DuVal, E.H. 1999 Journal San Jose to Wilson Botanical Garden, Costa Rica 6 June 1999 Bus to the Wilson Botanical Gardens/ Las Cruces Biological Station, courtesy of OET/OTS. I was going anyway, so I had a free ride. My field notes from Monteverde and my poncho are officially lost - perhaps the notes were accidentally packed with Rob Clay's luggage? Las Cruces is gorgeous. An undergrad course based out of Duke is here, and one of the professors has ties with Mercedes Foster (same study area, etc.) and offered to answer any last-minute Peru questions if I go. His info: Donald Brightsmith 116 Stedwick Pl. Durham, NC 27712 USA (919) 471-0464 email: DSBY @ DUKE.EDU 6 June 1999 Met Deedra McCleam and company (David, Victor, & [illegible]) at breakfast, and was offered a ride to Las Alturas. Victor accompanied me to San Vito to buy groceries and a machete before the trip.

Duval, E.H. 1999 Journal Las Alturas, Costa Rica June 1999 Monitored nets with Catherine Lindberg (Mich. State U.) and her research crew in the Las Alturas coffee fields, to get a better idea of the birds here and to practice removing birds from the nets. Nets were placed along a stream and up side paths into the coffee fields. Note: Look up the Handbook of Field Methods for Monitoring Landbirds, published by Pacific SW Research Station; P.O. Box 245; Berkeley, CA 94701-0245 phone (510) 559-6300. May 1973 Ralph, C.J.; Geupel, G.R.; Pyle, P.; Martin, T.E., DeSante DF.

DuVal, E.H. 1999 Journal Isla Boca Brava, Chiriqui Prov. Panama [1] June caid] site: Isla Boca Brava weather: clear all day, some clouds, no rain Notes: It is difficult to explain to Frank Kohler the magnitude of what I'd like to do here. I'm trying not to blurt it all out at once or start plotting the housing for field assistants without letting them get to know me a bit, first. The island is beautiful, and teeming with lance-tailed manakins. Frank initially said that he had no C. lanceolata here, but his wife disagreed. On a quick walk around part of the island, I saw no fewer than 10 manakins. (much better than in Monteverde, where they seem to have gotten people-shy. I hope getting them doesn't result in the same shyness here. I saw ~4 definitive males, 1 immature male, and 5-7 females/ juveniles. I also heard many different calls and observed

Notes: The "toledo" equivalent is much less regular than that of the long-tailed manakin and always ends with a high-pitched "pip!" The dancing song has a rattle to it not heard in the long-tailed song. I also observed 2 males flying back & forth between two perches (x calling at each perch - the "pip" noise? I don't remember...). The females were directly on the display perch. The longer-visiting ♀ was in a head-down posture (soliciting?) I had a clear view but tried getting closer & the males moved to a nearby (but not visible) site. As I listened, they moved again.

A good place to set my nets... 5) bridge across a creek at this point; 2 males clearly visible to the west of the bridge, displaying (though they stopped when I approached). Another lek could be heard to the east of the site. * other sites where a lek was heard. Assuming 2 DM per lek, this implies that there are at least 22 males displaying in the area. Not bad... Other sightings: barred antshrike pair, brown pelicans x ~5 Magnificent Frigatebirds from the restaurant. ~4 members:

DuVal, E.H. Journal 3 July 1972 Isla Boca Brava, Chiriguí Prov., Panamá Frank told me last night that they found a nest with 2 chicks while cutting laurel trees ~ 3-4 weeks ago near the 2nd landing. I set off today and found the empty nest - a bit large, but otherwise perfectly manakinish. The site is at the back of a clearing, 200 paces after the bridge near Manuel's house (you can see the house from the road at this point). Perhaps shell renest in the area next year?

DuVal, E.H. 1999 47 Journal 8 July 1997 Isla Boca Brava, Chiriqui Prov., Panama Hike: notes Generally the manakins are much quieter than when I first got here. Only one dancing lek was heard en route to John's property. * Location: Just below the cleared lots to the ocean side. Saw 1 DM & 1 ?. A definite potential netting site. NOTE: My liquid N2 is low lately (?!) May need to buy a little more in David soon. In the cleared lots area: ocean rancho truck tree line wire Saw DM & RCM in trees. RCM approached DM with begging call & [illegible] DM did the "grow" call and left. Also

Also 3 blk & red tanagers (scarlet - rumped?) in John's field. ? manakin eating berries. DM + RCM both sunning self on branches with wings spread. Heard 3 manakins near the cabaña this morning - 2 were green-phase (I was warbling, both pip & (chip?) calls). Didn't see either. Several new, promising lek locales today: 1) below the cleared lots 2) at the crossing of power lines near the track 3) On John's land, near the rocky beach (perhaps several territories in one area?) 4) At the well near the old horse field, where the power lines end. 5) near the bridge (confirmed perch) 6) by the 2o beach, just up the gully from beach

DuVal, E.H. 1999 49 Journal Isla Boca Brava, Chiriqui Prov., Panama I have found fresh burrows w/ worn trails leading to them at the tree area of bee tree lek & near the second beach lek. What lives there? Saw 2 black iguanas on the rocks of the first beach. They sheltered under an overhang, just around the point of rocks toward the second beach. Manuel was working with his brother Franklin, & as they walked home they stopped to talk birds. Franklin mumbles, but I have no problem understanding Manuel. They both used the binocs. Manuel asked how much they cost, & I just said "mucho." No further questions. Manuel spotted 2 ? and checked for birds (none). I think he would be a great field assistant if we could communicate. variegatorides melanina Saw a blk. squirrel w/ rufus sides - color of a manthed howler. Variegated squirrel

R cap brighter possibly bigger blue back sl. darker bird bulkier-looking? Centr. w/ Monteverde Diff habitats, density diff huge in Monteverde ~ 80 males, 80 hectares Nesting habits - no suggestion of communal nesting Reasons to be together - not a great abundance of fruiting trees; ? pop in disturbed area; tree height Wah vs. Wa - assech in long-tailed Variation betw. calls in longtails.

Note: At the well site, in the split of a fallen (heliconia-like plant) leaf there is a pile of spit- like bubbles teeming with little tadpoles. Darker dorsal area, speckled head, very small. What type of frog is this? Bubble nest ~5.5" long, single tadpole, 5cm Rogui says: some Leptodactylids build foam nests like this.

DuVal, E.H. 1999 59 Journal Isla Boca Brava, Chiriquí Prov., Panamá July 1999 Site: Isla Boca Brava, Well site 2 Weather: Very humid! Net hrs: Opened 8:00 am Closed 1:00 pm nets 1-4 used, same placement as on 7/11/99 total: 12.5 hrs Habitat: Since Sunday, Franklin's workers have "cleaned" the area - the paths have been further cleared of heliconia + saplings Notes: Other dancing perch heard across the path from the one observed on 7/11. See map from 7/11 From the field notes: "SHIT. Manuel just told me that while I was gone he & Franklin opened the nets and caught 2 manakins. He said they kept them in their house for two days, the birds weren't eating, and they let them go. Manuel is way too smart for his own good. I asked him not to use the nets without me, explained that Richard, who had studied birds for many years had killed 2, & I don't know if any will sink in. I don't want to get M in trouble, but there are so many reasons why only I should use the net!"

(North, South trails, & "Main Street" We walked up the North trail first, stopping to watch activity at Bee Tree. A surprising # of birds observed were banded. At Bee Tree I observed (DR) YO/Rd, RY/Ral (on), & BY/Bal (rc). The males are definitely displaying! I took the South Trail & saw YR/Pal (RC), who led a chorus of manatins who alarm-called at me from a display site near the second beach. I Saw a nightjar and two Little hermit hummingbirds in my wanderings... I attempted a list of vocalizations that we could make into a code for use in observations. I tried having us record 3-min bouts of behavior but even I couldn't do it.

Apparently the island across from the point has plenty of LTM's as well: perhaps I could go there for a comparison with "cleaned" land behavior? Certainly I should net there to see if the populations are mixing? What questions could I answer with only one year of data?

DuVal, E.H. 2006 14 March 2000 Journal 14 March 2000 Isk Boca Brava Mistnetting at the "bridge" site: we centered our nets on a lek just North of the bridge. As we set nets, we observed 2 males dancing for >1 min. very near the trail. It was a very good day for netting - we caught 12 manakins, many of which were Black Faced or DM. Other captures were 2 red-legged honeycreepers (male & female), 4 ? lesser seed finches, 2 rufus-tailed hummingbirds, 1 barred antshrike, + 1 northern waterthrush. The manakins: DM IIII =3 CB IIIII =4 BF I = 1 RC II = 2 G II = 2 Both G's were adults, & presumably female: one had the beginnings of a brood patch. I looked for the darker eye streak I had noticed in the long-tailed manakin specimens in the MVZ, but couldn't find one. I did see one RC male who had

14 March 2000 Journal Isla Boca Brava, Chiriqui Prov., Panama tail feathers that seem to be juvenile morphology (#79): more symmetrical, broader, We took a break at midday for lunch & to wait for the cooler afternoon. I walked back to spin down plasma samples & stopped to watch 2 DM's dancing across from acacia near the main street path. Moved off as I approached. Thought for the day: how would you know if manakins were lekking? Requires male aggregation, female choice, (no paternal care), non-resource-based, +... It seemed like several pairs of males were displaying within a relatively small area near the second beach - could Dave McDonald be right about perches within earshot constituting a lek? I talked with Frank about money last night, and he

Duval E. H. 2000 14 March 2000 Journal Isla Boca Brava, Chiriqui Prov., Panama gave us a reasonable price (though our ranches are falling down): $10.00 a night for both. He also graciously pointed out that I could rent a house in Boca Chica for $30 a month. Savings of $250/month plus the chance to mix with locals sounds good to me. The field assistants visibly balked at the idea, even for short-term, though they saw next to nothing of Boca Chica. Plus Insisting that it would be more dangerous since we wouldn't know any of our neighbors. Why wouldn't we? Sounds like a good reason to get to know people...

