Amerman, Kenneth 1964 6 September 16 - Laysan Island We arrived off Laysan in the USNS "Shearwater" about 7 a.m. and dropped anchor about 0.4 mile off the west shore, in line with the "best landing" site. About 500 Sooty Terns, 1/4 - 1/5 immatures, were flying about the ship, and an estimated 1000 more were visible above the west side of the island. A few Red-tailed Tropicbirds and Fairy Terns flew around briefly. A small number of Red-footed Boobies and Blue-faced Boobies flew past on their way to sea. A few hundred Frigates could be seen over the island and several immatures played king of the roost on the radar mast and boom. Common Noddies, including many immatures were also around the ship - over 100 Sooty Shearwaters were seen before leaving. All the gear was loaded and the raft launched at 9 a.m. We landed at first opposite the former camping areas (Casuarinas) but then decided to set up camp on the northwest corner, where there is only open sand, hoping to avoid the flies. Red-footes in Casuarinas, Laysan Finches and Fairy Terns in Scaevola. Very open grassy area behind Casuarinas contained a few (8) Christmas Islands, Wedgetails and Sooty Terns. Latter not dense at all. Rested a while after setting up camp, then Dick, Alan Young, and I walked around the lagoon for survey while Paul, Doug, and Alan walked the outer beach. A total of ___ Common Noddies were scattered around the whole shore. Estimate 1000+ shorebirds in lagoon, primarily on west side, with Ruddy Trunstones, Golden Plover and Wandering Tattler in ratio of 100: 5: 1. Two Bristle-thighs were seen on the west side and three on thea east, though the latter may have included the former.
Page 63
Amerman, Kenneth 1964 7 Maximum of 500-600 Frigates in air 2-3 times, plus many smaller groups up to 100+. The small groups probably were successive as we went around. No estimate of total. Only __Masked Boobies present. Small (on centration (10 - 12) on east shore. Red-feet generally far into vegetation, nearer outside edge; more numerous on east side. One immature Red-tailed Tropicbird under Scaevola on east side. One Hawaiian Noddy egg, one chick about 4 feet apart in Scaevola. A total of 80+ Laysan Teal, all on east shore. Probably many more in morning glory. Apparently the lack of them on the west side is due to the greater width of unvegetated shore. Returned to camp about 3 p.m. Shortly after this the guys from the raft came by and Bob Banner came struggling up with a surfboard of all things which he'd found in his jaunt around. Other team still not back so I went walking north along the shore. Found Fairy Terns nesting on rocks along the shore; 17 birds, 4 chicks, no eggs. Many Wedgetail burrows under same rocks. Before going on survey Alan and I had gone in to the lagoon, finding about 40 teal. Walked back along beach. Small groups of Sooty Terns (100 or so) along edge of vegetation. One Fairy Tern egg under grass clump. Small groups of Wedgetails, up to 20 and many individuals and plus setting on beach. Dick reports two orange tagged Sooties and one Wedgetail. Returned to camp about 6 p.m. The other team finally returned shortly thereafter. They report about five rocky areas containing Fairy Terns, large Christmas Island chicks and three Bulwer's chicks. No counts on other birds; too far from vegetated areas. Over 200 seals
Page 64
Amerman, Kenneth 1964 (Bob Banner, preceeding them, counted over 200, estimated another 100. Everyone but Paul slept until midnight. He woke us up after banding boobies. Alan and Paul continued after boobies, Dick, Alan and Bob went after Wedgetails and Doug and I walked the shoreline for Fairy Terns and shorebirds. We went north at first to the rocks, then back toward the ship. The shorebirds appear to move out from the lagoon at night, as there are few on the shore during the day. We banded Ruddy Trunstones, Wandering Tattlers, Bristle-thighed Curlews, Christmas Islands, and Fairy Terns, and two Bulwer's. Raft in about 8:30 a.m. Dick and I went after Sooty Terns about 9 while Doug tried the mist nest by the lagoon and Paul and Alan went after more boobies. Finished the 500 Sooties in about four hours. Very few non-flying young. Possibly 1/10 the population from beginning of colony to corner banded. This is perhaps 1/4 of island population. Disturbances every once in a while - birds going for drinks or going to feed? Very few birds barfing fresh squid, only after 11 a.m. Came back to camp ~1 p.m., went for swim. Tried sleeping in afternoon, got rained on. Alan and Bob hauled back two loads of fish balls. Camp now resebles antique shop. Slept again from 9 to 2:30, they went after Wedgetails as Paul and Alan returned from getting boobies. Dick and company went after 500 Sooty Terns. Wedgetails in morning glory along algoon very scarce. Difficult to catch anywhere with moon. Finished 230 by 6 a.m., in same area where we banded Sooties. Found three Bonins, one in morning glory near palms, two in grass (one in burrow, 5 foot long). Wrote up notes at breakfast. Dick had caught a Golden Plover during the night so we had a session of taking photos. Doug and Alan
Page 65
