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.

Iridescent plumage colors are produced by nanostructures in 10 feathers and have evolved in a wide variety of birds. The building blocks of these 11 structures—melanosomes (melanin-filled organelles)—come in a variety of forms, yet how 12 these different forms contribute to color production across birds remains unclear. Here, we 13 leverage evolutionary analyses, optical simulations and reflectance spectrophotometry to 14 uncover general principles that govern the production of brilliant iridescence. We find that a 15 key feature that unites all melanosome forms in brilliant iridescent structures is thin melanin 16 layers. Birds have achieved this in multiple ways: by decreasing the size of the melanosome 17 directly, by hollowing out the interior, or by flattening the melanosome into a platelet. The 18 evolution of thin melanin layers unlocks color-producing possibilities, more than doubling 19 the range of colors that can be produced with a thick melanin layer and simultaneously 20 increasing brightness. -

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. -

Elegant Trogon (Trogon Elegans)
Elegant Trogon (Trogon elegans) NMPIF level: Biodiversity Conservation Concern, Level 1 (BC1) NMPIF assessment score: 16 NM stewardship responsibility: Low National PIF status: Watch List New Mexico BCRs: 34 Primary breeding habitat(s): Southwest Riparian Other habitats used: Madrean Pine-Oak Woodland (foraging) Summary of Concern Elegant Trogon is primarily a Mexican species with a limited breeding population in several mountain ranges of southeast Arizona, with at most a few pair breeding regularly in the Peloncillo Mountains of New Mexico. It requires moist riparian canyons with a sycamore component and upland areas of arid woodland. Associated Species Zone-tailed Hawk, Elf Owl (SC1), Black-chinned Hummingbird (SC2), Arizona Woodpecker (BC2), Northern Flicker, Dusky-capped Flycatcher, Hepatic Tanager, Brown-crested Flycatcher, Magnificent Hummingbird (BC2) Distribution Elegant Trogon is resident along the Pacific slope of Mexico from Sonora to Oaxaca, and in eastern Mexico from central Tamaulipas and southeast Nuevo León south to Puebla and Oaxaca (Howell and Webb 1995). A separate population is also resident in portions of Guatemala, El Salvador, and the interior of Honduras, south to Costa Rica. In summer, the breeding range extends a fairly short distance north into southeast Arizona. In New Mexico, this species is present only in the Peloncillo Mountains in southwest Hidalgo County (Kunzmann et al. 1998, Parmeter et al. 2002). Ecology and Habitat Requirements Across its range in Mexico and Central America, Elegant Trogon occupies a range of lowland, foothill and mountain habitats, including high elevation montane forests, semi-arid pine-oak woodland, lowland tropical deciduous forest and thorn forest. In southeast Arizona, where breeding populations have been studied, it is associated with sycamore- or high-elevation cottonwood-dominated riparian vegetation in a surrounding matrix of pinyon-juniper, pine-oak woodland or upland forest (Kunzmann et al. -

Santa Rita Mountains Elegant Trogon Census Census Date
Santa Rita Mountains Elegant Trogon Census Census Date: Sunday May 24, 2020 Census Time: 6 to 11 a.m. Pre-survey: Zoom meeting before survey online – details sent via email Any and all questions pertaining to the census will be welcome in the zoom email. On the aziba.org website are recordings of several types of Elegant Trogon calls to help counters recognize trogon vocalizations--if and when they hear them. They are also posted on the Arizona IBA website here: http://aziba.org/?page_id=1994 - The mp3 file beginning with Koink is the common call heard most often – it is likely a male advertising his territory or trying to attract a female. This certainly indicates you have a male but you cannot infer a pair from this call necessarily. - The mp3 file beginning with Kow – you should listen to this one carefully – note the lack of space between each note, it is much more continuous than the Koink call. This does indicate a mated pair and I have sometimes heard both the male and female giving this call to each other. Her voice is considerably lower than his. - The mp3 file beginning with W-kkk – this is an alarm call and it means the Trogons are distressed and you are likely very close to their nest. Back off immediately if you hear this sound. Wait a while and then cautiously try to find the nest if it is possible to do so without alarming the trogons. Counters need to have a watch or a clock with them during the survey to fill out the time forms. -
Annual Report 2007 AMERICAN BIRD CONSERVANCY from the Chairman and the President
Annual Report 2007 AMERICAN BIRD CONSERVANCY From the Chairman and the President In the Catbird Seat Gray Catbird: Greg Lavaty member recently mentioned that he thought the threats to birds and what is being done to overcome American Bird Conservancy is “in the catbird them. Please have a look at BNN on ABC’s website, seat.” This saying, popularized by the writer, www.abcbirds.org—we guarantee you’ll enjoy it. AJames Thurber, is generally used to mean one is in a high, prominent, and advantageous position, and so we were Your support is fundamental to our success, and it has flattered by the compliment. In nature, though, it is more increased exponentially through your support of ABC’s often the mockingbird that sits high and visible for all to American Birds Campaign, a drive based on measurable see, while the catbird makes a big stir but remains hidden conservation outcomes. We are pleased to report, at deep in the bushes. Maybe this is even truer of ABC— the campaign’s halfway point, that we are well past our always effective but not always seen! expectations in protecting birds and their habitats! Thank you for being on our team! Recently the New York Times Magazine described ABC as “a smaller, feistier group.” We are proud of being small, But despite what we have already achieved with your nimble, and at the same time feisty in the defense of birds help, ABC is just getting started.

Species List February 20 ‒ 28, 2019 | Written by Bob Meinke
Southern Belize: Birding & Nature | Species List February 20 ‒ 28, 2019 | Written by Bob Meinke Guide Bob Meinke, with expert local lodge naturalists Marvin and Steven, and 9 participants: Kelly, Isaac, Lenore, Harold, Cindy, Richelle, Beth, Nancy, and Joe SUMMARY We enjoyed a scenic and productive trip, starting with the vast freshwater wetlands at Crooked Tree Lagoon, transitioning on to the montane woodlands of the Mountain Pine Ridge, and ending our tour in the broadleaf forests and mangroves of Toledo District at the southern tip of Belize. Working our way down the length of the country increased our exposure to a wide range of habitats, and with it came a nice assortment of resident and migrant bird species as well as other wildlife. Highlights among the resident species included King Vulture, Bare-crowned Antbird, Black-and-white Owl, Yucatan Jay, White-winged Becard, Ruddy Woodcreeper, Eye-ringed Flatbill, Violet Sabrewing, three species of Trogon, and five species of Kingfisher (with multiple, close-in views of American Pygmy a surprising bonus). And while not unexpected, Keel-billed Toucan, Collared Aracari, Bare-throated Tiger Heron, Montezuma Oropendola, Golden -headed Tanager, Barred Antshrike, and Squirrel Cuckoo were all exquisite reminders of the rich colors and morphological diversity that characterize the avifauna of the Neotropics. North American migrants were also plentiful during our visit, and among the many warblers encountered, Blue-winged, Worm-eating, and Prothonotary stood out among the 21 overwintering species we recorded, most of which were just entering full breeding plumage as they readied for their journey north to the U.S.