DoVal, E.H. 2000 15 March 2000 Journal Isla Boca Brava, Chiriqui Prov., Panama March 2000 We continued netting at the bridge site, and closed the nets after catching AI #103 AI #95 hit the first net when it was in the late morning sun, and was dead by the time we found him. We caught 17 birds in all. DM III = 8 new RC I = 1 new Gorsl.T II = 7 new BF I = 1 recapture I taught Mark & Kat how to prepare hormone samples, and then skinned #95. He's got an unfortunate tear in the skin of his neck (& back), and when I went to seal his mouth shut with a drop of superglue the cheap Ashby Fleamarket stuff spilled all down the feathers of his cheek. I tried ethanol to remove it, and only succeeded in making it white. I collected tissue in ETOH and froze it, including syrinx and his LARE testes. Definitely a breeding male... A Caluromys possum has electrocuted itself on the power line just above the hostel: its teeth are locked around one wire & its tail wound around another.

Eileen agreed to send supplies, though I'm not sure exactly what she'll be able to mail due to customs regulations. My requests were written in excited, rambling style, so I'll have to see what she get from it. She says I was a finalist for the Beim Fellowship but didn't get it, and that I'll probably get $4000 from the Integrative Biology departmental fellowships. No word from the other grants yet. Tyrone Hayes answered my questions about sample purity by saying only that he would use a different needle for each sample, not what the consequences of my present predicament would be. I have only 8 or so insulin syringes, so I've been using one for all the samples, rinsing 3x with DDH2O inbetween samples. I'm not quite sure what to do...

Dullal, E.

Plasma samples are frozen in liquid N2 immediately after separation. The clay plug in the capillary tube's bottom is pierced with the same needle used to draw blood from the bird, and the red cells are blown out into two separate vials with Longmire's Solution (LMS). One vial is stored in liquid N2, the other at ambient temperatures.

We captured WAG, the female who is brooding on nest E-1. It was a good day for target netting, despite my butterfingers. I checked nest E-2, and there are still no chicks/eggs, though the nest looks very complete. Perhaps a predator has already emptied the nest or it was an early clutch? Mark has reported seeing fledglings near Bee-tree.

Du Val, E. H. 2000 Journal 7 April 2000 Isla Boca Brava, Chiriqui Prov., Panama Notes on display: Slow flight is performed by one or two birds - usually two after a QR bout & before or after dancing; by one bird after the partner leaves & the remaining male is finishing the courtship. Males fly with neck outstretched, head slightly down, and crown flared, fluttering laboriously between perches and frequently passing close to the female. Male(s) often give a "pip" call when landing and quickly leave the perch they have arrived at. In dual display, the first male usually "pip's" on arrival, and both give a coordinated down-whistle when the second male lands nearby. In solo slow flight today (at well) I observed for the first time a rattling noise that was only sometimes heard as the male passed the female. (Other passes were silent). It was the faint fast click of a bat hunting or a heliconia bowing in the wind. Perhaps this is one of the mechanical mating sounds?

DVal, E.H. 2000 Journal Isla Boca Brava, Chiriqui, Panama 7 Apr can't To my knowledge, no mechanical sounds have previously been reported in the display of lance-tailed manakins.

Duval, E. H. 2000 Journal Isla Boca Brava, Chiriqui Prov., Panama April 2000 We spent the day doing observations at 9 display perches. There are many Swainsons Thrushes in the area, calling, fighting, and flitting part like manakins during observations. During my last watch at Acacia, a bird walked up to me (4 away) that looked like a Northern Waterthrush or Ovenbird, but didn't have the center orange crown of an ovenbird, and had distinct black stripes (3-4) on the top of the head, unlike N. or Louisiana waterthrush. Legs were pink and long, breast was white (not buff) and spotted with nearly circular pattern. Throat white, back & head brown (except for the stripes) Notes on nests: Stiles & Skutch A Guide to the Birds of Costa Rica lists the incubation time of manakins as 18-21 days, and with an additional 13-20 days in the nest for the young.

DuVal E.H. 2000 Journal Isla Boca Brava, Chiriqui Prov., Panama 8 Apr cont For the lance-tailed manakin, Stiles & Skutch say: "Nest: A small, shallow cup of grass and leaf fibers, slung between the two branches of a low, horizontal forked twig. Eggs usually 2, buffy with reddish-brown spotty, mainly in a wreath around large end. August - September (in Panama: no Costa Rican record)." Our work already contradicts this, as lance-taileds are clearly nesting in April... The nest is an open cup made of plant fibers & fastened to the fork of a sapling or small tree with cobwebs. Dead leaves are hung on the outside of the cup. 2 eggs, as described. We have noted a few peculiar things about the 12 nests found so far: Nest E-4 was found with one egg and one chick (probably 2-4 days old, says Kat). When the nest was

There is no sign of the egg below the nest. What predator would have eaten the egg and not the chick? It seems like the egg would have to be removed by the chick or the mother. Is it possible that a brood parasite bird targets manakins? Nest K-1 has 2 eggs, but one is noticeably larger and whiter than the other. I'm not sure how much within clutch variation there is. Nest E-3 has an egg with a tiny hole in it, and there was an art on the shell. Either something broke into the shell, or the chick is hatching now. Both white-tipped dove nests that I have found have housed 1 egg & one nestling. The dove nest at bee tree has recently fledged

The contents more freely (ie no anchoring membrane?) Inside was an embryo, 8.4mm x 9.8mm with an eyespot ~ 1.5mm in diameter. There was no distinct yolk & the "white" of the egg was a milky pink color. I'm not sure why it failed or if it truly had. The abandoned egg from the nest near EDA, was broken & on the ground, with the (dead?) bodies of many small ants in it. On 11 April I found only a chick in nest E-7, which had been found on 10 April with one chick and one egg. I located the egg in the leaf litter below the nest and cracked it into a vial for storage in liquid N2. There was no embryo visible. The eggshell was folded into another vial and also frozen. As of 15 April, we've still been unable to identify the female associated with this nest.

I was at Bee Tree, which I really think we should try watching at all perches simultaneously - the birds just move perches when observed. I found one new nest under construction, & noticed that E-3 was completely unattached on one side, leaving the 12-day old baby JUST about to fall [illegible] out. Against my evolutionary upbringing, I reinforced the nest with guy line so that it would hold the baby until fledging (after all, I may have weakened the spiderwebs supports as I scooped out the baby to take blood...). While staking out nest E-2, which now has 2 chicks, I saw a male black-hooded oriole perched a few feet above the nest. He cocked his head several times, looking at the nest, and was flying down to a lower perch by the nest when a female manakin mobbed him and drove him away. It's

D'Val, E.H. 2000 Journal Isla Boca Brava, Chiriqui, Panama not conclusive evidence, but suggests that antshrikes may be nest predators of manakins. There are certainly enough of them on the island to pose a threat to nest success! I didn't see the female's bands (or lack thereof).

AYP) left, and AYY continued to do the solo slow flight, with the faint wing rattle that I first observed at the well site. The female jumped rapidly back and forth on the dp, & sometimes followed the male as he flew past the dp. AYP frequently broke off his slow flight to chase an unb RC that kept approaching the perch. AYP mated w/ the unb G, who stayed on the dp & raised her tail, held forward. This lasted a few seconds, & then AYP broke it off to chase the RC. ? remained on dp & didn't preen as usual after copulation. AYY resumed slow flight, but eventually the ? left. She may have returned later, as I saw AYY & bDM displaying (SF-2) for an unbG 10 minutes later. Today was the first real day of the rainy season. Rain cut short my radiotelemetry at first beach - BOY is still in approximately the same place. I made a rain gauge from an empty capillary tube case, & collected 2mm of rain from 18:30 - 21:00.

DuVal E.H. 2000 Journal Isla Boca Brava Chiriqui Prov, Panama 25 Apr ena My present concerns about the research are: our measurements do not seem to be consistent enough between days + observers to be truly reliable. It's a little late to worry about this 234 birds into the project, but I'm worrying anyway. "Skull-to- tip" seems particularly unrepeatable, but even important standards like tarsus are often more than a little off. I guess I need to pull out one of the specimens + have us re-train. April 2000 weather: sunny & clear, cloudy in afternoon, but no rain. Still & hot at night.