Amerman, Kenneth 1964 and Alan and I began walking west around the island surveying, collecting insects and clocking for ticks and taking photos, about 10 a.m. Insects on the ground relatively scarce - we collected some sow bugs, beetles resembling weevils, tiny ants or termites, some spiders. Flies everywhere in vegetation, though not as bad anywhere as on Lisanski last month. No ticks could be found anywhere. Alan and Doug and Then Alan Young turned back to camp and I continued around the island. Found several (5) Tropicbird chicks under one large clump of Scaevola by the Casuarina that Paul had missed and several more groups and individuals all the way around. Usually 3 - 6 adults in air in an area. One at the southwest end was trying to fly. Groups of Fairy Terns were present on the rocks all the way around. Estimate 300+ for island. They looked minute against the rock wall with the surf crashing behind. Frigates through Scaevola all the way around; many rusty-headed immatures on the southwest corner. Still no estimate. Saw about 150 Red-footes again but must be many more. Masked Boobies in clear areas at other end - 3, 9, 5, and occasional individuals and pairs in grass, plus one group of 5, 2 of which were painted, one open beach. Frigates seen to give way to Red-footes as you move from west to east. Magnificent waves crashing on a rugged fringing rock wall at the opposite end of the island! Grey rocks, looks almost like a gorge coming up on it. Seals bobbing around in the waves. Brown rocks and shelves against the beautiful green water in the east side also very picturesque. Reef close to island all the way around. Beautiful green and red parrotfish. Saw fifteen or so Curlews in the rocky area at the end; estimate at least 100 for island now. One strange shorebird, half size of curlew
Page 66
Amerman, Kenneth 1964 10 but with long thin green-grey legs, 2 inch black bill, nondescript gray resembles yellow-legs in this area also, among turnstones and plovers. Sooty Terns much more numerous than I had thought. Stopped for a while in the area in which we had been banding. Fivehundred adults banded here, very few banded birds seen. Cannot tell if they extend the grass or are concentrated along the periphery. May be as many as 200,000 here, perhaps 500,000 in breeding height. Caught up to Dick and returned to camp (3 p.m.). Swam briefly, then went to sleep after 5 until midnight. Went out after Wedgetails and Bonins. Paul and Alan had found a concentration of the latter in grass between tower and Casuarina. I could find only about 5, they must go underground or under vegetation as night wears on. Did 140 Wedgetails quickly and came back for more about 3 a.m. Alan, Bob, Aland I Finished another 200 by 4:45, came back to camp and slept for two hours. Fairy Tern egg on tower, popped yesterday, hatched sometime after 11 today (September 18). Dick reports one Common Noddy with orange tag. Five returns of Fairy Terns. September 19--Upon awaking, found that the USCG ship "Basswood" was anchored off the island. Waited around camp preparing to go out around the lagoon until 9:30 or 10:00, by which time Bob Fleet appeared with Eugene Kreidler and Ron Walker on their way around the beach censusing seals. Talked briefly with them, then went up to where Doug and Alan were having a very difficult time catching adult Sooty Terns. Headed in toward lagoon, met Bob Long collecting Ipomea specimens in hopes of getting 3 varieties.
Page 67
Amerman, Kenneth 1964 Walked along west shore of lagoon counting shorebirds. Counted 1394 Ruddy Trunstones but this may have included many counted twice; however, probably compensated for by others on outer beach - estimate 1600. Also present - 358 Golden Plover, 132 Wandering Tattler, 8 Sanderling, 3 Bristle-thighed Curlew, one large shorebird, brown-grey, faint eye stripe, long straight bicolored bill (tip black, baral 1/3 orange), long black legs, barred grey and white tail, rump grey, slightly lighter than body. Limosa sp. ? (lapponica ?). Did not appear -go be the same bird I saw yesterday at the south end in the rocks. Cut up through the center of the vegetation on the west side to chick on Sooty Tern distribution. They are not evenly distributed through the Dragrostis, occurring mainly in a continuous band through the more open grass but not to any great extent in the entirely open spaces. This strip appears lighter than the denser, taller grass when viewed from the ridge. Now estimate 60 - 75,000 Sooties, perhaps 1/3 to 2/5 of which are immatures; very few non-flying young. Also found a flock of 750+ Golden Plover in one large open area which apparently was the terminus of the guano digger's railroad according to Ron Walker - tracks still present. Paul estimated the same Golden Plover flock at about 1000. Stopped at the Fish and Wildlife camp and met John Beardsley of University of Hawaii, entomologist. He had just finished walking around the lagoon, sweep-netting. He reports that 180 insect species have been recorded on Laysan. Returned to our camp briefly and then went back to the Fish and Wildlife camp with Paul and Alan Young. After a refreshing swim six of
Page 68
Amerman, Kenneth 1964 12 us set out to census the Laysan Teal, walking through the vegetation about 50 feet apart around the lagoon. We started south on the west side, finding very few. They became more numerous as we passed the palms at the southeast corner. The vegetation also became rougher, with much Scaevola, Solanum and Syparus extending into the Ipomea. About 2/3 of the way around we counted nearly 170 teal on the shore; it was then about 6 p.m. and it appeared that the ducks were coming out of the vegetation to feed. This seemed to be the major portion of the population so we gave up counting and relaxed in appreciation of the right of the birds moving along the shore and in the water in the fading light, bunching up ahead of us. Returned to camp quite tired, slept until 10:30 p.m. Doug and Alan had had to give up after doing 200 Sooties; Doug had returned to the ship in the afternoon, with fish balls, surfboard and driftwood log. Camp now looks pseudoscientific and neat again. Paul and Alan had returned from banding 200+ Bonin Island Petrels and 100 Sooty Terns. Bob Banner returned shortly from doing 200 more Sooties. I went out with 500 Sooty bands and the remainder of the Christmas Island string (29). Banded 200 Sooties, then worked off the 4's. Most of the Christmas Islands were immatures, many with traces of down about the head, and nearly all were sitting on sand just at the annex edge of the outer rim of Scaevola. Found a very few pairs, ran out of Scaevola by the rocks past the Casuarina, finished the bands on the beach. One trio among the rocks, two adults and one half downy young. A few Bulwer present there also.
