Researchers Document Aviary Eggshell with Iridescence for the First Time 10 December 2014, by Bob Yirka
Researchers document aviary eggshell with iridescence for the first time 10 December 2014, by Bob Yirka they found to be made of calcium phosphate, calcium carbonate, and some other yet to be identified organic compounds) which gave the egg its glossy sheen. When they removed the cuticle from a portion of an egg sample—they found that it was blue underneath, but that the iridescence was gone. Thus, they concluded that the iridescent blue was due to a combination of the pigment and Photographs (a–c) of T. major, E. elegans and N. cuticle. maculosa nests.

Continued Bird Surveys in Southeastern Coastal Brazilian Atlantic Forests and the Importance of Conserving Elevational Gradients
Revista Brasileira de Ornitologia, 22(4), 383-409 ARTICLE December 2014 Continued bird surveys in southeastern coastal Brazilian Atlantic forests and the importance of conserving elevational gradients Vagner Cavarzere1,2,4, Thiago Vernaschi Vieira da Costa1,2, Giulyana Althmann Benedicto3, Luciano Moreira-Lima1,2 and Luís Fábio Silveira2 1 Pós-Graduação, Departamento de Zoologia, Instituto de Biociências, Universidade de São Paulo.

Accepted on 18 November 2014. ABSTRACT: Although the Atlantic forest is the best-studied Brazilian phytogeographic domain, few coastal municipalities of the state of São Paulo can count on published and critically revised bird species list, which are important initial steps to organize conservation inniciatives. Here we present historical records from Bertioga, a northern coastline municipality of the state of São Paulo, as well as recent records obtained in surveys during the past years within the municipality. Surveying methods, carried out between 2008-2011, included point counts, 10-species lists, transect counts and mist nets. This compendium resulted in 330 documented species, 90 of which still await documentation. Of these 420 bird species, 85 (20.4%) are Atlantic forest endemic species and as many as eight, six and 23 are threatened at the global, national and state levels, respectively. Seventeen species are reported from Bertioga for the first time. -
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. -
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. -

Bogota, the Magdalena Valley & Santa
® field guides BIRDING TOURS WORLDWIDE [email protected] • 800•728•4953 ITINERARY COLOMBIA: BOGOTA, THE MAGDALENA VALLEY & SANTA MARTA January 9-24, 2021 One of the range-restricted species we’ll seek on this tour is the Rusty-breasted Antpitta. These tiny ground-dwellers are found in the mountains of northern Colombia and Venezuela. We’ll look for this skulker in the Sierra Nevada de Santa Marta. Photograph by guide Jesse Fagan. We include here information for those interested in the 2021 Field Guides Colombia: Bogota, the Magdalena Valley & Santa Marta tour: ¾ a general introduction to the tour ¾ a description of the birding areas to be visited on the tour ¾ an abbreviated daily itinerary with some indication of the nature of each day’s birding outings These additional materials will be made available to those who register for the tour: ¾ an annotated list of the birds recorded on a previous year’s Field Guides trip to the area, with comments by guide(s) on notable species or sightings (may be downloaded from our web site) ¾ a detailed information bulletin with important logistical information and answers to questions regarding accommodations, air arrangements, clothing, currency, customs and immigration, documents, health precautions, and personal items ¾ a reference list ¾ a Field Guides checklist for preparing for and keeping track of the birds we see on the tour ¾ after the conclusion of the tour, a list of birds seen on the tour 1900+ species. Subtract the species recorded on that archipelago off Central America (San Andres, if you care), and Colombia is still ahead of Brazil and Peru, let alone our most popular South American destination, Ecuador, which is several hundred species behind. -
TAS Trinidad and Tobago Birding Tour June 14-24, 2012 Brian Rapoza, Tour Leader
TAS Trinidad and Tobago Birding Tour June 14-24, 2012 Brian Rapoza, Tour Leader This past June 14-24, a group of nine birders and photographers (TAS President Joe Barros, along with Kathy Burkhart, Ann Wiley, Barbara and Ted Center, Nancy and Bruce Moreland and Lori and Tony Pasko) joined me for Tropical Audubon’s birding tour to Trinidad and Tobago. We were also joined by Mark Lopez, a turtle-monitoring colleague of Ann’s, for the first four days of the tour. The islands, which I first visited in 2008, are located between Venezuela and Grenada, at the southern end of the Lesser Antilles, and are home to a distinctly South American avifauna, with over 470 species recorded. The avifauna is sometimes referred to as a Whitman’s sampler of tropical birding, in that most neotropical bird families are represented on the islands by at least one species, but never by an overwhelming number, making for an ideal introduction for birders with limited experience in the tropics. The bird list includes two endemics, the critically endangered Trinidad Piping Guan and the beautiful yet considerably more common Trinidad Motmot; we would see both during our tour. Upon our arrival in Port of Spain, Trinidad and Tobago’s capital, we were met by the father and son team of Roodal and Dave Ramlal, our drivers and bird guides during our stay in Trinidad. Ruddy Ground-Dove, Gray- breasted Martin, White-winged Swallow and Carib Grackle were among the first birds encountered around the airport. We were immediately driven to Asa Wright Nature Centre, in the Arima Valley of Trinidad’s Northern Range, our base of operations for the first seven nights of our tour. -
FIELD GUIDES BIRDING TOURS: Colombia: Bogota, the Magdalena
Field Guides Tour Report Colombia: Bogota, the Magdalena Valley, and Santa Marta 2014 Jan 11, 2014 to Jan 27, 2014 Jesse Fagan & Trevor Ellery For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. A fun group and the most productive tour we have had to date! We observed 582 bird taxa in 17 days of birding, which beat our record last year of 555 by a bunch. As we fine-tune our birding route and learn more about Colombian birds things just seem to get better and better. This year we saw 33 endemics and loads of interesting subspecies and near-endemics. Highlights included a female Blue- billed Curassow, Kelp Gull(s) at Los Camerones (only the second time it has been recorded in Colombia), Dwarf and Pavonine cuckoos (the latter a lifer for Trevor!), a splendid Crested Owl, Sapphire- bellied Hummingbird (nice comparisons with Sapphire-throated), Double-banded Graytail in the coffee finca below Reinita Cielo Azul lodge, the always elusive Santa Marta Bush-Tyrant and antpitta, Turquoise Dacnis, and singing Yellow-bellied Siskin. It is really hard to pick just one from so many! I want to thank all of you again for a really enjoyable trip. Thanks also to Trevor Ellery, our local guide, and Giovanni, our driver, for their hard work. I look forward to seeing you again in the field. Bird On. --Jesse a.k.a.