DuVal, E.H. 2000 Journal Isla Boca Brava, Chiriqui Prov., Panama 9 April 2008 Weather: Sunny, hot, partly cloudy, rained very briefly at Bridge in the am (not at the restaurant) I stayed back to oversee the repairs Francis workers were making to the cabins, and Mark & Pat opened the nets at Bridge. It seems that catching RIBB put an end to activity at the lab for at least a day. We caught a slow trickle of birds - 9 for the entire day. During the mid-day break I went to check/stake out nest E-2. After an hour of watching for the female, I looked into the nest and found both babies dead, with ants beginning to eat them. It wasn't clear whether they'd been killed by ants, or starved to death, but the bodies were nearly intact and showed no sign of trauma. I collected them and stored them in ethanol after removing heart & liver tissue & freezing those in EtOH. Bycatch included a green

Today we did observations at Bridge 2nd Beach (2) CC (4) EDM (1) 2nd landing (1) Well (1) First Beach (2), 2nd Beach (1). Kat did telemetry work but the batteries were running low (~45 mints) and I didn't track in the afternoon. The DMs at 2nd Beach (2) are all banded, thank goodness, but were doing nothing but down-whistling at me. Kat found a nest of blackheaded antsnakes being attacked by ants. The chicks were writhing and alive when she saw them; two hours later they were dead and entirely coated in black ants. So it's not a wild theory that

More importantly: I saw a new species (for me) of snake crossing the snake field path as I went to 2nd B2a at 10:15. Black back w/ yellow speckles dorsally on anterior 1/2. He left very rapidly. Isla Boca Brava, Chiriqui Prov., Panama E-2's chichos were killed by ants. Kut and I both staked out K-15, and she got a White-over-Al, & I got an Azul (maybe). Pretty disappointing return on hours of waiting. Yesterday Mark got up first. Today he ate all of our extra food in anticipation of tomorrow's trip to David. Kut got the Steinbok glass. Some [illegible] beach-goers seem to have made off with our door (lunch site). 1 May 00 weather - overcast all day, rain for ~35 min starting at 4:30pm. I'm reading The Beak of the Finch by Jonathan Weiner today & it's making me consider some - things that I had not about manaking: If selection can be divided into life-stage forces, pushing + pulling different types of birds in different directions, then it's perfectly feasible to study evolution in this impossibly long-lived species. As far as social selection goes, males of different plumage classes,

Duval, E.H. 2000 Journal Isla Boca Brava, Chiriqui Prov., Panama May can't are the obvious divisions. But I would have to be omniscient to know which birds ever displayed & with whom... hmm. Something to think about. Today we set two nets to try to catch BOY and remove her radio-transmitter, but failed. We did catch three other banded females, and attached transmitters # 071 (freq. 151.071) to RBV, # 010. I found her with the attenuator on high two hours later, just south of first beach (1), (but I didn't actually see her). Kat did a nestwatch at K-15 and reported WBA as the female; there is no WBA, but WBV was banded very close to there recently... I don't like deciding these females by inference! I'll try to do another nest watch there before the nestlings fledge. Kat managed watched at two parches, but with the morning eaten up by BOY, Mark and I only managed one each. Mine was at EDM (2), where the male insisted on

There seems to be one male who doesn't interact much with the EDM regulars, but I'm having a hard time watching him. I stalked out K-4 and saw WVR, who Kat thought could be the mother. However, we caught her today & her bp was only 1: certainly not at a level you'd expect for a bird with 5-7 day old nestlings! Due to the recent rash of nest failures, I bled K-4 today for insurance. May 2000 We took the day to go to David with Frank and I managed to dispatch the liquid nitrogen problem immediately - I filled the tank without problems and sent it on errands with Frank. When I made it home, he met me with a story about the lid flying off en route and it took a while to understand that he did have the lid, still... Whew. The day went amazingly, amazingly well.

DuVal, E.H. 2000 Journal Isla Boca Brava, Chiriqui Prov., Panama May 2008 Today was the day off for this week, so I didn't start work until 1:30pm. But I opened unsuccessful nets for BOY and closed them because it was too windy; radiotracked ABY and RBV, and banded M-6 and K-15 to completion. NWN ('the littlest All Black') in K-15 is 4g lighter than his brother NOV. He has sores on his head from insect bites and just generally looks like he won't fledge any time soon. NOV, on the other hand, is strong and well-feathered, and made a short flight away from me. M-6 similarly has a runt, but he's the runt by less than 2g. So it seems that manakins hatch asynchronously, barely. Interesting. M-1 had one baby stay in the nest for about a day longer than the other, but we didn't actually check to see that it was the littlest sibling.

DuVal, E.H. 2000 Journal Isla Boca Brava, Chiriqui Prov., Panama May 2000 Weather: Overcast, mostly still w/ mid-day breeze, ~90 F; no rain. There's so much to do. I don't have an organized system for rotating watches through our perch sites, and I can tell that will be a major fault of the project unless I work it out. The problem is that a rotation requires knowing what I want to get from the data, & I want everything. I need to know the dominance rank of all males, who copulates w/ whom, etc, and we're still having trouble reading band combinations. I know I'll need to take a subset of sites to keep things realistic, but... which? And what good is it to only know dominance in ~10 pairs of males? And while I fret over that, the unfound nests are fledging, BOY's transmitter is going to waste, and we still don't have mama ID's for some-to-fledge nests. Kat and I netted unsuccessfully for BOY until 1000, while Mark did telemetry. We each did 2 behavioral

DeVal, E.H. 2000 Journal Isla Boca Brava, Chiriqui Prov., Panama observations, & I stalked K-4 while Mark stalked M-9. I banded K-4's babies both NA_al (NAP x NAB) and M-9's NWPal and NPXWal (the littlest one still needs 2 bands). I got complete blood samples on both nests, and a parasite swear from NPW. I found 2 new nests; one under construction near 1st Beed, & one probably already failed near M-9. A huge proportion of nests seem to fail before or soon after hatching. So far 14 babies have survived to be bled, & we have mom ID's on 10 of those. 5 May 2000 Weather: Slight breeze mostly overcast, hot. Mark and I set nets for BOY but didn't catch her again. I think that was our last chance to target-net, since her baby is very close to fledging. I stood on a chair to take him out of the nest with Mark steadying the base. He flew out of my hand as I took him from the nest, & I caught him in mid-air. He is now [illegible] # 255. NPY

Journal Isla Boca Brava, Chiriqui Prov., Panama 5 May cont. We also caught RBV, who had spiderwebs wrapped around the antenna of her transmitter but otherwise seemed to be handling it very well. No visible imitation of skin/feathers. I guess the spiderwebs explains the white stuff on BOY's antenna when she swooped past us yesterday. M and I did two watches each (2nd Beach (1), BT (1), CC (4) + EDM (1)) and Kat did the radio tracking & nest-searched for the rest of the day. One nestling (the smallest) May 2000 Overcast & still all day, storm of rain in the afternoon. Kat and I did 3 watches each while Mark did telemetry & nest-searching. RBV (transmitter 1071) is the mother of two nestlings in K-16 (a nest we'd already found). Perhaps it's bad luck, perhaps it's a good sign that we're finding the majority of the nests. Mark stated M-9 and

DuVal, E.H. 2000 Journal Isla Boca Brava, Chiriqui' Prov., Panama' 6 May cont. got the mom's combo - # AOG. Yikes! Two more genetics data points, though one of the babies is dead. Mark caught AOG eating the chick's fecal sacs; the fourth time he's seen such a thing during nest-watches. The female feeds the babies first, then picks off a sac & simply swallows it. The babies do regurgitate fruit seeds that are too large to be digested, just like the adults. I've found them in the nest with a fresh, cleaned pit resting by their bill - #4 was littered with two kinds of pits. I collected samples of both & stored them in a manilla envelope on 5/5/00. The clinging seeds often (~50% of 8 seeds) housed large, white guts that had eaten away the inside. May 2000 Clear & sunny, 87° in the morning. 13mm of rain in the afternoon. The telemetry equipment continues to cause problems. I couldn't get a signal from any of the birds all morning, except for a few faint beeps from BOY & RBV when I was up near the cleared lots: they're

I was looking for ABY specifically, x so continued on to walk the "Adventure Trail" through the former horse pasture with no success. Afternoon I was again unable to raise a signal for any of the birds. I left the receiver & antenna near Acacia while I went net-searching (found E-I x E-J). When I got back, there was again no noise at all from the receiver (no static, same problem as yesterday). I took the equipment back to keep it from being rained on. There is a faint static noise that can only be heard if the volume is all the way up and your ear is pressed to the machine. Mark & Kat did watches in the morning, and we all nest-searched without luck in the afternoon, after the downpour. It's really the rainy season now!