Page 69
Amerman, Kenneth 1964 In the course of finding the Christmas Islands, ran across a small group of Brown Boobies for the first time - 13 adults, 2 immatures and 3 1/2 grown chicks on nests. Previously I had seen only one adult, one subadult, one immature, all in the air in early morning. Dick had found eight roosting on rocks on the east side. Do not know if they were from the nesting group. Banded 200 more Sooties on the way back to camp. Everyone up, breaking camp by this time. Raft came in at 6:30 a.m., we were on the ship by seven. Raft returned to pick up Fish and Wildlife personnel since the "Basswood" had had to answer a distress call from a fishing sampan grounded on Maro Reef. Underway 8:30 a.m. Laysan - Summary Lyasan is low coral and sand island 1.6 by .8 miles, long axis north to south, with a large central lagoon of salt water. The major portion of the vegetation consists of Scaevola, Eragrostis and Ipomea. There are five major associations: Nama, with Boerhaavia, Portulaca and small Scaevola, along the outer beaches; Scaevola, with Ipomea, indica Boerhaavia and Tribulus, in a rim along the ridge; open Eragrostis, with Nicotiana tabacum, Fibrystillus cymosa, Tribulus and Boerhaavia, on the upper slopes below the Scaevola; Eragrostis - Ipomea, on the lower slopes, denser; and Ipomea - Cyperus - Heliotropum nearest the lagoon The band of vegetation is about twice as wide on the west side as on the east. The Scaevola on the east side is along the shore for the most part reduced to a few clumps and is nearly absent from the north end. The Eragrostis strip on the east is similarly much narrower.
Page 70
Amerman, Kenneth 1964 Some Scaevola patches extend into the Ipomea almost to the lower edge of the vegetation on the east side. Two groves of palms, one at the northwest corner and the other at the southeast corner of the lagoon and one large Casuarina constitute the only land marks. Scaevola forms a secondary line behind the rim on the west side, diminishing toward the south. On the south end the Scaevola is very dense and occupies a broad area. A few Red-footed Boobies and one small colony of Browns are found in the outer rim of Scaevola on the west side. Tropicbirds nest in small concentrations (5-6) under higher, larger clumps on the west and down sides, and in larger groups (20+) under very large clumps on the east side. Most of the Frigates are scattered through the western Scaevola rim. Red-footed Boobies increase. Frigates decrease in Scaevola on the south and east. Masked Boobies found in grass (scattered individuals and pairs from Scaevola to Ipomea) and some concentrations in open areas in grass, around lagoon and on east beach. Wedgetails very numerous in grass, less so in Ipomea, fewest (breeding) on open beaches but glarge clubs scattered over beaches on north, east and south. Christmas Islands - resting under outer Scaevola rim on west; immatures just at inner edge; some in Ipomea on west side, some under rocks on west side, some under rocks on west and north beaches. Bonin Island Petrel most common in dense Eragrostis (no Sooty Terns), many at and under edge of outer Scaevola, few in Open grass among
Page 75
Amerman, Kenneth 1964 19 all along the slope. None on the road or left of transmitter yet. Those in the areas above the transmitter had thinned out by afternoon. Scattered eggs throughout the newly occupied throughout the newly occupied (by day) area, mostly in vegetated rather than open areas. The number of birds on the point decreased by ~50 %, especially in the air. These may have become part of the group in the new area or may have gone to sea. Birds sitting down on road and left of transmitter before dark. February 25 - ~60 Birds on islet during morning. Five eggs in Plot No. 1. February 26 - Two eggs in Plot No. 1. Population on north point has stabilized, no longer moving inward. Many eggs there as well as around plots 1, 2 and 3 and all along above Brown Boobies. February 27 - Population in area of Plot 1 stabilizing - very few birds in air there compared to other areas. Large concentration in air between transmitter, frigates and boobies. February 28 - 18,000± 3,000 sitting during day. 1/4 - 1/3 ? of these eggs. 50,000 present at night. Many eggs on slope north of Brown Boobies. One new egg in plot 1; original five broken. February 29 - Population in area of Plot No. 2. 19 eggs - B 1 plot 4 stabilizing. Many eggs between frigates and shore. March 1 - Birds moving into area between plots 1 and 2 and road to dump. More coming into area on south shore also. 30,000± 5000 sitting by 6:30 p.m. Peal arrival 6:30 - 7:30 - five to six hundred per five minutes - 6 - 7200 1 hour (x 2 ?) Twenty-nine eggs in plot 4. Birds sitting in plot 6. Very few birds come in to north point at night. Three new eggs plot 1.
Page 77
Amerman, Kenneth 1964 21 March 8 - 600 banded on eggs between plot 1 and road to dock. March 9 - Birds solid in former dump areas and to left of transmitter. Only open areas remaining - right of transmitter, both sides of road to transmitter, innermost half of north peninsula. Egg numbers in plots seem to be steadying around 50 except in No. 6. March 10 - Eggs in two new areas - left of transmitter building to edge of road and adjacent to road between plots 1 and 2. Birds sitting to right of transmitter and a few on the road near the building. March 11 - Birds on eggs all the way back to the dock. March 12 - Yesterday the birds were 20 feet away from the antenna enclosure and had eggs to the edge of this line. Today they had filled in another 10 feet but no eggs had appeared yet. March 14 - Birds and eggs right to antenna enclosure. They are advancing slightly down the north side of the causeway also. March 18 - Egg laying seems to have definitely slowed. A few more are laid each day, especially around the transmitter building (some on the road today), but no major influxes have occurred since the birds filled in this area. A few more eggs turn up each day in the study plots; this is probably representative of the situation on most of the island now. The birds moved inward on the north peninsula only about 15 feet more, and slowly; plots No. 6, which was on the edge of the group when it appeared to have stopped and had no eggs. Now has 21. The birds may be moving outward onto the peninsula slowly now.
