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. -

The Influence of Agriculture on Avian Communities Near Villavicencio
GENERAL NOTES 381 By day 35 foot span already averaged 99% of adult size. Rapid attainment of adult foot size likely reflects the importance of the many tasks the foot performs (e.g., perching, climb- ing, feeding). At hatching, bill width was already 49.4% of adult size, although, at day 35, bill width was closer to adult size than length or depth. This was the result of a more rapid development in width before hatching, since the growth rates of all bill dimensions were about the same throughout nestling development. Since bill width was measured at the base of the bill, it is about equivalent to gape width. The rapid increase of gape width in other species (Dunn, Condor 77:431-438, 1975; Holcomb, Nebraska Bird Rev. 36:2232, 1968; Holcomb and Twiest, Ohio J. Sci. 68:277-284, 1968; Royama, Ibis 108:313347, 1966) has been interpreted (OConnor,’ Ibis 119:147-166, 1975) as important in increasing parental feeding efficiency because it allows the young to consume larger food items. Young Monk Parakeets are fed by regurgitation. This material was described as a white, milky fluid (Alexandra 1977). Ac- cordingly, the ability to consume large food items may be of little value to nestlings. Since food is provided by the parents in a rather processed form, there would be little advantage in rapid bill growth for the purpose of processing food items. Fledglings, too, are fed by regurgitation, although they soon begin to do some foraging for themselves. Yet, as Portmann (Proc. 11th Int. Omithol. Congr. 138-151, 1955) has shown, as the brain develops early, the skull must develop similarly to accommodate it. -

Ecology, Morphology, and Behavior in the New World Wood Warblers
Ecology, Morphology, and Behavior in the New World Wood Warblers A dissertation presented to the faculty of the College of Arts and Sciences of Ohio University In partial fulfillment of the requirements for the degree Doctor of Philosophy Brandan L. Gray August 2019 © 2019 Brandan L. Gray. All Rights Reserved. 2 This dissertation titled Ecology, Morphology, and Behavior in the New World Wood Warblers by BRANDAN L. GRAY has been approved for the Department of Biological Sciences and the College of Arts and Sciences by Donald B. Miles Professor of Biological Sciences Florenz Plassmann Dean, College of Arts and Sciences 3 ABSTRACT GRAY, BRANDAN L., Ph.D., August 2019, Biological Sciences Ecology, Morphology, and Behavior in the New World Wood Warblers Director of Dissertation: Donald B. Miles In a rapidly changing world, species are faced with habitat alteration, changing climate and weather patterns, changing community interactions, novel resources, novel dangers, and a host of other natural and anthropogenic challenges. Conservationists endeavor to understand how changing ecology will impact local populations and local communities so efforts and funds can be allocated to those taxa/ecosystems exhibiting the greatest need. Ecological morphological and functional morphological research form the foundation of our understanding of selection-driven morphological evolution. Studies which identify and describe ecomorphological or functional morphological relationships will improve our fundamental understanding of how taxa respond to ecological selective pressures and will improve our ability to identify and conserve those aspects of nature unable to cope with rapid change. The New World wood warblers (family Parulidae) exhibit extensive taxonomic, behavioral, ecological, and morphological variation. -
21 Sep 2018 Lists of Victims and Hosts of the Parasitic
version: 21 Sep 2018 Lists of victims and hosts of the parasitic cowbirds (Molothrus). Peter E. Lowther, Field Museum Brood parasitism is an awkward term to describe an interaction between two species in which, as in predator-prey relationships, one species gains at the expense of the other. Brood parasites "prey" upon parental care. Victimized species usually have reduced breeding success, partly because of the additional cost of caring for alien eggs and young, and partly because of the behavior of brood parasites (both adults and young) which may directly and adversely affect the survival of the victim's own eggs or young. About 1% of all bird species, among 7 families, are brood parasites. The 5 species of brood parasitic “cowbirds” are currently all treated as members of the genus Molothrus. Host selection is an active process. Not all species co-occurring with brood parasites are equally likely to be selected nor are they of equal quality as hosts. Rather, to varying degrees, brood parasites are specialized for certain categories of hosts. Brood parasites may rely on a single host species to rear their young or may distribute their eggs among many species, seemingly without regard to any characteristics of potential hosts. Lists of species are not the best means to describe interactions between a brood parasitic species and its hosts. Such lists do not necessarily reflect the taxonomy used by the brood parasites themselves nor do they accurately reflect the complex interactions within bird communities (see Ortega 1998: 183-184). Host lists do, however, offer some insight into the process of host selection and do emphasize the wide variety of features than can impact on host selection. -
Rio Negro Paradise: Manaus I 2016

