Reportamos la observación de un macho adulto de Trogon collaris con vientre amarillo, similar al color del vientre de Trogon violaceus o Trogon melanocephalus. El pico era de color amarillo sucio y el anillo orbital era oscuro. Con base en publicaciones sobre coloración anormal en otras especies, asumimos que fueron alteraciones genéticas o de desarrollo del individuo las que causaron el color amarillo en lugar del rojo usual del plumaje ventral. Collared Trogon (Trogon collaris) occurs in several disjunct areas from central Mexico to the northern half of South America east of the Andes (AOU 1998. Check-list of North American birds. 7th ed.

In both observations, a male and female rapidly raised their tails to a horizontal position and slowly returned them to a vertical hanging position. During these displays, both individuals simultaneously emitted loud calls approximately every 5 seconds, forming a duet. The first display lasted 30 minutes while the second lasted approximately 45 minutes. This `raised tail' behavior has been reported for several species of trogons during courtship and when mobbing a predator. Because there were no predators present during both observations, the described `raised tail' behavior was most likely a courtship display. -
Life History of the Black-Throated Trogon
LIFE HISTORY OF THE BLACK-THROATED TROGON BY ALEXANDER F. SKUTCH N Barro Colorado Island in Gatlin Lake, in the middle of the Isthmus of 0 Panama, I found my first twTo nests of the Black-throated Trogon (Trogon rufus) , in 1935. Both were destroyed by predators before the eggs hatched. Four years later, in the Valley of El General in southern Costa Rica, I found my third nest, which met a similar fate. In most of the succeeding years I have studied birds in the same region, where these trogons are not uncommon, and I have encountered five additional nests. With the exception of one which I did not see until the young were almost feathered, only the last was successful. This was situated on our farm in El General in April, 1958, and enabled me to round out a study begun 23 years earlier. The present paper is, then, a report of observations gathered over nearly a quarter of a century. The slowness of their accumulation is to be attributed to the diffi- culty of finding the nests of the majority of the birds that dwell in tropical rain-forest, and the discouragingly small proportion of these nests that yield living young. APPEARANCE AND RANGE One of the smaller members of its family, the Black-throated Trogon has a total length of about nine inches, of which well over half is accounted for by its long tail. The males’ predominant color is bright metallic green, which covers all the upper surface of head and body and likewise the chest. -

Linking Shade Coffee Certification to Biodiversity Conservation: Butterflies and Birds in Chiapas, Mexico
Ecological Applications, 14(3), 2004, pp. 642±654 q 2004 by the Ecological Society of America LINKING SHADE COFFEE CERTIFICATION TO BIODIVERSITY CONSERVATION: BUTTERFLIES AND BIRDS IN CHIAPAS, MEXICO ALEXANDRE H. MAS AND THOMAS V. D IETSCH1 School of Natural Resources and Environment, University of Michigan, Ann Arbor, Michigan 48109-1115 USA Abstract. Shade coffee certi®cation programs have emerged over the past six years to verify that coffee marketed as ``shade grown'' is actually grown on farms that provide higher quality habitat for biodiversity. In spite of good intentions and an increasing market, little consensus exists on whether current criteria can successfully identify coffee farms of conservation signi®cance. This paper provides the ®rst ecological evaluation and compar- ison of shade-grown coffee criteria used by major certi®cation programs. Using vegetative data, we evaluated criteria developed by the Rainforest Alliance, the Smithsonian Migratory Bird Center (SMBC), and the Specialty Coffee Association of America across a range of coffee agroecosystems in Chiapas, Mexico, to determine which management practices each program would certify. Fruit-feeding butter¯ies and forest bird species found in these coffee agroecosystems were compared with nearby forest reserves as indicators of biodiversity and conservation potential. These agroecosystems fall into three categories: rustic, com- mercial polyculture, and shaded monoculture. The rustic system contained signi®cantly higher fruit-feeding butter¯y diversity and an avifauna more similar to that found in forest reserves than the other systems. This was also the only agroecosystem that met the criteria for all certi®cation programs, while the shaded monoculture fell short of all sets of criteria. -
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.

Bare-crowned Antbird Tour Intro Colombia has become iconic among Neotropical bird enthusiasts…that is to say, anybody who has ever seen a Cock-of-the-rock, Manakin lek, or hummingbird feeding station in the Andes! It is impossible to avoid falling in love with this diverse, impressive, stunning part of the world – and Colombia has the best of it. Guianan shield, Amazon Basin, three Andean ranges, tropical valleys, coastlines, and the famed Santa Marta Mountains are only what is NOW recognized as accessible. As time passes, access increases, and Colombia (rather than becoming more mundane) just becomes more mysterious as new species reveal themselves and new habitats become known, and we look to ever more remote parts of this complex nation. The mystery and wonder of Colombia, perhaps more than any other country, begged a challenge: is it possible for a commercial tour to record more than 1000 species of birds in less than a month? If so, Colombia was obviously the place to do it! The following is a much abbreviated account of one of the most spectacular journeys this author has ever embarked upon, and cannot possibly do justice to the marvelous sights, sounds, smells, and tastes one encounters after spending a whole month in Birder’s Paradise – Colombia! Tour Summary We all congregated in Colombia’s cosmopolitan capitol city Santa Fe de Bogota, on November 22nd, 2013. -

Mammalian and avian diversity of the Rewa Head, Rupununi, Southern Guyana. Biota Neotrop. 11(3): http://www.biotaneotropica.org.br/v11n3/en/abstract?in ventory+bn00911032011 Abstract: We report the results of a short expedition to the remote headwaters of the River Rewa, a tributary of the River Essequibo in the Rupununi, Southern Guyana. We used a combination of camera trapping, mist netting and spot count surveys to document the mammalian and avian diversity found in the region. We recorded a total of 33 mammal species including all 8 of Guyana’s monkey species as well as threatened species such as lowland tapir (Tapirus terrestris), giant otter (Pteronura brasiliensis) and bush dog (Speothos venaticus). We recorded a minimum population size of 35 giant otters in five packs along the 95 km of river surveyed. In total we observed 193 bird species from 47 families. With the inclusion of Smithsonian Institution data from 2006, the bird species list for the Rewa Head rises to 250 from 54 families. These include 10 Guiana Shield endemics and two species recorded as rare throughout their ranges: the harpy eagle (Harpia harpyja) and crested eagle (Morphnus guianensis). -

Late evening departure. August 14 Lima to Cusco to Huacarpay Lake After an early breakfast in Peru’s capital Lima, we took a flight to the Andean city of Cusco. Soon after arriving in Cusco and meeting with our driver we headed out to Huacarpay Lake . Unfortunately our arrival time meant we got there when it was really hot, and activity subsequently low. Although we stuck to it, and slowly but surely, we managed to pick up some good birds. On the lake itself we picked out Puna Teal, Speckled and Cinnamon Teals, Andean (Slate-colored) Coot, White-tufted Grebe, Andean Gull, Yellow-billed Pintail, and even Plumbeous Rails, some of which were seen bizarrely swimming on the lake itself, something I had never seen before. -
