Antbird Guilds in the Lowland Caribbean Rainforest of Southeast Nicaragua1
The Condor 102:7X4-794 0 The Cooper Ornithological Society 2000 ANTBIRD GUILDS IN THE LOWLAND CARIBBEAN RAINFOREST OF SOUTHEAST NICARAGUA1 MARTIN L. CODY Department of OrganismicBiology, Ecology and Evolution, Universityof California, Los Angeles, CA 90095-1606, e-mail: [email protected] Abstract. Some 20 speciesof antbirdsoccur in lowland Caribbeanrainforest in southeast Nicaragua where they form five distinct guilds on the basis of habitat preferences,foraging ecology, and foraging behavior. Three guilds are habitat-based,in Edge, Forest, and Gaps within forest; two are behaviorally distinct, with species of army ant followers and those foraging within mixed-species flocks. The guilds each contain 3-6 antbird species. Within guilds, species are segregatedby body size differences between member species, and in several guilds are evenly spaced on a logarithmic scale of body mass. Among guilds, the factors by which adjacent body sizes differ vary between 1.25 and 1.75. Body size differ- ences may be related to differences in preferred prey sizes, but are influenced also by the density of the vegetation in which each speciescustomarily forages. Resumen.

Bird Ecology, Conservation, and Community Responses
BIRD ECOLOGY, CONSERVATION, AND COMMUNITY RESPONSES TO LOGGING IN THE NORTHERN PERUVIAN AMAZON by NICO SUZANNE DAUPHINÉ (Under the Direction of Robert J. Cooper) ABSTRACT Understanding the responses of wildlife communities to logging and other human impacts in tropical forests is critical to the conservation of global biodiversity. I examined understory forest bird community responses to different intensities of non-mechanized commercial logging in two areas of the northern Peruvian Amazon: white-sand forest in the Allpahuayo-Mishana Reserve, and humid tropical forest in the Cordillera de Colán. I quantified vegetation structure using a modified circular plot method. I sampled birds using mist nets at a total of 21 lowland forest stands, comparing birds in logged forests 1, 5, and 9 years postharvest with those in unlogged forests using a sample effort of 4439 net-hours. I assumed not all species were detected and used sampling data to generate estimates of bird species richness and local extinction and turnover probabilities. During the course of fieldwork, I also made a preliminary inventory of birds in the northwest Cordillera de Colán and incidental observations of new nest and distributional records as well as threats and conservation measures for birds in the region. In both study areas, canopy cover was significantly higher in unlogged forest stands compared to logged forest stands. In Allpahuayo-Mishana, estimated bird species richness was highest in unlogged forest and lowest in forest regenerating 1-2 years post-logging. An estimated 24-80% of bird species in unlogged forest were absent from logged forest stands between 1 and 10 years postharvest. -
FIELD GUIDES BIRDING TOURS: Amazonian Ecuador: Sacha
Field Guides Tour Report Amazonian Ecuador: Sacha Lodge III 2012 Jun 29, 2012 to Jul 8, 2012 Mitch Lysinger For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. Well, once again, Sacha Lodge proved that it just can't disappoint! What an awesome spot from which to base Ecuadorian, Amazon basin birding. Accommodations are delightful, the food delicious and abundant, the staff possibly as well-trained as at any other lodge (and so friendly), and the forests are just full of exciting bird species, from the understory all the way up to the canopy treetops! One of the most impressive features that Sacha has to offer - and certainly its greatest birding strength - are the jaw-dropping canopy towers; the metal towers and walkways have to be seen to be believed! How could anybody ever forget mornings spent up there, eye-to-eye with some of the hardest canopy species to find? Three hundred bird species can be a lot to digest in a week's worth of birding, especially when many of them are new to most folks! One thing is for sure though: it is always big fun! Picking favorites is a personal thing, but there are always some birds - whether for rarity's sake, or just because they are flashy or performed well - that deserve some special recognition from the leader. So here are my picks for their moment in the birding limelight: how about that Bartlett's Tinamou that came strutting out right in the open for us... and that happened to be a visual lifer for the leader!?; that immature Agami Heron that even -