Page 86
Aerman, Kenneth 1964 March 15 - No. 26 on nest. March 13 - Johnston - fourteen in air, on ground. Four chicks still present. Their voices are exact miniatures of their parents. March 18 - One new nest, total down to twelve now. Four chicks doing well, growing very rapidly. Sixteen to eighteen in air, sixteen on ground. March 19 - One bird which was incubating two eggs last week had one remaining today, with a dead chick beside it. March 28 - Johnston - Seven flying, twelve on ground, three old chicks, three new chicks, three new eggs; banded five birds. Collected one dead chick which had hatched since the 19th. Seven active nests on south side of runway. No adults with two of old chicks. These chicks now more than 1/3 grown (hatched between February 27 and March 5). Upper back feathers and wing feathers appearing. March 20 - 22 - New nest, under Scaevola by powerhouse. ____incubating. March 30 - First chick on Sand - under dock - laid 2/17 : 42 nd day. April 3 - Johnston - Fifteen on ground, three old chicks, two new eggs, four or five small chicks. Many eggs have been broken even though well sheltered. We hope our activities have not attracted attention to the nest sites resulting in disturbance. April 8 - Chick under dock dead. No apparent cause. April 9 - Egg in bunker hatched. April 10 - Johnston Island - Ten adults on ground, only three chicks present (one old, one new), four eggs. We were told that someone took the other two chicks from the PMR area. Eggs are still being lost and apparently some of the habitat is being destroyed still.
Page 95
Amerman, Kenneth 1964 39 been there for some time. We replaced it in the nest. March 9 - Chick dead by nest. March 15 - Total of 267 eggs laid so far in area A, 58 in area B (islet), of which 97 and 6 remain, respectively. March 31 - After not disturbing the birds in Area A for one week 14 eggs were missing or broken (2 of which we removed because they were not being incubated) and 13 new ones had been laid. Most of the losses were in older eggs; only three from 242 on. Probably many more of the old eggs will be lost or will not hatch because they already have been cracked or have gone bad due to not being incubated. Hopefully losses will remain low in the newer ones however. April 9 - Since last check 21 eggs lost, 34 laid, 99 total present. Losses continue to be heavy; 13 of the missing eggs were higher than 242. (Area A) The first week of March 42 eggs were laid (163-204) and 19 lost. Fifty-two were laid the second week (205-256), 31 the third (257-287), and the last (288-309) [March 22-31]. Losses for the same periods were 23, 30, 29, respectively (18 lost March 22-24). April 15 - First chick in Area A - egg No. 129, laid February 17 - 55 ± 2 days incubation. We have decided to check the colony every 5 days now. April 20 - The second chick was found in Area A (main colony) - probably egg 140, laid ___ days incubation. However, while we were checking the rest of the eggs a female swooped down and carried off the first chick, dropping at rear the water's edge, and then another or the same bird got the new chick as well. Both died, apparently from the impact; we took them as specimens. Eggs in Area A and 49 in Area B were pipped.

Amerman, Kenneth 1963 September 11--Message arrived 0800 that Chief Giragosian due today 1100. Did one hundred Sooties 8:30 to 10:50. Giragosian arrived --1030. Ft. Detirck wants one hundred (100 adult sooty terns, 150 shearwaters. After lunch we made up boxes and changed labels from "shearwater" to "sooty terns". Collected the terns in the afternoon, with the aid of McConnaghy and Charly Hill. All the C. G. personnel are really cooperative. They go out of their way to help us. We had enough cartons but not enough waxed inserts or dividers. We made up some more dividers and used a triple thickness of matting to replace the inserts. We began collecting shearwaters about 8:15 p.m., again with Mac and Hill helping, as well as Cuthbert. With this gleeful crew we polished off the 150 in about one hour. The Chief and I then tied up the cartons. "secured" at 2300-- September 12--Chief Giragosian departed Sand Island at 1350, with the bird shipment of one hundred terns, 150 shearwaters. Just prior to his departure a message came in requesting an additional 150 shearwaters for Dugway P. G. He sent a message back (Capt. Reeves, Hawa Sea Fron) tht this was impossible since there are no more boxes here. Camera arrived today, along with letter from S. I., copies of progress reports. Two trunks arrived September 11. Two ammo boxes arrived Sept. 10. September 13--One hundred Sooty immatures. These are harder to catch than adults--t ey will not come near me. Fly away from me when put up, unlike adults. Using disgorged squid from captured adults as bait worked some. Brist
Page 114
Amerman, Kenneth 1963 September 28--Bob and I went on a tour of the island. Two Red-tailed Tropicbirds put on a nice display and nearly landed near the highest are, hovering--about 1 foot off the ground several times. A dead Bristle-thighed Curlew was found along the shore by the old dump. It was in very bad condition, could not be salvaged. This was reported to us by try all. He also claimed to have seen two black and white birds, different from plover or turnstone, by the signal building. He said they flew off toward Johnston. Noddy by 4 foot pipe hatched. Five adult Wedge-tails and several chicks have been found dead over the past few days. We wondered if some might be weakened ones we had released but this does not explain previous ones. New dog responsible? October 1--Sixth Progress Report submitted. October 3--Fourteen frigate chicks color tagged. A new species, tentatively identified as a pectoral sand piper, was spotted by Bob around 9 a.m. and collected by Don Beeson. It was stored in the freezer in the Chief's quarters with a golden plover found dead yesterday. Shorebirds--2 p.m.: Sixteen plover, 14 turnstone, three tattlers. Two dead immature. Sooty Terns were taken to a Mr. Chaigan of the AEC on Johnston for radioactivity content analysis. October 4--Bristle-thighed Curlew reported to us by Winchell. October 5--Curlew reported again, by Dougherty. Again we did not see it. October 7--Began banding shearwaters again with newly arrived bands. One ;hundred nestlings done--very time consuming.
