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.

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. -

The Birds of Hacienda Palo Verde, Guanacaste, Costa Rica PAUL SLUD SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 292 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoo/ogy Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world cf science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. Press requirements for manuscript and art preparation are outlined on the inside back cover. -
Wood Warblers of Lake County (Field Guide)
Wood of Lake County An educational wildlife pamphlet provided by the Lake County Public Resources Department Parks & Trails Division 2 The Lake County Public Resources Department, Parks & Trails Division, manages more than three dozen parks, preserves and boat ramps. Lake County park rangers lead regularly scheduled nature in some of these parks. In partnership with the Lake County hikes, bird and butterfly surveys and other outdoor adventures Water Authority, Parks & Trails also schedules guided paddling adventures. For a listing of Lake County parks and events, call 352-253-4950, email [email protected] or visit Forwww.lakecountyfl.gov/parks. more information about birds that can be seen in Lake County, or bookstores. Information on birds is also available online at the check out a field guide to birds available at many local libraries Cornell Laboratory of Ornithology, www.birds.cornell.edu. Bird watchers in Florida tend to bring a little more on their trips than their Northern peers. While the average temperature in Lake County is a mild 72°F, the summer months in Central Florida can be steamy. Outside enthusiasts are always encouraged to carry sunscreen to protect skin from sunburn, insect repellent to ward off mosquitoes and plenty of water to avoid dehydration. Sunscreen should be 15 SPF or higher and applied 20 minutes before. 3 Park rangers recommend these six popular comprehensive guides: • A Field Guide to the Birds, Eastern and Central North America (Fourth Edition, 1980, Roger Tory Peterson) • Stokes Field Guide to Birds, Eastern Region (First Edition, 1996, Donald and Lillian Stokes) • All the Birds of North America (First Edition, 1997, The American Bird Conservancy) • Field Guide to the Birds of North America (Fourth Edition, 2002, The National Geographic Society) • Focus Guide to the Birds of North America (First Edition, 2000, Kenn Kaufman) • The Sibley Guide to Birds (First Edition, 2000, David Allen Sibley) Insect repellent should contain DEET. -
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. -
Macgillivrays Warbler
Wyoming Species Account MacGillivray’s Warbler Geothlypis tolmiei REGULATORY STATUS USFWS: Migratory Bird USFS R2: No special status USFS R4: No special status Wyoming BLM: No special status State of Wyoming: Protected Bird CONSERVATION RANKS USFWS: No special status WGFD: NSS4 (Bc), Tier II WYNDD: G5, S4 Wyoming Contribution: LOW IUCN: Least Concern PIF Continental Concern Score: 11 STATUS AND RANK COMMENTS MacGillivray’s Warbler (Geothlypis tolmiei) does not have any additional regulatory status or conservation rank considerations beyond those listed above. NATURAL HISTORY Taxonomy: Two subspecies of MacGillivray’s Warbler are recognized and known to breed in the United States: G. t. tolmiei and G. t. monticola 1. In Wyoming, G. t. monticola is the known subspecies; it breeds east of the Pacific slope, in the Rocky Mountains and Great Basin, and winters in higher elevations of central and southern Mexico, occasionally in southern California 2, 3. Two additional subspecies of G. tolmiei are not recognized by the American Ornithologists’ Union (AOU): G. t. intermedia and G. t. austinsmithi. The distinguishing characteristic is reported to be a shorter tail length in G. t. austinsmithi and there are specimens of said subspecies from western Wyoming 1, 4. Recent molecular phylogeny efforts concluded that MacGillivray’s Warbler is more closely related to the genus Geothlypis 5. The AOU approved the genus change in 2011 6. Prior to this, the species was placed in the genus Oporornis. Description: The species is a small wood-warbler in the Parulidae Family. MacGillivray’s Warbler is identifiable in the field during the breeding season. Male upperparts are olive green and underparts are yellow. -

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. -