Birding the Madeira‐Tapajos Interfluvium 2017
Field Guides Tour Report GREAT RIVERS OF THE AMAZON II: BIRDING THE MADEIRA‐TAPAJOS INTERFLUVIUM 2017 Aug 1, 2017 to Aug 16, 2017 Bret Whitney, Tom Johnson, and Micah Riegner For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. Incredible sunsets were met with full checklists, full (and then empty) caipirinhas, and full stomachs back on our riverboat home, the Tumbira. Photo by guide Tom Johnson. An extended voyage into remote areas full of amazing birds but infrequently visited by birders? Yes, please! This two-week tour of the Madeira-Tapajos interfluvium (south of the Amazon) was chock-full of birds and lots of adventure in a comfortable setting with fantastic company. We kicked off this grand adventure in Amazonia in the bustling metropolis of Manaus where we boarded a comfortable and fast speed launch, checking out the meeting of the blackwater Rio Negro and the whitewater Solimoes just downstream from Manaus before blasting off. We shot down the Amazona and then up the Rio Madeira to the riverside town of Borba, cruising past Amazon River Dolphins, Horned Screamers, and Short-tailed Parrots along the way. Borba was our home for three nights, and we used this frontier base as our hub of land-based exploration of the right bank of the Madeira. This was a location notable for the ornithological collections of Natterer, and an area that Bret has visited repeatedly due to its interesting avifauna. Contrasting with a fire-choked season during the tour in 2015, we were fortunate to bird several excellent forest tracts this without issue - well, our endless stream of replacement VW Combi vans notwithstanding! Fortunately, our team on the ground managed our vehicle problems and we were able to continue birding. -
TOUR REPORT Southwestern Amazonia 2017 Final
For the first time on a Birdquest tour, the Holy Grail from the Brazilian Amazon, Rondonia Bushbird – male (Eduardo Patrial) BRAZIL’S SOUTHWESTERN AMAZONIA 7 / 11 - 24 JUNE 2017 LEADER: EDUARDO PATRIAL What an impressive and rewarding tour it was this inaugural Brazil’s Southwestern Amazonia. Sixteen days of fine Amazonian birding, exploring some of the most fascinating forests and campina habitats in three different Brazilian states: Rondonia, Amazonas and Acre. We recorded over five hundred species (536) with the exquisite taste of specialties from the Rondonia and Inambari endemism centres, respectively east bank and west bank of Rio Madeira. At least eight Birdquest lifer birds were acquired on this tour: the rare Rondonia Bushbird; Brazilian endemics White-breasted Antbird, Manicore Warbling Antbird, Aripuana Antwren and Chico’s Tyrannulet; also Buff-cheeked Tody-Flycatcher, Acre Tody-Tyrant and the amazing Rufous Twistwing. Our itinerary definitely put together one of the finest selections of Amazonian avifauna, though for a next trip there are probably few adjustments to be done. The pre-tour extension campsite brings you to very basic camping conditions, with company of some mosquitoes and relentless heat, but certainly a remarkable site for birding, the Igarapé São João really provided an amazing experience. All other sites 1 BirdQuest Tour Report: Brazil’s Southwestern Amazonia 2017 www.birdquest-tours.com visited on main tour provided considerably easy and very good birding. From the rich east part of Rondonia, the fascinating savannas and endless forests around Humaitá in Amazonas, and finally the impressive bamboo forest at Rio Branco in Acre, this tour focused the endemics from both sides of the medium Rio Madeira. -

