E-mail: [email protected] Abstract We investigated if passerine birds act as important predators of small vertebrates within the Neotropics. We surveyed published studies on bird diets, and information on labels of museum specimens, compiling data on the contents of 5,221 stomachs. Eighteen samples (0.3%) presented evidence of predation on vertebrates. Our bibliographic survey also provided records of 203 passerine species preying upon vertebrates, mainly frogs and lizards. Our data suggest that vertebrate predation by passerines is relatively uncommon in the Neotropics and not characteristic of any family. On the other hand, although rare, the ability to prey on vertebrates seems to be widely distributed among Neotropical passerines, which may respond opportunistically to the stimulus of a potential food item. -
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. -

Colombia Trip Report Santa Marta Extension 25Th to 30Th November 2014 (6 Days)
RBT Colombia: Santa Marta Extension Trip Report - 2014 1 Colombia Trip Report Santa Marta Extension 25th to 30th November 2014 (6 days) Buffy Hummingbird by Clayton Burne Trip report compiled by tour leader: Clayton Burne RBT Colombia: Santa Marta Extension Trip Report - 2014 2 Our Santa Marta extension got off to a flying start with some unexpected birding on the first afternoon. Having arrived in Barranquilla earlier than expected, we wasted no time and headed out to the nearby Universidad del Norte – one of the best places to open our Endemics account. It took only a few minutes to find Chestnut- winged Chachalaca, and only a few more to obtain excellent views of a number of these typically localised birds. A fabulous welcome meal was then had on the 26th floor of our city skyscraper hotel! An early start the next day saw us leaving the city of Barranquilla for the nearby scrub of Caño Clarín. Our account opened quickly with a female Sapphire-throated Hummingbird followed by many Russet-throated Puffbirds. A Chestnut-winged Chachalaca by Clayton Burne White-tailed Nightjar was the surprise find of the morning. We added a number of typical species for the area including Caribbean Hornero, Scaled Dove, Green-and-rufous, Green and Ringed Kingfishers, Red-crowned, Red-rumped and Spot-breasted Woodpeckers, Stripe-backed and Bicolored Wrens, as well as Black-crested Antshrike. Having cleared up the common stuff, we headed off to Isla de Salamanca, a mangrove reserve that plays host to another very scarce endemic, the Sapphire-bellied Hummingbird. More good luck meant that the very first bird we saw after climbing out of the vehicle was the targeted bird itself. -
02 Jun 2015 Lists of Victims and Hosts of the Parasitic Cowbirds
Host Lists of Cowbirds 1 version: 02 Jun 2015 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 are brood parasites. 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. -

Colombia, February-March 2016
Tropical Birding Trip Report Colombia, February-March 2016 Colombia February 25th to March 10th, 2016 TOUR LEADER: Nick Athanas Report and photos by Nick Athanas White-whiskered Spinetail – bird of the trip! It had been a while since I had guided a Colombia trip, and I had forgotten how neat the birds were! This two week customized tour combined a Northern Colombia trip with some of the best sites in Central Colombia. The weather was beautiful, the birds were spectacular and cooperative, and most importantly we had a fun and friendly group; we all had a blast. Custom trips are a great option for groups of friends that like to travel together, and it really worked well this time. I really love that White-whiskered Spinetail was voted “bird of the trip” – it’s the only time I can remember a spinetail winning that honor – it’s an often unappreciated group, but this one is really special and we had point-blank views. Runner up was Santa Marta Antbird, which was also highly deserving as one of the newest splits of a truly www.tropicalbirding.com +1-409-515-9110 [email protected] Tropical Birding Trip Report Colombia, February-March 2016 amazing genus. Other favorites were Golden-winged Sparrow, Russet-throated Puffbird, Scarlet Ibis, Turquoise Dacnis, Blue-billed Curassow, Red-bellied Grackle, Sword-billed Hummer, Crested Owl, Chestnut Piculet, Striped Manakin, and shockingly, even a couple of tapaculos, which impressed some by showing amazingly well. We started off in the “megapolis” of Bogotá, which served as our base for the first few nights as we made day trips to nearby sites in the eastern cordillera of the Andes. -