Page 115
Amerman, Kenneth 1965 October 8--One hundred adult shearwaters banded in area between road to dump and both shores. October 9--Two hundred adult Shearwaters banded. Many more found in area covered last night. Second hundred done in area between road to dump and x mitter bldg. A few were found with orange tags but no metal bands. October 10--Two hundred adult shearwaters done in area between road to dump and Xmitter bldg. Several more with tags and no bands found and rebanding. Leg sizes vary a good deal; some of the bands newly put on seemed as if they could slip over the foot. Five hundred adults banded in area of heaviest previous banding. Cannot estimate whether this means overlapping populations or a very large number have slipped their bands and perhaps tags as well. Total population in this area cannot be more than seven hundred to eight hundred. Population seems to fluctuate with cycle of moon. For shearwaters, lowest at time of full moon, then increases again. May merely reflect different time of returning at night--may come in later at night as moon gets higher. Bob suggests may reflect behavior of food organism. Longer feeding time for shearwaters with higher and brighter moon? For Sooty Terns, population had dwindled to -- ten in day, twenty- thirty at night. At time of full moon or just after suddenly they jumped back to about one hundred at night. October 13--Two hundred adult shearwaters banded along left side of causeway and Xmitter bldg. Finding an average of five to six per night (per 200) with tags and no bands. Six frigates banded.
Page 117
Amerman, Kenneth 1963 October 14--Last two hundred adult Wedge-tail bands used, on left of transmitter building and in back of it. Estimate another five hundred to six hundred unbanded adults, 100-200 chicks. Therefore, nineteen hundred banded plus six hundred to eight hundred unbanded and 450 collected gives a total population of 3000± (including chicks). October 15--A semi-palmed plover was seen by Bob on the rocks behind the landing room about 9'a.m. Holmes shot it and we prepared the skin immediately. Another individual of this species was observed by me on October 5, in addition to the one present August 30 - September 1. Bob said that he saw at least sixteen Fairy Terns on Johnston this afternoon and is sure there are several more. This is more than I have ever seen but Binion's original estimate was about fifty. October 17--One Red-tailed tropicbird seen in morning. Twelve frigates banded. October 18--A pintail duck was seen swimming by the seaplane ramp, reported to us by Mc Connaghy. We observed it for a period but did not attempt to collect it. It was later reported swimming toward the other end of the island but we did not see it again. While working in the pump house a wandering tattler (rather aptly named) wandered inside, back out and in again. It was very thin and weak and could not fly, though no wings were broken. We banded it, gave it some fresh water to drink and attempted to release it at the old dock area but it died in the hand. Band was removed and not recorded.

Amerman, Kenneth --Oahu 1963 19 October 25--Popoia Island Fleet, King and myself waded to Popoia from Alala point, --1200 feet offshore. Island is approximately 625 feet by 375 feet. Maximum elevation equals 10 feet (est.). Island is eroded volcanic rock nearly covered by vegetation. Many natural cavities in the rock are utilized as burrows. Thick mats of Portulaca sp. covered about 2/5 of the island. Other main vegetation included unidentified shrubs of two types, one high and one low. No Scaevola was found. This was the most heavily populated island visited so far. Seventy Wedge-tail nestlings were found in the 2/3 of the island which was investigated. There are probably about fifty to seventy more present. A flock of thirty to forty shorebirds was also present, including plovers (10 est.), turnstone (20 to 30) and tattlers (6). As we were leaving the island around 6 p.m. we noticed shearwaters returning for the first time. October 26--Mt. Kaala, Oahu Mike Ord, president of Hawaii Audubon Society, picked up Warren King and me around 9:30 a.m. We attempted to drive up to the puamoho trail but were turned back because of Army maneuvers in the area (live fire exercises). Mike commented that the military seem invariably to choose to overrun areas where the Drepanids seem to be holding their own. As a result, we went about 3000 feet up Mt. Kaala, 2000 feet walking. Even though this was on a new road built for a tracking station, it was very tiring. We managed to see several birds, though none were very abundant, probably due to the recent activity in building the road.
Page 127
Amerman, Kenneth 1963 White-eyes were by far the most abundant. They were everywhere. Many more were heard than seen. This was the only bird not new to me-- I had seen it Wednesday (October 23) here at the hotel. Leiothrix were the next most abundant. I got a fairly good view of one. The red bill and yellow throat really stand out. Elepaio were third in abundance. I saw several of these clearly, adults and immatures (no white on rump). They appeared almost orange-- brown, nutmeg colored. Ama kiki were fairly common. I watched one for some time but it was too distant for me to see the bill clearly. Identify by voice-- catbird-like wheeze. Many more heard than seen. Leiothrix sounds like titmouse with a repetitive call or like an Oriole with a second. A few apapane were present, again more heard than seen. I caught a glimpse of one, merely a flash of red, black and white as it took off. Couldn't see the bill on this one, though I think I made it out (fairly) on one in flight silhouette. Two Chinese thrushes were heard, not seen. October 26--We also went to East Loch (?) of Pearl Harbor. On mud flats there we saw Hawaiian stilts (ten to fifteen), Golden Plovers, Sanderlings, Turnstones, Sharp-tailed Sandpipers, one Dowitcher, Shovellers, American Widgeon (1), both (?) teal, Muscovy duck (2?). In the reeds or cane beyond were flocks of strawberry finches (numerous), rice birds, and manakins (blue bill, black head and throat, brown body). Also present--both doves, mynahs, one coot.

Amerman, Kenneth--Sand I. Midway Atoll--Green I., Kure Atoll 1965 24 owl, redhead duck, unidentified duck resembling small scaup (Asiatic?), several sharp-tailed sandpipers, one pectoral, several unidentified uncollected passerines. Two mist nets have produced about twenty shorebirds in two days. Saw my first Masked Booby and Bonin Island Petrel today--latter from mist net. Unident. Procellarids on Midway most probably Bonins. October 31--Jim and Bill took me on a short tour of the study areas. Seventy-three burrows in one corner (50 feet by 50 feet) of one plot. We then rode around the beach on the flatbed, chauffeured by Gibson. Saw my first albatrosses, Black feet. We banded five. Also saw my first Hawaiian Monk Seals - one group of twelve, another pair and another single. Three new ones were tagged. Shorebirds caught in mist nets are being weighed and measured. Jim has demonstrated the preparation of both skins and skeletons. November 1--Jim and I spent the morning and part of the afternoon plotting one shearwater-petrel study grid and counting burrows. The birds seem to favor the grass clumps or grass-puncture vine associations. They seem to avoid low puncture-vine, but a few are found beneath high columns. A few are found beneath the clumps of another low-growing, 1 light-green plant. Very few were found in Scaevola. 333 active burrows, 151 inactive, 82 scrapes, average density per slot = 35. Maximum 84 and minimum 8. Later in the afternoon we rode around looking for seals and gooneys. Four new seals were tagged, new black-footed albatrosses banded, __ new recoveries. We also missed unbanded birds, making a total of __ new birds for the day and __ altogether on the island.
