail-lowering. 3 June back in same area this p.m. placing transects. walked extensively through both sites, but found buffle (3) only in 1: the (26,37) region near the end of Transect 8. Active displaying. (4,32) Meade River 5 June 2 buffle foraging on Alctowig beach at 1600 9 June out in buffle dorm today at 1030. 1st encountered en route. 1st in same place as last encountered in (26,37) - displaying actively but no Paralola. wing up seen, flutter flight, and a very high flopping. the buffle displayed + fed in an area for 10-15 minutes (or less) and then flew a short distance (100 meters) to another. repeated ~ 6 times. then flew off north along the ridge, perhaps to another display site. It looks as if the bird is adjusting its display to decreased density of birds in area, making them visible at longer longitudinal distances. Brothoe Bay, W. Slope Alaska 21 June 1 (unidentified) flying by 22 June ditto 23 June 0800 again saw a buffle cross the road, this time in the same place as yesterday, a point where the little Potuligayak river meets close to the road, upstream (south) from its crossing. Before I'd gotten out of the car the 1st (very big & bright) was single wing flashing + flutter jumping. Walked over, found another 2nd + a smaller bird, probably Q. The 2nd 8* was following this Q, paralleling mostly within 20 cm. Q ignored him I think, and flew off. That 8* disappeared. I returned to (1st 8*) (40 m away) who remained for ~3 min + then flew (some helicopter flight) ~70 m away to another foraging position. I left. 1030 found 8* on T-4 on river bank.

JPMayers 1977 Tryngite subvuficollis Produce Bay, N. Slope, Alaska 23 June (Contd) 0130 walking around the "Barrow analog" (see journal) found 2♂ Tryngites displaying - a good helicopter flight with legs hanging loose in flight (yes that's in flight). A bit of flutter-jumping. No♀ 24 June Tran 2 - ♂ Tryngite displaying on a pingo! first saw flutter jumping, then curing flash. It was near Hucutt but moved off quickly. 1100 passing near same pingo saw 2♂♂ in border display: they flew up together rising ~ 20m above ground vertically as diagrammed, fluttered way up (high), then returned down warior on same trajectory. 25 June (uffis all over transects, beginning w/ #8+9 in morning. ♂♂ conspicuous at several hundred meters in border display flight - no their spinner change up flew 2 beside fluttering together at 50 m+ off the ground. Buffy Pingo (see map 26 June journal) - (uffis coming out the gump shumps. began at 1500 when I picked on up on T11, foraging at the top of the creek basin. then as I continued along T11 I could see ♂♂ over Buffy Pingo in border display. Then on T10 I recorded another. Finally, returning toward the pond 6 ♂♂ began hopping + jumping all around, generally chasing, calling - tic-tic-tic in the air as they came down from the border flight w/ outstretched wings, head jerking (a flying Parabola??) Also giving flight chunk. Stumbled over next on side of pingo within display area - 4♀ w/ a delicate + very tolerant ♂. Nut in upland tundra, some Eriophorum vaginatum present (but not a good stand) of E. tussock tundra. A bit more moist than quickly that. Salix reticulata lining next. Then at 1850 along T5 I encountered 3 displaying ♂. I was virtually beneath a no pair of ♂ in vertical border flight. heard nothing but as they flew out of it one of them went into a very pronounced shape + dove back to the ground, something reminiscent (strongly) of a Calidris ruficollis glide flight (see 1976 notes) 29 July been been in Prochor since 18 July w/o seeing Tryngite (see daily list). Then today in stabilised dune by East Dock saw one adult ♂ w/ 8 Pluvialis dominica

J Pllyers 1977 Pluvialis squatarola Atkasook, Meade River, North Slope Borough, Alaska 31 May Pluvialis displaying this evening (1900) in my first jaunt around the Meade River tundra. Display call lacks the ringing quality of dominica, and is curtailed a plaintive 2 syllable whistle —— about 1/sec. in a muttonkey. Butterfly flight exaggerated. Other area × vocalizations also. Commonest along ridges. Paired. © obviously duller than ¨. 4 June I reaffirm my above notes about habitat of squatarola - definitely a ridge bound side but some individuals also using lowlands, even lakeshore. Seen one aggressive individual of dominica in which dominica came out winner. 7 June squatarola actually occurs quite regularly in local marshes. Pruoboc Bay, N. Slope, Alaska 22 June I had expected to find P. squat. more commonly than I have so far - in 2 days 2 birds. One was displaying on a pingo in typical flight display - it supplanted a P. dominica. The other fled by a low lake margin. 24 July see Journal. P. squatarola adults conspicuous now on tundra, many in small flocks into low wetlands. A few still broody. MEADE RIVER 18 Aug see journal. Largely unmolted adult squatarola still feeding broods + intraspesifically very aggressive, chasing other squatarola away. Some broods tended by 2 adults. Habitat use widespread but juveniles appear to be in marshy areas. Juveniles plumage tawny rather than P. dominica and white tail patch readily visible. Even though juveniles have fledged adults are still feeding young, mobbing. 18 August It's been 2 days since I heard any broody © squatarola, one hounding a parent jaunt near camp. Then today found flock of 2-4 squatarola juveniles moving around together. Foraging in uplands (?), flying by. This may be the squatarola migration