I could definitely make a study of gecko behavior here, though I think add fascination with reptiles in the bar might not go over as well as my usual fieldwork. There are certainly different species and a lot of dominance interactions. How could I find out what species of gecko are in Panama? The 7 lightposts in the restaurant (were in the path to el baño) make wonderful discrete territories. Perhaps I should look into the gecko literature & think it over for a side project next year? We discussed the rotation of observations today, & the consensus is that it would be best to watch about 10 DP's intensely, and just try to lagartijo <-lagartijo=gecko figure out who's who at the other. But: 10 DP's, or 10 leha? I guess 10 lehs wouldn't really be possible. I want to have a large enough sample size to be

DuVal, E.H. 2000 Journal Isla Boca Brava, Chirigui Prov., Panama able to get significant results... How about: 3 leks; watch all DP's regularly could answer: How much exchange between DP's is there? Is the same ♂ dominant at all the perches? Do ♂s visit the or just the 1° one? Need simultaneous watches! 10 DP's watched intensively; select 1 per lek w/ lots of activity could answer: Who is α/β? All dominance ranks T levels different between α/β? Behavioral descriptions Perhaps know den status of ♂ w/ paternity Song rate different by T, rank? Type of partners different? Are partners relatives? Additional perches: ♂'s known to display? Perhaps rank? (for paternity question) partners who attract females for display. So what are the leks?

DuVal, E.H. 2000 Journal Isla Boca Brava, Chiriqui Prov., Panama' 8 May 2000 Weather: rain at night - just a little. Partly cloudy in the afternoon/morning. 3 observations each today, and the telemetry equipment magically began working in the afternoon. I tracked BOY & ABV but still Got no signal from ABV. Her transmitter has (should have) more battery power than BOY's ... Kat found a nest near first beach with two chicks (I knew there had to be more chicks somewhere!). I found two nests under construction: one near 2nd Beach (3) and one in between 2nd Beach (2) and Main Street. The latter was revealed to me when I noticed a female landing near R-4 (a recently failed nest) while I was doing a watch at CC (1). when I saw her a 2nd time I went closer and watched her circle the nest, land on it and peer in, then grab fiber from the nest and hover upwards pulling it. She blew off across the bamboo path, & I stationed myself farther and farther along her route until I found her nest. ;

DuVal, E.H. 2000 Journal Isla Boca Brava, Chirigui Prov., Panama' 9 May 2000 Weather: Partly cloudy all day, rain beginning ~5:30 and continuing sporadically. Today was the "day off" so I slept in and went out at 7:30 to target net at Central Clearing (5) for the unbanded DM. I saw two unb DM's QR'ing together shortly before I captured one at 11:45, so I guess there's always more work to be done. I also caught 2 unb G's, RRE, PYP & YPY, & the female from former E-1 nest (though I need to check that one). Clint passed his orals today! It took some elaborate planning to get to Boca Chica to find this out but it was worth the trip. I banded the first bird of the day "OR/Aal" as Clint was probably waking up. I continued netting with less success in the afternoon, & finished The Beak of the Finch. I didn't find time for telemetry work today.

Are we catching them before they have a chance to lay, have they already been depredated, or did they grow and fledge without us? I suspect the middle option. We netted at Well today, again, and caught another 2 unBDM's (plus 2 previously banded.) I was getting snappish simply because I'm worried about not being able to get everything done before the end

Unfortunately, I still think it would be possible to meet that goal in DM's alone.

DuVal, E.H. 2000 Journal Isla Boca Brava, Chiriqui Prov., Panama 13 May 2000 Weather: 47mm of rain, starting at ~4:00. We did 3 observations each, & Kat saw a possible capulation at the new site "Triple Creek Junction." (male banded). Mark got band combes for M-11 (YRR, formerly listed as male due to her quite large red cap). It was a day of snakes: Mark saw a green "vine snake" that sounds like the one I saw last year - dark eye stripe, brighted lighter green head, darker green body. It was about 2m long & ~1" in diameter. I found a very large possible boa, that could be the same thing that Frank ID'd as a Boa de lance in our first few weeks here. I spotted him moving downhill from 2nd Beach (2), where he was being mobbed by ants & snakes. Note: We haven't seen a Swainson's tursh in weeks now.

Journal Isla Boca Brava, Chiriqui Prov., Panama 18 May Rain all day. 29 mm We slept in and did paperwork until lunchtime, summarizing our nest data on "spreadsheets," plotting nests onto the island maps, and beginning to summarize the behavioral state of affairs at Bridge (Mark). I read through the buildup of behavioral observations and filed them in the appropriate places. Mark went nest-searching and then we all attempted to do the vegetation estimates at nest M-1. We only managed 3 of 9 required 2m2 plots before calling it a day -- vegetation work is phenomenally frustrating! I stayed out K-23 for 40 min & saw WA again, but the light was too poor to read her third band. One baby disappeared yesterday, but the younger one is still in the nest. He still has a visible sore among the pin of one wing from insect bites. I think Frank is getting tired of my frugality. I think I'm getting tired of sniping comments about my stinginess as an employee.

Behavior watches were interrupted by the afternoon rains and the fact that the coffee maker(s) (hotpot and dragonfly stove) were broken. We had a cup of coffee in the restaurante before returning to continue veg work on M-1. The world was a much happier place after a little caffeine. While in the restaurante we met Lionel, the head of ANAM for Chiriqui. He wants us to survey the birds on Isla Parida, where the marine park ranger station is located. This would give us a chance to catch manakins in a new place for the metapopulation segment of the study, as well as being something of a working vacation. Lionel was a bit tipsy, but Frank says his offer is genuine and he'll take us there, feed & house us, and bring us back. Frank also suggested that Lionel could grease the wheels of permits for work in Chiriqui. During my first watch, at First Beach (F), I heard a

I still feel like she has to have her nest near DFG. I did veg on K-16 & Mark did M-14. I'm not sure which nest Kat did, but it takes approx. 2 hours to do a complete veg sampling on a nest. Everything just sucks time away from the behavioral observations! I target- netted for the unbDM at BTE in the afternoon with no luck (though I cought 4 previously banded birds).

I think she would have chicks by now... I intended to track her at night, but this night has dragged horrendously. Packing has taken a while, since all the research equipment had to be put away.

Don Luis says that a man named John Zook, who is a Costa Rican ornithologist, went to Las Alturas (in a lower area than the station where I stayed last year) and noted that the lance-tailed manakin behavior seemed strange. He wasn't sure which species to classify them as. I meant to get Zook's email but forgot to ask for it before leaving. I'll have to email Luis. In La Amistad I saw two DM's 'que-rico' together, and found a more dense (a ranger) population near the coffee field of Rafael, up the road a ways from Las Tablas ranger station. The vocalizations seemed identical to those here, though they didn't seem to be doing much QRily and I heard no dancing. We also saw 3-wattled bellbirds, a chestnut-mandibled toucan, and a flock of crested guans. The station is lovely, if a bit tense & gun-heavy due to conflicts with poachers in the park. It seems like it would be a nice place to work. Ask at the MINAE office in San Vito for info on use of the ranger's house.

No vocalizations. GRG was acting "nesty" in the same area (first beach) last week; perhaps the G bird is her chick? The DM's started dancing and I never got the chance to confirm that the G was unbanded. 29 May 2000 Rain after 5:00 5mm Sunny early Behavioral watches (8) and one nest vg (K-24).

I repaired the Avinet 9m net, Mark did a vag count on E-13 (and got some odd looks from Danielle while he was using the bright pink measuring tape), and Kat stalked M-14 (mon = -PV probably). We caught a total of 20 manakins (the 1 white-tipped dove b.gcatch escaped from the net), and only 3 of them were new. Of those (all greemies) one had extremely worn feathers and another was clearly young-of-the-year (all feathers new, body totally in p.i.x., bright gape). Interestingly, the "juvenile" still had a skull of 6. We have caught one bird with skull windows... The unbanded DMs that we were aiming for evaded the net quite successfully.

I guess I'll be spending my lund hours there for a little longer. We captured WBW, whose number does not match the number for her in the Master Banding List. It is possible that we've double-banded yet again (we didn't check the MBL until after the bird had been released). WBW has joined VVB (who we still have no blood from) on the hit list of most wanted birds. I staked out K-25 to no avail. As with K-23, the female returned and sat on a low perch near the nest for several minutes, slowly surveying the surroundings. At this point, a tourist walked by and the female left. At K-23, the female then flew to the nest to feed the babies, & ate the fecal sacs. A key capture today was ABY 090, who was carrying radiotransmitter

She was in much better condition than RBV; she still had a trace of fat, weighed over 20g, had no bare spot worn on her back, and only one slight sore, mostly healed, under one leg. Not bad. I could continue telemetry work if they all held up as well. Now BOY was the only transmitter still out there (with dead batteries). I'd like to 'redeploy' 151.071, but the receiver has been dead since the Costa Rica adventure. ABY's battery was very slightly rusty. We caught 2 birds (in the last 2 days?) who appeared to be young-of-the-year.

The way you looked at me with those big green eyes made my heart race every time I saw you. You were so full of life and energy, always smiling, always laughing. I think about you often now, even though we haven't spoken in years. Sometimes I wonder if things would have been different if we had stayed friends instead of drifting apart. You taught me so much about love and friendship during those days together. Your kindness and generosity left an indelible mark on my soul. Even after all this time, I still miss you dearly. Hope one day our paths will cross again. Yours truly, [signature]

Within a minute, I heard dancing at (1). I followed it to the dp & saw a distinct TC of the same description on the dp. Again, she left.

It seems to be common wisdom that motmots consciously pluck out the feather sides to form their racket tail. This intrigues me because it seems so unlikely. Far more likely would be a genetic (inherited) tendency for these barbs to weaken & thus break off more easily as the feathers age. I guess that testing this would require pulling out the tailfeathers of captive motmots & watching them regrow several times. Perhaps with 200 animals? What zoo has a large population of motmots? Mantarin activity at the display perches is definitely flagging. I hardly heard any QRing while I netted today, & our last many watches have been mostly blank or just long fallies of aw, to, & walk calls.