Brookings, South Dakota, U.S.A. II Universidade Federal do Paraná. Palotina, Paraná, Brasil III James Cook University. Townsville, Queensland, Austrália IVLancaster University. Lancaster, Lancashire, Inglaterra Abstract: This paper describes the avifauna sampled at the São Luiz farm, in Northern Mato Grosso State, a Southern Brazilian Amazonian forest site. The avifauna was sampled at forested and open sites, between 29 June and 27 July 2008, using point counts, mist-nets and general observations. We recorded 194 bird species within 18 orders and 46 families. The records of this study expanded the known range limits of at least 16 bird species. Despite the need for sampling in other seasons, the rarefaction curves indicate a representative sampling effort. The bird community observed at this site contains most of the species typically associated with Amazonian forests, south of the Amazon, and suggests that ‘transitional forests’ found at this site should be qualified as ‘Amazonian’ when considering their legal status. Our data highlights the importance of this anthropogenically-impacted and poorly-known region of Amazonia. Keywords: Bird checklist. Amazonian Birds. Northern Mato Grosso. Southern Amazon. Resumo: Este estudo descreve a avifauna amostrada na fazenda São Luiz, norte do estado do Mato Grosso, uma área de floresta localizada no sul da Amazônia brasileira. -

Colombia 1 000 Birds Mega Tour II 21St November to 19Th December 2014 (29 Days)
Colombia 1 000 Birds Mega Tour II 21st November to 19th December 2014 (29 days) Lance-tailed Manakin by Dennis Braddy Trip report compiled by Tour Leader: Rob Williams Trip Report - RBT Colombia Mega II 2014 2 An early start on day 1 saw us heading to Mundo Nuevo. Our first stop en route produced a flurry of birds including Northern Mountain Cacique, Golden-fronted Whitestart, Barred Becard, Mountain Elaenia and a Green-tailed Trainbearer feeding young at a nest. We continued up to the altitude where the endemic Flame-winged Parakeets breed and breakfasted while we awaited them. We were rewarded with great scope looks at this threatened species. The area also gave us a flurry of other birds including Scarlet-bellied Mountain Tanager, Rufous-breasted Chat- Tyrant, Pearled Treerunner and Smoke-coloured Pewee. We continued up to the edge of the paramo and birded a track inside Chingaza National Park. Activity was low but we persisted and were rewarded with a scattering of birds including Glossy, Masked and Bluish Flowerpiercers, Slaty Brush Finch, Glowing and Coppery-bellied Pufflegs, and Brown-backed Chat-Tyrant. The endemic Bronze-tailed Thornbill only gave frustrating brief flyby views. Great looks however were had of the endemic Pale-bellied Tapaculo, singing from surprisingly high up in a bush. The track back down gave us Rufous Wren, Superciliated and Black-capped Hemispingus and Tourmaline Sunangel. Further down the road a Buff- breasted Mountain Tanager and some Beryl-spangled Tanagers were found before we headed back to La Calera. After lunch in a local restaurant we headed to the Siecha gravel pits. -
Brazil's Eastern Amazonia
The loud and impressive White Bellbird, one of the many highlights on the Brazil’s Eastern Amazonia 2017 tour (Eduardo Patrial) BRAZIL’S EASTERN AMAZONIA 8/16 – 26 AUGUST 2017 LEADER: EDUARDO PATRIAL This second edition of Brazil’s Eastern Amazonia was absolutely a phenomenal trip with over five hundred species recorded (514). Some adjustments happily facilitated the logistics (internal flights) a bit and we also could explore some areas around Belem this time, providing some extra good birds to our list. Our time at Amazonia National Park was good and we managed to get most of the important targets, despite the quite low bird activity noticed along the trails when we were there. Carajas National Forest on the other hand was very busy and produced an overwhelming cast of fine birds (and a Giant Armadillo!). Caxias in the end came again as good as it gets, and this time with the novelty of visiting a new site, Campo Maior, a place that reminds the lowlands from Pantanal. On this amazing tour we had the chance to enjoy the special avifauna from two important interfluvium in the Brazilian Amazon, the Madeira – Tapajos and Xingu – Tocantins; and also the specialties from a poorly covered corner in the Northeast region at Maranhão and Piauí states. Check out below the highlights from this successful adventure: Horned Screamer, Masked Duck, Chestnut- headed and Buff-browed Chachalacas, White-crested Guan, Bare-faced Curassow, King Vulture, Black-and- white and Ornate Hawk-Eagles, White and White-browed Hawks, Rufous-sided and Russet-crowned Crakes, Dark-winged Trumpeter (ssp.