Page 130
Amerman, Kenneth--Green I., Kure Atoll 1963 At night we tried some banding but it was still too bright, even though cloudy. 38 total One ? frigate upchucked three 2 1/2 inches file fish - first reef fish I have seen as food. November 2--Saw only previously handled albatrosses on tour of island today. November 3--I skinned a common noddv in the afternoon. Abominable amount of time to do a fair job at best. Long way to go. Four new albatrosses. November 4--Up early for a day of observations from north tower. Worked at this from 0800 - 1150 and 1320-1630. Jim was simultaneously observing south end of island from radar tower while Bill checked his traps. Some general notes on activities after one day of observing--no Fairy Terns seen in afternoon: only one noddv seen in early afternoon, then several late (1500). A few frigates were seen soaring over lagoon late in morning; always several in afternoon until - 1600 when activity dropped off. Very little activity from 1300-1500 except frigates and occasional booby, then picked up past this hottest part of day. Much preening all day during molt. Went out after dark after albatross. Got first Laysan, on west beach south of dock, plus largest number of new individuals--over forty. Also got several frigates, ten red-footed boobies. November 5--Jim and I switched places for another day of observations. Saw about thirty albatross along the beach all day--five just below tower. A pair seemed to be formed early in day when one marked individual replaced an unmarked one after a brief encounter. The pair engaged in kill
Page 132
Amerman, Kenneth 1963 Weather prevented note taking in A. M. General observations-- albatross flying in close all day; always one to four in air. Frigates-- very little activity, never more than two to three in air at once, mostly just flying around the roost area. Boobies--wind appeared to knock some from their perches, as one or two would get up just as a strong gust passed by. Shorebirds in bushes and interior areas all day, some noted flying around over the island. Much nodd activity low over the vegetation; one large feeding flock of 60+ individuals plus another 60+ scattered individuals passed by about 9:45 a.m. Hardly any on shore all day. Possibly one tropicbird seen far out over the south end, heading east. Two seals went cavorting by, 1005. November 8--After debating whether to put in some more time on the towers, Bill and I banded from 1030 to 1230 and from 1330 to 1700. Got 172 albatross over 100 of them new bands, rest recoveries. Laysans have suddenly appeared in numbers, and in the interior parts of the island, between the runway and beaches. Also saw many seals up in the edges of the vegetation on the north and east sides; many untagged. Appeared very sluggish. Occasional sprinkles, high winds. November 9--Arose late after heavy date last night. We went out banding gooneys again, 1600-1700. Laysan's in in even greater numbers; some now in antenna field and two behind barracks. We got about forty new birds, getting nearly 100 % along the west beach and in the interior, missing

Amerman, Kenneth 1963 November 11--Cleaned up the lab in a mad rush about 9 a.m. since a plane was due and it was suspected the Western Area team might be on it (on day early). We finished with only seconds to spare, just in time to see the plane turn back to Midway, unable to land because of trouble with the landing gear. A few moments of tense drama on an island paradise. November 12--Inspection team arrived about 1000, left about 1530. They seemed rather concerned about the rats, more than anything. Jim went back on the plane to have his head and thumb looked at. He rather ingloriously smashed into a shutter chasing rats; this didn't satisfy his masochistic impulses so he sliced his thumb with a scalpel. We gave him enough errands to run to keep him from getting too drunk. Spotted a small teal in the puddle by the fuel tanks and tried to take it whole without success, couldn't spot it again. Banded one Golden Plover from net, four Bonin Petrels. November 13--Bill and I banded albatross all day on the north half of the island, concentrating on the Laysans in the rat study area and antenna fields. We got about 150 new birds. Locations were noted in the study area. Many of the Laysans were sitting on apparent nests and were slow to get off. Many are making the "talking to chick" noises, even those not on or near apparent nests. We saw one pair copulating in the field behind the volley ball court in the afternoon. Found an unbanded brown booby sitting on two eggs in an old road in the northwest sector of the island.
Page 136
Amerman, Kenneth 1965 31 November 16--Albatross banding in afternoon. We handled about 260 birds, with the aid of Silock and Gibson. Worked south along runway-- East side, and south antenna field. November 17--Began clearing vegetation plots in afternoon. Nearly finished one in morning glory on west side of runway, south of buildings. Completed another in grass at north end of runway and started a third, in mixed Vegetation, along the shore at the same area. Bill and I banded seventy Laysans and got twenty-nine recoveries behind barracks and in south antenna field before dark. Jim began setting up albatross study nests. November 18--Bill and I ran the traplines. Weighing each individual in the wind was a real chore. It took us all day. We managed to finish just in time to reset the traps for tomorrow. 131 captures. November 19--Second day of trapping. 139 captures. A great many Laysan albatross now in the study area and the rest of the antenna field, most of them unbanded, which is disheartening. We have given up all hope of keeping up with them as they arrive on the island. Many are in pairs now and there is a great deal of the "talking to the chick" calling. So far we have seen very little dancing; what displays we have observed have all been short. We discovered that most of our ticks have died, which means a great nuisance for us in catching rats and searching them all over again. We caught and killed sixty-three rats this evening and tallied over hundred three ticks from them. They had better remain alive and there had better be a plane Thursday!