Then again, it's useful to document the decline in display perch activity, & the male associations still seem to be stable. We showed Frank the dancing video we have so far, & he was appropriately impressed. Yidkira had already observed it near Bee Trees, before the area was cleared. The video on tape 3 now includes some good footage of Mark singing his "Mayore Adventure" song (in honor of his nests located on the Frank-named "Mayore Adventure Trail") as he skips away down Main Street. It's amazing, given our luck, that Danielle, Javier, & Oldecimo didn't round the corner to see that. Centipedes abound, now that it's really the rainy season, and Frank thinks he saw a tinamou perched in a tree near the restaurant a few days ago. I have been hearing a haunting, quavery whistle that rises in pitch & is repeated ~5 times. It could be

My blood tites have been yielding the same pury amount of plasma no matter the amount of blood in the tube. I separated out the plasma as usual & then re-spun the two largest "red cells only" tubes & got a significant fraction of plasma again. Ugh. So I guess I need to be spinning harder. Mark did vee work on M-14, which recently failed; Kats afternoon watch stopped early for lack of activity; E - 19 failed (before we could bleed the babies or figure out the mother).

It seemed to be an accident. ;) We did 3 observations each today & Mark staked E-21 (still alive!) for 1/2 hour, to no avail. Kent says there's an unbanded DM at second landing. The morning was exceedingly quiet, though Kent managed to find manakin activity as well as observe copulations by rufous-tailed hummingbirds and the courtship flight of a little hermit.

I noticed that YP is the mother of E-21, and there are only 3 possibilities. YPG was caught with bpO while there were eggs in the nest and so can be ruled out. YPV has not been seen this year and is a possibility. But YPW is the final possibility, and mothered E-10 an appropriate amount of time ago to renest. E-21 is only about 10m from E-10... Interesting possibilities. How site-faithful are these females? I guess that W4G moved considerably to renest... but then, her first nest failed and E-10 fledged. I can't wait to see the genetics!

I spent the morning waiting for an appropriate time to call Lionel from ANAM (personal # = 775-2055), but by the time I worked up the nerve at 8:30am there was no answer and I had wasted a big chunk of morning. Mark & Kat did 2 observations each in the morning, and I did one in the late morning at CC5. Afternoon watchies were cut short by the downpour. The tripod is broken and the video camera is now held steady by the magic of duct tape. We still don't have a good recording of DM's dancing together, or for a female.

He is now banded RPY. He was not caught badly - I only had to untangle the feathers of one really badly caught wing using Mark's technique of pulling the pomerica through the tight net to relieve tension (see opposite page). But after I finished taking blood I noticed that his right side was starting to inflate with the characteristic pepper-air sac symptoms: the skin was lifted well off the breast muscle, & the bubble was spreading. When released he was unable to fly (perhaps because his body was distended under that wing?). I placed him on a branch ~12m from the banding station. 40 min later he was perched a few feet away, barely off the ground. At 11:00 I was unable to find him. This is the 4th or 5th bird this year that has had this problem, and I'm still not sure what causes

Mark stahed his new nest today and found out that the female is unbanded. After an uneventful watch at bridge, I joined him to set up a single 6m net near the nest. We caught the probable mother of M-21 and banded her PYY. Mark took two vials of blood from each chick and collected a fecal sample. Kat had a fabulous first two watches, with observation of dancing for a juvenile greenio. Probable? In the afternoon I did a watch at 2nd B (2) and saw AWA SF-1 for an unbG juv - and video taped it! hurray! The broken tripod has made videoing much more challenging.

There was very, very little manakin action, though we saw many long-tailed (all unbanded) I heard one (relatively short) QR bout all day. Mark found a nest with 7-11 day-old chicks. We banded these (Bal x Gal) and target-netted their mother. The other nets caught only 3 manakins (all DM). One DM had a very scaly breast (almost brood- patch-like), and all had body feathers in pin. I wish we knew whether the TBB manakins were as quiet today... We didn't take the time to do much exploring unfortunately. Next year, it would be best to go there earlier in the breeding season, I suppose. -We also caught a white-tipped dove and green kingfisher. There's a vulture roost over the main path.

The third was a recaptured DM who was caught in the area when I target-netted E-13, but as of yet we haven't seen him display. Mark did an uneventful watch at BeeTree before meeting us with the ice, and we all did one watch after lunch. Well (2) was quite active, and I saw yet another bout of solo "baby dancing" as a vulp juvenile leaped about and gave warbly "eeek" calls from a high perch. I paid Frank this morning so that he could pay Amelia - she'll be in David for the rest of our time on the island. We had planned to take her and her daughter out to a movie during our one night in David, but Frank pointed out that she'll be returning with him that night. The sea slug biologists found a specimen on the shores of IBB that they haven't found in other parts of Panama (this is as far as they've come along the Pacific coast). Their presence prompted Frank to say that there are even worse jobs than watching little birds. :) Eek -10ml blood from E-22, RRR's chick.

They spent the pre-lunch hour precy [illegible] distances between dance perches. I stayed out in the rain and found a rufous-tailed hummingbird nest with two eggs at first beach.

We each did a farewell observation at the display perch of our choice. Kat chose Bridge 2, Mark chose 2nd Beach '/3 (population station'), and I ended up at CCS after some morning packing. I tried without success to leave the camcorder recording at the dance perch while I went to collect veg samples. I took Theresa + Jurnita's picture, as promised, and will mail them a copy via Frank. I tried my best to bleed the far-too-young chicks of E-26. I got a small drop of blood from the older one by pricking him directly in the thigh. The wing vein does not work for such young birds! I failed to get any blood from the younger sibling. The older baby had a 5 healing sore from mosquito bites. Packing took forever. Yadira found a baby boa on the back of one of the restaurant chairs, and Mark, Kat, and I passed him around, to the horror of the locals who believe they're venomous.

We went to EDM 1 and BRI 2 as a group and did a 2-hr. observation at each place. It reaffirmed the need to do two hour observations, as not much happens for long periods of time. We had a surprisingly hard time with reading bands - I guess I'd forgotten how difficult it really is. ARA was at bridge, and Eric saw RB-(DM) - perhaps RBB still is in power?

Then Eric got a DM (GRA, the mac-daddy, or one of them, from Acacia) whose leg he says was bent oddly in the net. When I took him out of the bird bag, I could tell it was broken. It seems like the upper leg joint was the culprit - the leg stuck out at a terrible angle and he wasn't using the foot.

But I really did feel like he deserved a fighting chance (museum specimens be damned). After all, he had clawed his way up to alpha or beta status - I can't bear the thought that our net destroyed his life, though it may have anyway. The draw- backs of not putting him down are that now I'm not sure he's out of the running at ACA - a "natural" halfway-removal experiment? Unfortunately, we didn't get bands on the ACA DM's in the two watches earlier in the week.

The dm was unband ed & did no Main St path (dp?) -new cross palm gully (dp1) co-display before mating. I saw the other at Bee Tree

Revised H3 1995 [illegible] I had a very good time at home last year. Soapy took me to school. I was able to pick up some guitar skills. I also got to hear about the war. It was hard for me when I first heard about it. But I tried to help out. 1065 Small St. I saw two girls in a park last week. They were talking to each other. We saw all of them together. For some time, they did not look like friends. The boys and girls were playing tag. [illegible] I certainly enjoy reading magazines about cars.

DuVal, EH 2001 caught a Kentucky Warbler - my mystery bird IDed at last, though the eyestripe seems to curve down behind the eye much more than in the field guide. Isla Boca Brava, Chiriqui Prov, Panama March 25th beach & I target netted at the new TZL perch, trying to catch the unb DM who was seen copulating there. No luck, but I did get a terrific female sample on APB (CB), & recaptured PYP(G), the ol' mama from last year's U-1. I'd love to find her nest again. 20 March 2001 We took the day to go in to David - LOTS of cuz!/ (4 hours?), plus some playing or dialpad.com, which lets you place free long distance phone calls to the US. The reception was awful, but I was able to communicate with Collins & Mom. I submitted an abstract to ABS for a poster on this project & asked Eileen for advice on teaching in the fall. Biff Bermingham wrote to say that he'd

CASCADA is entirely populated by unbanded birds, or at least during the hour that I watched. Katie did her afternoon watch at Well 4, & half the birds there were unbanded as well. Even with GRA out of action, there was a fair amt. of activity at ACACIA. Some fighting & fly-at displays went on between cerulean-backs.