Wing-banded Wren was one of the many rainforest understory prizes on this tour. Photo by guide Marcelo Padua. The rhythm of life in the Amazon is largely dictated by water; the levels of the rivers and amount of rainfall influence everything. And rain was a theme on this particular tour! We ran into an unexpected amount of rainfall during our first days that cost us some valuable birding time (and species) in terra firme forest. On the positive side, however, it also meant that ant swarms were more active, and we ended up getting some remarkable views of scarce obligate ant-followers that we miss most years, such as White-plumed Antbird and Rufous-throated Antbird. The heavy rains prevented us from reaching the tower on our way to Presidente Figueiredo, but we bounced back from it by visiting a nearby road and pulling in some fabulous canopy flocks and great birds including the usually scarce Dotted Tanager as well as the incredibly handsome Paradise Tanager. Then, thanks largely Bret Whitney's help, we were able to secure a couple of 4x4 vehicles and visit the tower instead on our way back to Manaus. At Presidente Figueiredo our updated itinerary meant we were staying in a lodge instead of the hammock camp previously used, and so we were able to take advantage of a Guianan Cock-of-the-rock lek just a few minutes from the lodge and even had them showing up around the dining area, where they fed in palm trees along with toucans and aracaris. -
Colombia: from the Choco to Amazonia
This gorgeous Cinnamon Screech Owl narrowly missed being our bird-of-the-trip! (Pete Morris) COLOMBIA: FROM THE CHOCO TO AMAZONIA 9/12/15 JANUARY – 5/11 FEBRUARY 2016 LEADER: PETE MORRIS Well, this was the first time that we had run our revised Colombia With a Difference tour – now aptly-named Colombia: From the Choco to Amazonia. Complete with all the trimmings, which included pre-tour visits to San Andres and Providencia, the Sooty-capped Puffbird Extension, and the post tour Mitu Extension, we managed to amass in excess of 850 species. Travelling to the Caribbean, the Pacific Coast, the High Andes and the Amazon all in one trip really was quite an experience, and the variety and diversity of species recorded, at times, almost overwhelming! Picking out just a few highlights from such a long list is difficult, but here’s just an 1 BirdQuest Tour Report:Colombia: From the Choco to Amazonia www.birdquest-tours.com The exquisite Golden-bellied Starfrontlet, one of a number of stunning hummers and our bird-of-the-trip!

The Sooty-capped Puffbirds were all we hoped for and a male Sapphire-bellied Hummingbird a bonus! A sneaky trip to Sumapaz National Park yielded several Green-bearded Helmetcrests and Bronze-tailed Thorn- bill. On the main tour we saw a huge number of goodies. Blue-throated, Dusky and Golden-bellied Starfrontlets (all stunners!); the rare Humboldt’s Sapphire was a Birdquest lifer; nightbirds included Black-and-white Owl and White-throated, Cinnamon and Choco Screech Owls; and a random selection of other favourites included Gorgeted Wood Quail, the much appreciated Brown Wood Rail, Beautiful Woodpecker, Chestnut-bellied Hum- mingbird, Black Inca, the brilliant Rusty-faced Parrot, Citron-throated Toucan, Recurve-billed Bushbird, Urrao Antpitta, Niceforo’s and Antioquia Wrens, the amazing Baudo Oropendola, Crested and Sooty Ant Tanagers and the rare Mountain Grackle. -

Amazon Cruise - Primates & Parrots Trip Report and Systematic List 28 April – 10 May 2019 Text by Chris Collins with Assistance from Regina Ribeiro
Amazon Cruise - Primates & Parrots Trip Report and Systematic List 28 April – 10 May 2019 Text by Chris Collins with assistance from Regina Ribeiro. Photos by Chris Collins except where indicated. Introduction This was the second of our “world first” Amazon Primates and Parrots wildlife cruises and like the inaugural trip in 2018, the expedition was a great success with many poorly known species being seen. We spent most of the time exploring the remote rainforests south of the Amazon between Manaus and Santarem (with a couple of days north of this mighty river towards the end of the tour) giving us access to the home ranges of many highly localised primates. For many of the group, the marmosets were amongst the most desired species and we had considerably success finding five species including Golden-white Tassel-ear, Maués, Sateré and Santarem. We were equally successful with the titi monkeys and our sightings included Lake Baptista, Red-bellied, Chestnut-bellied and Ashy. With other primates including Martin’s Bare-faced Tamarin, Red-nosed Saki, Spix’s Howler, Spix’s Black-headed Uacari, the total for the main tour was 26 species, with a further five being seen on the extension to Uacari Lodge. The mammals found also included other families than just primates and we had good views of Brown-throated and Linnaeus’s Two-toed Sloths, as well as Brazilian Porcupine and more or less daily sightings of both Tucuxi and Amazon River Dolphin. Indeed, for some of the group our visit to a site near Manaus where it was possible to ‘swim’ with wild dolphins was a major highlight of the tour.