Page 137
Amerman, Kenneth 1963 November 20--Third day of trapping. 143 captures, one of them a triple again. The weather was much more cooperative today. Very little breeze. We finished about 2:30 and then decided to put metal tags on the end stakes. Finished only the "one" end before time to reset the traps. Took in the movie for a change--very good, too, surprisingly. I took a walk up to the south point after supper and found the first Laysan with an egg, just behind a Scaevola clump off the runway at the south end (east side). This was the first time since Staurday I had been along the beach. Many black-feet have eggs now and the whole picture has changed. Most of the individuals remain sitting, even those not on eggs. November 21--Bill and I finished trapping in good time, before lunch and hauled the traps back to be cleaned. Jim's thumb has been acting up again so he has elected to go to Midway with Bill to get the house over. Just as they were getting ready word arrived that there would be no plane! The prospect of not being able to get the ticks out caused no end of muttering and rumbling. Bill fired off a message to KebSchull explaining the situation, to the effect that the ticks had to get out on the Friday log flight to meet personal pickup (by Bushman, who talked to Jim on the ham gear in the morning) in Honolulu. Whether this had any effect we of course don't know, but we got a plane at 5 p.m. November 22--Rain and high wind most of day prevented working out of doors. Of course the station was buzzing over the shocking news of the President's assassination. Fiddled around most of day discussing this and listening to news. Could not find Jim's birds from Midway in the refrig.

Amerman, Kenneth 1963 December 5--Continued work on albatross recoveries, covering the west side of the runway below the barracks and the entire east side. With few exceptions unpainted birds in the southern and eastern portions of the island are now unbanded ones. This makes the record keeping somewhat easier. Totals for the day: nine black-feet, four of which were incubating, and 153 Laysans, 110 on eggs. Roger Clapp arrived on the afternoon flight. We toured the beach from the dock to the north end of the runway before supper. December 6--Roger and I worked all day on vegetation plots, mapping Nos 1, 2, 4, and 1/5 of No. 3. Measurements are very subjective and variable, probably non-repeatable. Much difficulty in deciding what to measure (which plants and which parts of plants), especially in areas with much young grass. At Roger's suggestion we went through the north antenna field recording all Masked Booby bands. This is a good idea for several reasons-- any new individuals in the population can be recorded; it gives an accurate picture of numbers present and of sex composition; the birds are marked for further study. Males were painted with a stripe across the head, females with a spot, and unknowns with a central stripe. This procedure should probably be repeated every three months. The results of the evening's work are as follows: two new bands (737-47001, A-U, and 47002, A-F); 101 recoveries (13 juvenile, 40 ♂, 37 ♀, 11 U). Roger remarked about the birds' reluctance to vocalize, at least in the hand, which led to the high number of unidentifiable birds.
Page 143
Amerman, Kenneth 1963 Two groups of three tropicbirds were observed in early afternoon and a seventh individual was reported by one of the M and R crew. December 11--Dr. Fisher and Dr. Pettingill arrived on log flight about 8:30. We set to work capturing two small live seals which Cr. Fisher was procuring for the Honolulu Aquarium. This task was accomplished by 10:30. One individual was taken off the south point and another at the southern end of the Scaevola on the east side of the runway. They were left in the cages by the road to the barracks until the plane returned. While capturing the seals we observed an unusual large (yellow-legs size) shorebirds by the dump. It was long-legged and long-necked, unmarked gray except for slight white V on rump. Roger went to collect it before lunch, returned resembling a Cheshire cat. Further notes - legs gray or slight greenish gray, bill black and as long as head; weight - 180 gms. Spent the rest of the day finishing records and running around like a maniac collecting gear for departure. Departed Green Island, Kure Atoll, at 5 p.m. aboard log flight with Drs. Fisher and Pettingill and seals (phew!). The seal taken from the south point had died suddenly between 4 and 5 p.m. We transported it to Midway and Jim and I autopsied it after supper. Seemed to have blood in chest cavity, but not nearly as much as first seal we killed. Jim believed the intestine was ruptured also. Left the skin to soak and went looking for ducks on puddles in overrun. Scared up one pintail (?) and three teal-sized individuals but were unable to get them with lights alone.

K. Amerman 1966 Sand - Johnston January 17. Departed Honolulu 0500 via M475 N-23. Arrived Johnston 1100. Chicked at Terminal, no one knew anything about bird shipment except that there definitely was no flight Wednesday or Thursday, huggcd my gear to the boat dock by hand and arrived on Sand about 1230. Mage knew nothing of shipment. Called George Sung in N.Y.N shipping; he said we could put birds on flight tomorrow. We went to J.I. on 430 boat, got 30 cartons (albatross rig?), absorbent material and unmarked cardboard bottoms; 10 liners. Returned to Sand on 730 boat. Began catching birds about 10 P.M. after assembling a few boxes. Catching went well so we made up the rest. Finished catching & boxing about 0100, labeled them, punched air holes and got through about 230. We ran out of tape after doing all the bottoms, just folded the tops together. Caught a total of 58, 2 per box. The last few took us through the entire colony, all birds in air. About 20 eggs; one new chick on bunker by inlet. Males were much more numerous than females. Tried to call Dr. Ely about 2000 before beginning our labors. Honolulu operator and Pearl Harbor operator got recordings signifying non- working party no. when they dialed 39103. So far it has not proved an auspicious start. K. Amerman 1966 Sand - Johnston January 18. Up at 0715, nothing to do but watch the morning's proceedings until about 0815. Birds taken to Johnston by 0900. Warehouse people most cooperative; gave us tape for the tops of the cartons though they might have been shipped just folded. All birds were alive yet. No banded ones had been taken. Returned to Sand on 1100 boat. Rested until about 1400 after lunch. Then to colony to pick up guy wire casualties and autopsy. Casualties centralized in area C, southern 1/3 of areas B+D (Crop. alms south shore) and western side of area E. No Scotties examined had brood patches. Males had testes averaging about 11 for left, 6 for right; females' ovaries about 12x5, ova 2-3. Sex ratio nearly 1:1. Estimate 150+ total collected; 24 autopsied; 15 bands recovered. Frigates did not seem much disturbed by last night's raid. Males are definitely more numerous, actively courting. Entire nesting colony has shifted from hill to south shore rocks except for a few on the inlet. Perhaps this was the original site and was disturbed by Coast Guard activities before we arrived. One Red-foot beginning a nest, on the north shore site. No Brown's nesting. Some Noddies with 2-3 on peninsula and east shore. Saw 11 Fairy Terns on Johnston yesterday.