Whimbrel on the beach as I walked back. 21 March ca[illegible]. 22 March 2001 We did the usual 3 watches each today, and things were surprisingly slow. Katie had a good watch at Bridge, but otherwise... I found (E-3) a nest at second landing that already has two eggs in it - same TREE as one of the nests last year. I think WBB (G) nested in the area last year, & during my watch WB- (G) was hanging around looking nervous. I nest-searched my way from WEL3 to SBE1 and came within a few feet of stepping on a quite large Boa constrictor. She started, I started, I backed up, & she advanced, so I turned & retreated quickly. A semi-chase! She never moved more than a few feet, but it certainly surprised me. 23 March 2001 Two tourists came out on my first watch today - Jamie & his father-in-law

DuVal, E. H. 2001 Journal Isla Boca Brava, Chiriqui Prov., Panama [23 Mar cat] Al. Al writes for a local Pennsylvania paper, and is doing a conglomerate story on Panama as he sees it while visiting his daughter & son-in- law, who are newly-minted peace corps volunteers. Jamie is quiet & interested. Al is loud, loud, loud, & doesn't entirely get the idea of what we're doing but asks a lot of questions. Even during watches. So my session at CCL1 was pretty much a wash - Al talked throughout, sat conspicuously, & never saw a mankin. Jamie came along on my second watch, too, and things were much better, noise-wise. Boxer continued his new tradition of sniffing us out in the morning and wrecking the watches with his rambling (often through the dance perch). We set 5 nets at TCJ for tomorrow.

Doval, E.H. 2001 Journal Isla Boca Brava, Chiriqui Prov., Panama 4 April 2001 There's been a long hiatus in field notes, but I'm going to do my best to fill in the gaps (or at least do better from now on). Yesterday was our day in David - $70+ on groceries, $26 for a high-class lunch, & I changed $350 in traveller's checks. Our stipend from STRI did NOT arrive, and letters sent to the APO address that I was told to use were returned to the senders. STRI sucks. (Just the thing to put in the MVZ archives) Eileen has not yet sent our thermometer. Today was the weekly "day off," so I went nest-searching & found a record (5w/eggs) 8 nests. Now is definitely the time to be out there. I netted for the unb DM at SPY in the afternoon, but just catched one unfortunate unb RC. The North wind was strong all day - not quite so bad as the one really windy day last year, but strong. A herald of the rainy season? Nest E-1 had no eggs, but there was 1 dented egg on the leaves below it. Perhaps a

Lou also told us that the plants here are typical 2° growth, but that there are also a few old-growth species remaining - I guess they were left in the initial clearing? 6 April 2001 The wind continued today, though it was still for our first watches this morning. Manakin activity seems very much disrupted by high wind. I saw a QRing DM blow off his perch this afternoon. I got banks in the E-ll area: YVG. I'm very relieved she's landed - it would be a pain to net in that gully. 7 April 2001 Finally the wind stopped this morning. I netted for the unBDM at SPV in the morning, just in case, but it stayed calm all day. The manakins began to display again, & we

The new idea for today is that I could present a fake f manakin to males on the display perch to incite dancing, hopefully, dominance-related behavior. If it works, I could use this to test the idea that beta males just act (less frequently) as dominant at subsidiary display perches. Finally, an experimental element to the work! If only the manakins will respond appropriately to a manakin manequin. Makes me wish I had Dave McDonald's paper on his plumage experiments here. Eric has already carved a styrofoam manakin for a first attempt. 8 April 2001 3 observations each today, as usual. The males at Acacia seem to have returned to their old places and are doing their usual long QR bouts, but it's GGR (DM) and a bCB now. I'm surprised that no DM has moved in.

DuVal, E.H. 2001 Journal Isla Boca Brava, Chiriqui Prov., Panama [8 Apr caiti] definitely moving between display perches, but it's hard to tell who is dominant at each location. (scratch that - that occured on Apr 7). We split up in the afternoon; Eric & Katie set nets at CCL for tomorrowt I ran nets (catching only a Swainson's Thrush) at Spin Palm leh. I had a bad watch at TCJ - one of my worst, rally - because the birds were active at 3 perches simultaneously but I couldn't find any reliable place to, sit & observe any of them. Same problem at EDM. 9 April 2001 - light rain, 12:30 - 1:45pm; overcast We had a wonderful day sitting at CCC, & caught 14 manakins. By-catch included the first white-winged Becard that we've caught (I think). We caught all of the known banded DMs in the area, but an unbDM is still eluding us. Katie did a nest watch at the E nest near SLN, & read WB - off the f's bands. Didn't a similar female have a nest in a similar place last year? M-11 or M-12? Eric has a nest w/ chicks now, too, but hasn't seen her legs.

Duval, E.H. 2001 Journal Isla Boca Brava, Chiriqui Prov., Panama 14 April 2001 Rain in the morning - light, for ~20min. We did watches as usual - 3 each. In both my 2nd (ACA) x 3rd (BR/2) there was a banded female enthusiastic constructing a nest behind the dance perch. PBG at ACA & w?yA? at BR! At Acacia, I saw (DM) GRA, who was injured on March 17 - nearly a month ago. He was chased by another DM (didn't see the bands), and was holding up his left leg - not continuously, but he would raise it after he landed. What a relief to know he's alive and trying to display again, if not succeeding. During a watch at Bridge, I saw a female manakin (AGW?) fluttering repeatedly at the vegetation. Typical nest-building behavior, but when I looked closer I saw that she was perching on a vertical sapling, right below a very new-looking vireo fledgling. She would flutter up to his level and apparently peck at him. She definitely appeared to be biting at his head & body, & he begged (or at least opened his mouth

I have no idea what her intentions were. Another Q (-Y-) was in the immediate area, though perhaps only because she was constructing a nest a few meters away. A third interesting observation was a flycatcher (yellowish belly, wide bill, white egestripe) stealing nest materials from an un- finished manakin nest just around the corner & up the hill at bridge. (E-N) We presently have 23 active nests, altogether: 4 have failed (may be inaccurate - Reader needs to update his nest section of the folder), + 22 that haven't yet had eggs. Many in that last category seem to have been abandoned before the ? even finished construction. Are our flags disturbing them? Hard to say. One of the R nests has a female who persists in sitting on it, even though it's still empty after a week.

Things should get better from now on, as the tourists taper off. E-9 appears to have hatched. The ? was sitting on the side of the nest in the normal feeding posture as Meghan & I walked by, & we left her alone.

He said he was going to call someone for us. John came down from Berkeley, and we spent the day there. We got a lot of good pictures. I think it was successful overall. 18 Apr I saw "the mob" at some point. They were just kids with a camera taking photos. I think they were trying to get close to the school. I didn't want to be photographed, so I hid behind a tree. It was funny because I thought I was safe, but then someone called me out. I felt like I needed to leave quickly.

DuVal, E.H. 2001 Journal Isla Boca Brava, Chiriqui Prov., Panama 20 April 2001 The North Wind started again at noon today. It seems like we may never have a rainy season this year. I target-netted the mother of nest E-9 and eventually resorted to despicable tactics. She was unbanded & totally unconcerned about being watched at the nest. I even set the net feet away while she sat still, watching. After she left & returned without hitting the net, I flushed her, bled the chicks, & caught her as she mobbed me. Traumatic for all involved, but the mission was accomplished. Katie & Eric each did 4 watches (3 2-hr. & 1 1-hr.). My 3rd watch, at CEL5, was so slow I stopped after 1 hour & went chick-banding. One of the chicks in E-8 was gone; fledged or eaten, with just one aluminum band. The other was still there, so I bled & banded her. E-7 was bled for the 2nd time & banded SA __d; needs a few more days for the tarsus to be long enough for the last band. R-1 chicks were poised to fledge, especially PSW, who was trying to fly out of my hands. WOW mobbed me as I handled them. That poor bird has been tormented more than necessary this year, but her chicks are fine. There's a new flycatcher (Olive-sided?) nest at BRIDGE by the new well; it's

The breeze continued throughout the night - cool & dry. 21 April 2001 The manakins were pretty much silent today as the North Wind continued, I'm less than I was last time worried about losing nest contents', since the majority of nests have chicks these days, & I'm well aware of how good those chicks are at hangi g to the bottoms of nests. I checked empty nest E-L today & found that it had two eggs! I had started to think that our empty nests always remain empty. Eric has one nest by SBE (the tractor area) that the female has been sitting on for more than two weeks - with no eggs. I wonder what she's waiting for?

Duval, E.H. 2001 Journal Isla Boca Brava, Chiriqui Prov, Panama 22 April 2001 Four nests with CHICKS failed today. An amazing streak of bad luck. One of the nests, R-2, definitely belonged to VVB - the one and only manakin whose blood is not on record. I went to set nets around the nest, and found her chicks dead & drying up. She came and flitted nearby, just long enough for me to confirm her bands. If she were simply abandoning the chicks, it seems odd that she would hang out and be worried after they were already dead. But then again, what else could have happened? I set a net, since she was in the area but didn't catch her. We had a good netting day, at least. Two more unbanded DMs were caught at Second Beach. 23 April 2001 We wrapped up netting at SBE, and we never did catch any of the key DMs for hormone samples.