Abstract Background: The typical antbirds (Thamnophilidae) form a monophyletic and diverse family of suboscine passerines that inhabit neotropical forests. However, the phylogenetic relationships within this assemblage are poorly understood. Herein, we present a hypothesis of the generic relationships of this group based on Bayesian inference analyses of two nuclear introns and the mitochondrial cytochrome b gene. -

Two non-sister clades in putative Cercomacra were uncovered: (1) the ‘nigricans’ clade (Cercomacra sensu stricto), formed by manu, brasiliana, cinerascens, melanaria, ferdinandi, carbonaria, and nigricans; and (2) the ‘tyrannina’ clade formed by nigrescens, laeta, parkeri, tyrannina, and serva. Sciaphylax was sister to the ‘tyrannina’ clade and this group was sister to a clade formed by Drymophila and Hypocnemis. This whole major clade then was sister to Cercomacra sensu stricto. Further work is needed to resolve the phylogenetic placement of brasiliana and cinerascens within Cercomacra, and the relationships within the ‘tyrannina’ clade. -
Tropical Birding Tour Report
BRAZIL: THE PANTANAL & AMAZON 26 July – 7 August 2009 Tour leader: Nick Athanas Report by Nick Athanas Photos by the author unless otherwise indicated. Photo below: Scarlet-headed Blackbird. It’s a hard combo to beat – the vast primeval Amazonian forests of Cristalino and the non-stop wildlife show of the Pantanal, where pretty much the only way to stop seeing stuff is to close your eyes. There’s also a bit of cerrado birding thrown in to add some spice and variety, where you can quickly see a bunch of neat birds not available elsewhere on the tour. This year, despite a harpy and the mega-diveristy of Cristalino Lodge, it was Pousada Piuval that stole the show. It has always been good, which is why it features in the itinerary, but this year it was just jaw-dropping, mind-blowingly out-of-this world incredible. There were birds literally everywhere you looked. Vast numbers of birds, insane daily species lists topping out at 174 seen on one day (maybe a TB record?), normally tough birds like Great Rufous Woodcreepers pretty much on the doorstep, and quite simply a huge amount of fun. Mammals got better as we went deeper into the Pantanal, with the likes of Ocelot , Giant Otter , Giant Anteater , and Brazilian Tapir all featuring. I apologize now for the brevity of this report – I’ve had an insane guiding schedule over the last few months, and only a few days before my next one begins. But that’s the way I like it. The Chapada dos Guimarães We spent a couple of days in and around this plateau just northeast of the city of Cuiabá. -
Birds of the Chapada Diamantina, Bahia, Brazil
Birds of the Chapada Diamantina, Bahia, Brazil Ricardo Parrini, Marcos A. Raposo, José Fernando Pacheco, André M. P. Carvalhães, Tadeu A. Melo Júnior, Paulo Sérgio M. Fonseca and Jeremy Minns Cotinga 11 (1999): 86–95 A avifauna da Chapada Diamantina é, ainda, muito pouco conhecida. O presente estudo visou estabelecer um quadro representativo da distribuição das aves dessa região pelos diferentes ambientes aí presentes. Para isso, foram efetuadas várias excursões a campo, que abrangeram um total de 19 localidades, onde foram registradas, por observação ou coleta, 359 espécies. Além da sua importância para o conhecimento da biogeografia das aves do Neotrópico, esse trabalho demonstra a importância da conservação dos hábitats locais, que vêm sofrendo com a expansão das atividades humanas na região. Introduction The avifauna of the Chapada Diamantina is surprisingly little-known. No specific study of the area has been undertaken and the only information concerning its birds is scattered through general reference works, e.g. Meyer de Schauensee5, Sick18,19 and Ridgely & Tudor14,15, or in surveys of nearby areas, such as those by Pinto8 and Gonzaga et al.3. As the various biomes of this geographical formation have already been subject to changes through the actions of man, particularly in the forested areas, thorough studies of the local fauna are urgently required. In order to undertake an adequate survey of the main biomes of this region, namely campos rupestres (arid mountain scrub), caatingas (arid lowland scrub), cerrados, gallery forests, humid forests (sensu Rizzini16) and humid areas in general, we made a number of trips to various parts of the Chapada (see map).