Page 225
R. G. Newman 1966 Sand-Johnston January 19 We collected Sooties and autopsied in The morning. Total of 65 dead or badly injured, plus 2 Common Noddies. Autopsied 13, none with blood patches, 3 molting (2 at least) each. One tail feather each. Found one Blue-faced Booby on guywire base #7. With the exception of 2 imm-5A at 1900, no Browns even sitting on the hill in morning or evening. Afternoon spent on task work. Checked the other end and collected Belizees 1900. Banded from 2030-0030, total of 400+ first hundred checked for blood patches (0) and molt (2 at 1 outer reticul). No Graybacks nesting yet. They are on the islet and pier and a few were on the rocks above The pier after dark. Returned me Hawaiian Noddy while banding. Total of 7 Blue-faced on #7 1900. About 150 adult frigate in nesting colony, many immatures sitting around periphery. Sooties begin to mass offshore about 1600. They form two swirls, one off north side, other off south. They do not come in over island until about 1900, funneling in from west but not flying much over the causeway except for streaming across it earlier. First birds alighting about 1915, low in area D about 1/3 the way from the road. There seem to be Two Groups of birds, some swirling fairly close + streaming back & forth over island; others are R. G. Newman 1966 Sand-Johnston January 19 far out and in greater numbers, apparently do not come in to land as early as the former group. Perhaps latter are the first arrivals, which now form a cohesive unit after perhaps having built up to a number which could trigger a new phase of behavior. There was no moon while we were out and the birds seemed to be holding rather well. Also, they are down over a large area, including area 13 and area D between roads shore. January 20 Same routine as yesterday. Only 3-4 Blue-faced present on #6 guywire base in A.M. Banding 2030-0015, Total 500 Sooties. We worked the east side of the Xmitter building, found the birds much more edgy than on south; finished on South. Saw two Sooties standing on dead ones, either outbacking or attempting copulation. January 21 Hourly counts on Sooties & Frigates today. Summary: Redfots decrease sharply right around sunrise, remain fairly constant thereafter until evening influx between 5-7, though much shifting around was noticed from about 4 P.M., Browns concentrated on hill until about 8, then drop off until 1200, then remain steady until 1500, mainly on guywire bases & pilings; increase again between 4-5 P.M., coming back to the hill until 6, then moving back out to platforms & bases, almost exclusively immatures in colony site during the day. Some bill-fencing noted in 9 P.M.

Y. Amerman 1966 Sand. Johnston Jan 21 (crnt) Blue faced Booby - 4 on #6 at start, 2 most 8 day after; a third appeared about 1600, Sat on slate for a period, Then moved to rocks among frisate, for 1/2 hour. All active around 1600, jumping off into water, flying short distances. Great Frigate - Similar to Red feet: decrease from ampic to H, then incito. Then constant until 4-5, increase again. Colony about constant all day. Immatures sit in two groups; at E edge of colony and between two segments of it. Witnessed two copulations (or attempts), much courtship. Sometimes, evidently, when the pair bond has been established, when The partner alights beside the other They fence bills briefly and shake heads mutually. This also occurs when F brings nest material. Female accepts, places, them may fly off leaving male to finish incorporating it into the nest; several males busy with nest while females gone. Saw two adult & frisates land among 7 immatures on hill 1540. One & fed two chicks, The young going inside her bill to get the food; evidently not a whole fish regurgitated; both bills level, so food, if liquid, still wasn't "poured" into young. Grayback Tern - 0800 0900 1100 1300-1820 1900: 175 175 40 104 Dick found first egg today, 7 on pier + 1 on islet. 500 Sooties banded. Y. Amerman 1966 Sand - Johnston January 22 Sooty Tern mortality only about 1/2 what it has been previous days. Perhaps This was due to lighter winds last night, or fewer birds being present? Checked pier, one new Gray back egg (total 8). Surveyed Johnston between 1700-1900. Found 2 new Tropic bird nests with eggs plus the older one. No other birds seen flying. No Fairy Terns seen. Only 6 plovers, 20 Turnstone, 2 Rattles and one Sanderling seen. Banded 100 Sooty Terns, checking for molt & brood patches. Three of mine were molting around 11-14th secondaries only. No brood patches get anywhere on island. Worked returns after this - they were much scarcer than last night. The numbers already banded is remarkably low, from observation. January 23 The first Christmas Islands appeared - a pair sitting by the large slab on the east shore at the base of the peninsula. Returned one. (1300). One present at night? on slope. Gray backs beginning to lay on west edge of peninsula near tip - 3 eggs, one broken. Eggs on pier now total 13 3 + 1 on ischo by pier. One of the two Common Noddy eggs on The peninsula hatched. Total of 500 Sooties banded. January 24 Total of 35 Sooties collected from papyrines. Red footed Booby nest on north shore has disappeared. Probably 100-150 Common Noddies nesting on peninsula and grass along east side - 17 banded.