1002 high 55 I was at the school and I saw a girl. She was very pretty and she had long hair. I liked her so much that I decided to ask her out. But when I got there, she was already with another boy. It broke my heart. I sat in my room and cried for hours. Then I went outside and saw a cat. The cat looked sad too. I felt sorry for it and gave it some food. After that, I felt better again. But then I remembered the girl. I thought about her all day long. That night, I wrote a letter to her. In the morning, I put the letter in her mailbox. The next day, I went to school early. I saw her walking toward me. She smiled at me and said "Hi!" We talked for a while and then she left. I was happy because she liked my note. But I didn't know if she would write back. I waited all day but no letter came. I felt disappointed again. Then I saw another girl who looked nice. I decided to talk to her instead. She laughed at something I said and seemed amused. That made me feel good about myself. So I stopped thinking about the first girl. By evening, I was ready for bed. But as soon as I lay down, I started missing her again. I told myself not to worry anymore. Still, every time I closed my eyes, I saw her face. Finally, I fell asleep. The next morning, I woke up early. I walked outside and saw the sun shining brightly. It reminded me of the girl's smile. I hoped she might come back soon. But until then, I had to live with my feelings. One day, maybe things will change. Until now, I keep hoping for a good old time again. The beginning grew out at second place.

Duval, E.H. 2001 Journal Isla Boca Brava, Chiriqui Prov., Panama 24 April 2001 Day off - Eric & I went to David for internet access, & Katie stayed here. SAA found time to set up the rain gauge - nearly halfway through the season, & it finally gets done! I've been slackin' off, it seems. No rain in a long time, though, so we haven't missed much. I emailed Kriste Cramer, an ex-Peace Corps gal who is interested in being a short-term field assistant. We'll see whether it happens or not. I think 3 people as assistants next year would be best. Eric & I walked along the Horacosta-Boca Chica road a ways in each direction before getting a lift from Reuben. Saw a flock of Eastern Kingbirds, a blue-black grassquit displaying, more Eupodius & board warblers along the way, right near the corral that's on the west side of the road near Boca Chica (15min walking?) & a house that's on the East side. It's a wooded gully that looks like decent manakin habitat. The Eupodius have appeared all at once, & the Swainsons Thrushes seem to have tapered off marginally.

DuVal, EH 2001 Journal Isla Boca Brava, Chiriqui Prov., Panama 25 Apr. 2001 We did watches as usual today. 2 nests had new chicks, but we've had a hard time getting bands on the females. Lots of nest-stalking where no female ever comes. I vagged 6 failed nests today, & we finally got the nest sheets in order. BY (DM) was @ SP4 with a horde of unb RCs. 3+ RCs QRing at once! At least a few were banded. Also a banded CB QRig with red cups there. Nest E-9 failed afterall. The chicks (10 d. old) were gone, & the striped band that I put on one of them to tell them apart was left sitting in the nest! I don't really know how THAT happened. 26 Apr. 2001 I target-netted two unbanded females with chicks in the nest, & Eric & Katie managed 4 full watches each to compensate. I found a nest in the same tree as RAG's nest last year. No eggs yet, but it bolsters the theory that the females are extreme site-faithful.

DoVal, E.H. 2001 Journal Isla Boca Brava, Chirgri Prov., Panama 4/27/01 Eric & Katie did 4 full watches each today while I netted for the two unbanded females who currently have nests with chicks. I caught the one at WEC3 (nest K-2) immediately i banded her YGW. The ? at E-16 (between ACA x BTR) was more difficult I caught BOB x ROY before the cubG was finally in the net (now GGW), & it took nearly two hours. Strong wind in the middle of the night for ~ 1 hour ; from the south for once! The birds are starting to dance again, at long last. Or, I should say, the females are shopping again. I found a nest in the gully across main st. & slightly East of FBE, in the same tree as RAG's nest last year. That inspired me to go searching for BOY's nest by FBE, & I saw a bird (GF) there but found no nest. Frank cut down E-21 (failed) & hung it in the restaurant as evidence of our work. Good thing we already did the veg survey! Mental note: don't move the blogs on the failed nests TOO close... I took blood from Paco to sex him genetically. Paco = Yablony orange-chinned parakeet chick the genetic gender ID is a present from me to Vicki.

DoVal, E.H. 2001 Journal Isla Boca Brava, Chiriqui Prov., Panama 28 April 2001 We netted at Bridge this morning and it was crazy as usual. We closed the nets just after 11:00 & had caught 18 manakins & a lot of interesting bycatch, including a blue-crowned motmot & a pair of red-legged honeycreepers that were so close in the net that they had their claws locked. We only caught one of the 3 TMs who seem to be displaying regularly there (YPB) - I hope we'll get ARA & BOW tomorrow. The afternoon was devoted to watches. We tried to fit in 2 2-hr. watches each to wake up for going to David on Monday instead of Tuesday. I dallied & found the yellow-+black snake down by the beach below our house. The alarm calls of 3t bird species (manakins incl.) gave him away. I took pictures on roll 2 (the first roll of slide film) and hopefully we can work out an ID from those. The peace corps volunteers from all of Chiriqui are at the restaurant for their quarterly meeting. Not the group that I expected them to be! We bought chacaras from Jae ---, who grew up in Indialantic -at least for a few years.

Duval, E.H. 2001 Journal Isla Boca Brava, Chiriqui Prov., Panama 29 April 2001 Today we continued netting at Bridge. I heard dancing as soon as we opened the nets at 07:10, & went to investigate. ARA (DM) and BOW (on) were doing cartwheels for an unbanded green ?, and were doing SF-2 with wing-clicks. The female was excited - hopping back & forth rapidly on the display perch. They danced for more than 5 minutes, and at the end of one cartwheel bout ARA gave an "EEK" (finally dominance affirmed!) ARA flew off to the west & as he was "swooping" full-speed back to the dance perch, he hit one of our nets. I took hormone samples within 10 minutes of capture, & they were chilled 18min 30 sec later (Eric ran for the ice). After we caught ARA, activity in the area pretty much ceased. Never caught BOW. We had 0.25 cm of rain in the afternoon. Tourist Gennie Viteri from Panama City ([email protected], 684-7189 cel.) invited us to do tourist things with her when we next go to town.

Hopefully that will turn around soon. 30 April 2001 We went to (& returned from!) David with frank today. $70 ish on groceries to try to stay Eric's starvation.

The K-2 and E-10 babies have odd sores all over their heads & bodies. Some of them have the festering look of tick bites, but I'm not sure what caused them. 2 May 2001 I continued to try to catch BOW - I'd really like to be able to write a solid paper on manaki hormones. No luck. There were manakins, & yellow-green vireos, and [white winged] [bearn] mobbing a medium-sized (25") boa (?) near SBE 1 when I did a watch there. I videoed him, as well as QR boots with AYY and RWR. Eric saw SF-1 for a female by an unband DM near but not at WEL 3. Rain in the evening.

There was another medium-sized snake being mobbed by manakins today. A boa?

It was being mobbed by manakin, yellow-green vioeos, & a white-winged becard. I recaptured 3 females, includ, th E-20 female, GBV.

Interestingly, he was perched in what was obviously a baby-roost: gelatinous, fruit-filled feces were under his branch, & from the quantity he had been there a few days. He left when I walked around for a better view, but was back in the same exact place when I returned in 15 minutes. ♀ AGW(G) & ♂ YWR (DM) were down-whistly aggressively at me and AGW was semi-wobbling, though the chick flew well out of my reach.

And no wonder we keep finding additional unbanded DMs around here. I tried to net Y4B one last time, & he eluded me yet again. This is a real problem for the hormonal study. But after four straight days of trying I was forced to give in and take down the nets. Hopefully we'll be able to sample at least 6 alpha-beta pairs by the time the season is through... Two of my empty nests had eggs today. We're well into the second wave of nesting, to be sure. I've found 36 active nests so far this year - and we've just passed the halfway mark! A record. There was a new insect phenomenon today. A large ant-like insect (they look like a cross between ants x mole crickets) has excavated holes all along main street & the adjoining path, overnight. Each hole is the same diameter (~1cm) and is surrounded by a ring of balls of earth. Some of the holes are plugged from within by more dirt. It looks like there's just one insect per hole.

DuVal, E.H. 2001 Journal Isla Boca Brava, Chiriqui Prov., Panama 11 May 2001 We each did four watches today (one a 1-hon one), and I still managed to confirm the ?'s bands at E-23 (BA_) and find three nests. None of the nests have eggs, but only one had seeds underneath it, so I have high hopes. Eric thinks a formal study of seeds found below nests, regressed against time the nest was active, won't work - there's just too much rot, seed predation, sprouting, rolling away, etc. than can affect the count. I still think it's worth a try - perhaps next year in the dry season? I counted seeds (in an ~1/2m^2 area) under R-2 yesterday and found 20 white 3-sided seeds (the most common under nests), one debly brown seed (2nd most common), & 10 shiny black Euphorbiacaea seeds that may have just fallen in the area. The majority of plants in that area are Euphorbiaceae. In the evening we met Bill Dawson, owner (?) of Crocodile Bay Lodge on Golfo Dulce.

Not much was accomplished. 16 May 2001 We took shifts netting at WEC 3 + 4 today - Katie did 2 watches in the morning, Eric did 2 at night. Eventually we caught a DM who MAY be the unb DM at WEC 4. We will see tomorrow. No rain.

Journal Isla Boca Brava, Chiriqui Prov., Panama 18 May 2001 Today Frank cleared Second Landing. Dance perch and all. He left our blue & striped flaga standing on their sticks, surrounded by nothing. It was such a beautiful spot, too. WVB's tree, where she nested for two years in a row, was cut down. Everything was, really. I need to see if we can get Frank to give me a little warning, so I can at least take b. before & after pictures. Luckily the birds don't seem to care so much. The same territorial males shifted over a few meters & were dancing for a female during Eric's watch. It's so depressing, though. The clearing goes all the way to the far rancho, as well. Big hunks of forest that I never explored, gone. We suddenly have four nests with chicks to stake. I got the females bands on one of them, but we've got an awful lot cut out for us.

