Orange-crowned Warbler
The orange-crowned warbler (''Leiothlypis celata'') is a small songbird of the New World warbler family. Taxonomy The orange-crowned warbler was formally described in 1822 by the American zoologist Thomas Say under the binomial name ''Sylvia celatus'' from a specimen collected on an expedition from Pittsburgh to the Rocky Mountains led by Stephen Harriman Long. The specific epithet ''celatus'' is Latin and means "secret" or "hidden". The type locality is Omaha, Nebraska. The orange-crowned warbler is now placed in the genus ''Leiothlypis'' that was introduced by the Dutch ornithologist George Sangster in 2008. The genus name is derived from the Ancient Greek λειος/''leios'' meaning "plain" and θλυπις/''thlupis'', an unknown small bird mentioned by Aristotle. Four subspecies are recognised: * ''L. c. celata'' ( Say, 1822) – breeds in central Alaska to south Canada, winters in Guatemala * ''L. c. lutescens'' ( Ridgway, 1872) – breeds in west Canada and west USA, wi ...

Thomas Say
Thomas Say (June 27, 1787 – October 10, 1834) was an American entomologist, conchologist, and Herpetology, herpetologist. His studies of insects and shells, numerous contributions to scientific journals, and scientific expeditions to Florida, Georgia, the Rocky Mountains, Mexico, and elsewhere made him an internationally known naturalist. Say has been called the father of American descriptive entomology and American conchology. He served as librarian for the Academy of Natural Sciences of Philadelphia, curator at the American Philosophical Society (elected in 1817), and professor of natural history at the University of Pennsylvania. Early life and education Born in Philadelphia into a prominent Religious Society of Friends, Quaker family, Thomas Say was the great-grandson of John Bartram, and the great-nephew of William Bartram. His father, Dr. Benjamin Say, was brother-in-law to another Bartram son, Moses Bartram. The Say family had a house, "The Cliffs" at Gray's Ferry Bridge, ...

Robert Ridgway
Robert Ridgway (July 2, 1850 – March 25, 1929) was an American ornithologist specializing in systematics. He was appointed in 1880 by Spencer Fullerton Baird, secretary of the Smithsonian Institution, to be the first full-time curator of birds at the United States National Museum, a title he held until his death. In 1883, he helped found the American Ornithologists' Union, where he served as officer and journal editor. Ridgway was an outstanding descriptive taxonomist, capping his life work with ''The Birds of North and Middle America'' (eight volumes, 1901–1919). In his lifetime, he was unmatched in the number of North American bird species that he species description, described for science. As technical illustrator, Ridgway used his own paintings and outline drawings to complement his writing. He also published two books that systematized color names for describing birds, ''A Nomenclature of Colors for Naturalists'' (1886) and ''Color Standards and Color Nomenclature'' ...

Birds Of North America
The lists of birds in the light blue box below are divided by biological family. The lists are based on ''The AOS Check-list of North American Birds'' of the American Ornithological Society and ''The Clements Checklist of Birds of the World'' supplemented with checklists from Panama, Greenland, and Bermuda. It includes the birds of Greenland, Canada, the United States (excluding Hawaii), Mexico, Central America, Bermuda, and the West Indies. Taxonomy The taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) used in the accompanying bird lists adheres to the conventions of the AOS's (2019) ''Check-list of North American Birds'', the recognized scientific authority on the taxonomy and nomenclature of North America birds. The AOS's Committee on Classification and Nomenclature, the body responsible for maintaining and updating the ''Check-list'', "strongly and unanimously continues to endorse the biological spe ...

Bird Migration
Bird migration is a seasonal movement of birds between breeding and wintering grounds that occurs twice a year. It is typically from north to south or from south to north. Animal migration, Migration is inherently risky, due to predation and mortality. The Arctic tern holds the long-distance migration record for birds, travelling between Arctic breeding grounds and the Antarctic each year. Some species of Procellariiformes, tubenoses, such as albatrosses, circle the Earth, flying over the southern oceans, while others such as Manx shearwaters migrate between their northern breeding grounds and the southern ocean. Shorter migrations are common, while longer ones are not. The shorter migrations include altitudinal migrations on mountains, including the Andes and Himalayas. The timing of migration seems to be controlled primarily by changes in day length. Migrating birds navigate using celestial cues from the Sun and stars, the Earth's magnetic field, and mental maps.

Alaska
Alaska ( ) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is also considered to be the northernmost, westernmost, and easternmost (the Aleutian Islands cross the 180th meridian into the eastern hemisphere) state in the United States. It borders the Canadian territory of Yukon and the province of British Columbia to the east. It shares a western maritime border, in the Bering Strait, with Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south. Technically, it is a semi-exclave of the U.S., and is the largest exclave in the world. Alaska is the largest U.S. state by area, comprising more total area than the following three largest states of Texas, California, and Montana combined, and is the seventh-largest subnational division i ...

Bird Measurement
Bird measurement or bird biometrics are approaches to quantify the size of birds in scientific studies. The variation in dimensions and weights across birds is one of the fundamental sources of diversity among birds, and even Within species, dimensions may vary across populations Intraspecific variability, within species, between the sexes and depending on Biomarkers of aging, age and condition. For measurements to be useful, they must be well-defined to be consistent and comparable with those taken by others or at other points in time. Measurements can be useful to identify species, quantify functional and ecomorphology, ecomorphological differences, study growth, variation between geographically separated forms, identify Sexual dimorphism measures, differences between the sexes, age or otherwise characterize individual birds. While certain measurements are regularly taken to study living birds, others apply only to specimens in bird collections or are measurable only in the labo ...

Black-throated Blue Warbler
The black-throated blue warbler (''Setophaga caerulescens'') is a small passerine bird of the New World warbler family. Its breeding ranges are located in the interior of deciduous and mixed coniferous forests in eastern North America. Over the cooler months, it bird migration, migrates to islands in the Caribbean and Central America. It is very rarely found in western Europe, where it is considered to be a non-indigenous species. The black-throated blue warbler is sexually dimorphic; the adult male has a black face and cheeks, deep blue upperparts and white underparts, while the adult female is olive-brown above and light yellow below. Predominantly insectivore, insectivorous, the black-throated blue warbler supplements its diet with berries and seeds in winter. It builds its nests in thick shrubs and the closeness of its nesting sites to the ground make it a favored species for the study of warbler behavior in the wild. The black-throated blue warbler defends its territory agai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tennessee Warbler
The Tennessee warbler (''Leiothlypis peregrina'') is a New World warbler that breeds in eastern North America and winters in southern Central America, the Caribbean, and northern South America.