JPMyers 1977 Calidris mauri Atkasook, Whale River, N.Slope Borough, Alaska 9 June western sandpipers are still displaying on the tundra today (see summary in 5-6 June Journal for previous obs). I find their habitat distribution puzzling: they certainly are most apparent on slopes near low flat wet areas or ponds + along stream courses. But that description could be used to fit almost any patch of tundra here. I've even found what is almost surely a monkey bird near the crest of the ridge in (14,30). The effect is to produce a decided pattern to their dispersion which cannot be simply explained on the basis of habitat distribution. There are hot spots of displaying birds - areas where repeatedly we find active P.B. in chance. And these sites often seem unpredictable from tundra physiognomy. The amount of aerial chasing is stupendous - groups of 3-4 or more chasing around whinnying, or a P1 floating above a site, croaking with its feet dragging. And their ground displays - spread wings, round tail are just as elaborate as possible.

SP Myers + 1977 Vegetation notes: River bar association At Karook on Meade River, N. Slope Borough, Alaska 26 Aug Today sampled the only few patches of river bar we have on Horseshoe (T7). I doubt that we have ever recorded birds within. Much of the association appears to be the Salix alaxensis understory trailing out into a bar - then it is heavy with Equisetum + there are scattered S. glauca and S. alaxensis between rocks. But the presence of a thick stand of Dypsis Ascherii, considerable Carex aquatilis, thick patches of Carex membranacea and a stiviparous Poa (aurita?). also Juncus articus and Eriophorum russeolum + wilhelmsia I deduced all of these plants to lie in Vera K's RB3, what she calls Eriophorum - Wilhelmsia.

JP Myers 1977 Vegetation notes : Shrub association S1 Salix glauca / Salix lanata - Polygonum acutiflorum Meade River, N. Slope Borough, Alaska 26 August Transact 7 offers a unique habitat to the transect system, large shrub association, up to 1-8 meters high! of these the 2 major ones (see also Salix alaxensis), S1 in highvalley along the river's edge : 3-4m | [illegible] a b c d e f g h i j k l m n o p q r s t u v w x y z SQ= S1= SB11 B2,8,3 etc see 26 Aug Journal Salix alaxensis S. glauca S. lanata - Polygonum acutiflorum It is a mixture of Salix glauca, Salix lanata as shrub species, very rarely with an alaxensis underlying. Understory: Polygonum acutiflorum (in lower area toward S2); when it is present S1 is called S1a as opposed to S1b (see next), Lupinus arcticus (when present - with Arctostaphylos = S1b) or, Arctostaphylos rubra, an Oxyria, and Dryas. Arctostaphylos becomes very abundant in the upper, drier end of S1. Lupinus appears to replace Polygonum, or rather the Lupinus - Arctostaphylos - Dryas understory became more apparent and prominent as the willow (glauca and lanata) became prostrate. Salix rehmanni also begins to figure as an understory species. Vegetation heights in S1a are higher than S1b, with the willows in S1a reaching 1m occasionally. S1b can be almost prostrate. On occasion the similarity between S1b, in its most deapauperati form, a dune Salix glauca cv/ Arctostaphylos, was disturbing.

J.R. Myers 1977 Vegetation - S2 Salix alaxensis - Equisetum - Polygonum Meade River, N. Slok Borough, Alaska 26 August - amazory. veg heights 2 to 180 cm! see S1 veg. account for position of S1 in relation to river and @ S1. Undustomy strongly limited to a few grammoideae (very sparse), Equisetum, and bare mud. Some Polygonum and Astragalus also present. It amazes me how these willows survive the onslaught of river ice in early June.