Doval E.H. 2001 Journal Isla Boca Bravo, Chiriqui Prov., Panama [18 May cont] It rained last night and the birds were pretty active overall. I even saw action at TCJ 2, for once! 19 May 2001 He did watches as usual, + I finally saw some good evidence of dominance at CCL - copulation by WBR! Unfortunately I didn't see his partner's bands, though I'm nearly positive that it was ABA. They blew from CERig to the dance perch, + it seems unlikely that there was time to swap males, or the inclination to do it without a fight. Eric is sick. It started threatening rain at 3:30, + when I threw in the towel at 3:45, he was already asleep. The ? of E-28 is BW- & seems to be all green, which could make her BWP. The females of the other two nests with chicks still elude us.

DuVal, E. H. 2001 Journal Isla Boca Brava, Chiriqui Prov., Panama 21 May 2001 Last night the rain filled our rain gauge to overflowing. Katie and I netted at cascada this morning, with an attentive audience of construction workers - Claus's house is being built right by the leh. The third bird of the day was an unbanded TC ? whose left wing was injured in the net. She was unable to fold the primaries in properly, and unable to fly. So, after a little soul-searching, I euthanized her. My first attempt at thoracic compression. It works. Miserable day. She had an egg inside - more on the way - her ovaries were well-developed, 1 or 2 large eggs was more developed than the rest, in addition to the egg passing through her system. Eric found a nest with one chick out in Mangrove - as of yet no bands seen on the female for sure. Hopefully the chick will still be alive tomorrow and we can stab it. Eric is still sick, but wait - admit it. E-AQ unexpectedly has 4 new eggs in it. Huray! Still!

In the afternoon Katie & I took turns staking R-8, but on my watch the chick was gone & BPV was mobbing me with all her heart. Either the chick was just eaten, or had fledged in the last few hours & she was defending it. Got her bands, anyway, & Eric took blood from the chick yesterday.

Then ARA slow-flighted for a ? , & like ARA & BOW both danced for a female. Still no copulations seen at BRI. But ARA "eeked" 14 times (~every 30 seconds) during the dance. At the end, the ? took off- & so did BOW. Could they have just gone somewhere else? Maybe the female does choose between the males of a pair? ARA slow-flighted hopefully for another minute. Otherwise, the day was a slow one. Even SBEI was slow. 25 May 2001 I leave tomorrow for a nearly-week-long vacation, so I've been arranging & re-arranging the schedule for Eric, who will be holding down the fort for us. Today was a red-letter me because I checked nest E-31 and, through flushing the female & laterstaking the nest, & eventually figured out that the female was VVB, #37 : the only undated bird I don't have blood from, & the mom of the dead-in-the-nest R-2 chicks.

I hope it doesn't cause her to abandon THESE clucks, but it was a risk I was willing to take at this point. That means her E-9 from last year + R-2 from this year now enter the pool of real genetic data points. And... potentially three nests from the same female! A good test of partner fidelity, especially if we find her nest again next year. E-31 is only about 10 feet from R-2. Eric did a record 5 catches today (4 2-hours x 1 1-hour). Wow. I couldn't ake it.

ARW was just in the area, not necessarily displaying. GBN (CB) - may have been BGN(CB) - danced with a (DM) A_ in the forest just South of the crossroads to 2nd Beach. I didn't see the dancing, but saw both males leave the area. So chicks banded in the nest in 2000 will be CBs for the 2002 season. Good to know! So it's: end of 1st year - slightly BF end of 2nd yr - CB So third year = DM? Is this faster than the plumage phases for the long-taileds?

We hiked out to BTR and then did band-reading practice - bands hung in a sapling in known combos. Paula says it helped considerably, & recommended that I do that at the beginning & then regularly throughout the season with assistants. The training section of this in general could be a little more vigorous. We did watches in the afternoon. EHO at EDM x APA; PAW at BTR x BRI.

DuVal, E.H. 2001 Journal Isla Boca Brava, Chiriqui Prov., Panama 25 November 2001 Watchers today: PTW: SBE, EDM, ACA EHD: CCL, BTR, BRI There was a good amount of activity this morning - it seems that mandrels are more active early in the day during the rainy season. I saw WBR and AB(A) dancing for a female (on the dance perch) at CCL 1 (the old CCL 3, across the gully). AB- did the swoop display, but it wasn't clear that WBR had left the dp. I'm not sure that this is a dominance indicator, but it's interesting because alpha's have done the swoop in the past, & I remembered WBR as alpha at this site. Perhaps roles are reversed, or perhaps I had it wrong & ABA is the alpha? I started thinking seriously today about hiring a field crew manager. Maybe Katie? Frank says he will rent me two ranchos for $15 a night, together, if I want four people here this year. It could probably be worth it. Is it $450/mo - just like paying rent! Little hermits are still displaying in the CCL area. They started last June!

Daval, E.H. 2001 Journal Isla Boca Brava, Chiriqui Prov, Panama 26 November 2001 targeting the old ccc's the little hermit let area We netted at CCL1 all morning and caught two CB's - PGY and BRW. We also caught four hummingbirds: three rufus-tailed, one sapphire-throated. German tourists/guiders Karin and Horst Dillard (?) joined us to watch the whole production, and I let them each release a hummingbird. They were intelligent, interested folks who kept exclaiming to the other Germans (Clara, Mechthild, Frank) about how interesting these birds were. The local Germans looked less impressed, but then they've seen it all before. Paula and I did watches later in the afternoon - me at SBE1 and EDM, & Paula at BRI and CCL. AWP was QRing with someone who was not ARP at SBE3 - Perhaps ARP did die after being injured in a mistnet last June. AYY and RWR both seemed to have disappeared from SBE1. In fact, AWP was expanding his area toward SBE 1b. What if partnerships are so tight that a ?? loses the perch entirely if the ? is gone? Meghan sent a note - says she sent her few observations to me during an anthrax scare and didn't make copies. She may come & visit before we leave.

Journal I have written to you all about my birthday party, but I did not invite any friends. My mother and father were very sad when they heard that I was going to be 12. They said it would be a great day for me to celebrate with all of my friends. But I didn't want to go because I had too many things on my mind. I decided to stay home instead. My parents understood why I wanted to do this, so they let me have whatever I needed. I spent most of the day watching TV and playing video games. It was nice not having to deal with anyone else around me. When dinner time came, my mom made some pizza which we ate together. After eating, she asked if there was anything else I wanted to do before bed. I told her that no, just sleeping sounded good enough for tonight.

Duval, E.H. 2001 Journal Isla Boca Brava, Chiriqui Prov., Panama 27 November 2001 Paula and I set off early to open the net at CCL. We ran them from 7:30 - 11:30 and caught absolutely nothing. Meanwhile, I've been getting progressively sicker and am now suffering a full-blown headache. I talked with Celideth de Leon (formerly Mendoza) on the phone after lunch and she said that the permits are in order for netting at the Metropolitain Park and Rodman military base, with the exception that we are not allowed to work on the top of the hill or along the road leading to it - prime LTM territory, I'm told, but I'm sure we can work around it. Now I just have to talk with Alberto and ask him to pick up the permits. Perhaps he, Paula, and I can go out to dinner on Friday and plan the week's work? Only two more days left on Boca Brava, then. In the afternoon we did a watch each, after setting nets at SBE 3, 1, and near the crossroads. Perhaps tomorrow we'll have better luck... Paula thinks she saw ABA ech v WBR sit on the perch during a post- QR dance bout, but she wasn't sure vnb.DM QR w/ YVB (DM) at SLNI.

Duval, E.H. 2001 Journal Isla Boca Brava, Chiriqui Prov, Panama 30 November 2001 Important note: Yesterday Paula White saw a collared forest falcon at Acacia. It was perched & flushed in front of her to another perch. It matched the description (short broad wings, etc) in the book as well as the picture, & she had a fairly good look at it. She says it crashed fairly noisily through the undergrowth. It flew from the area where we sit for ACA watches north toward SPY, and stayed within 6' of the ground. This is the first sighting of one of those on the field site - a definite manakin predator. Manakins were in the area, as were many other birds. When the falcon went through, something alarm called and all birds in the area fell silent. Paula describes even a black-chested jay sitting very quietly in a palm, "peeking out." At least three manakins were in the area. Today we left Boca Brava at 8:00. Before we left, I saw an unBRc, ODM, & Blue-crowned MotMot in the tree by Amelia's house. The birds were QRing at EDM, but Paula discouraged me from pursuing them, & they stopped before I could work up my resolve. (& they

Alberto showed us an area near the canopy crane where he had seen displays in a previous year. Replaying two recordings of lance-tailed manakins (made by George Angehr and including pip, dw, +r, + walh) called in several birds that responded with dw's but stayed high in the trees. We drove back to the main office & checked (RC) the trail on which I saw dancing red-capped lance-tail last spring (2001), but we heard no LTMA sounds at all. <- to Albrook Main office guard house parking
