Cerulean Warbler
The cerulean warbler (''Setophaga cerulea'') is a small songbird in the family Parulidae. It is a long-distance migrant, breeding in eastern North American hardwood forests. In the non-breeding season, it winters on the eastern slope of the Andes in South America, preferring subtropical forests. It displays strong sexual dichromatism: Adult males have cerulean blue and white , with a black necklace across the breast and black streaks on the back and flanks. Females and immature birds have bluish-green upperparts, a pale stripe over the eye, no streaking, and are yellow below. All have two white wing bars and a thin, pointed . The cerulean warbler is insectivorous and predominantly feeds on insect larvae, though it also takes winged insects. It forages for prey and nests high in forest canopies. Individuals are strongly territorial; males will defend areas of forests. Males arrive on breeding grounds about one to two weeks earlier than females. Breeding and incubation take pl ...

Alexander Wilson (ornithologist)
Alexander Wilson (July 6, 1766 – August 23, 1813) was a Scottish-American poet, ornithologist, naturalist, and illustrator. Identified by George Ord as the "Father of American Ornithology", Wilson is regarded as the greatest American ornithologist prior to Audubon. Biography Early life Wilson was born in Paisley, Scotland on July 6, 1766. He was apprenticed as a weaver in 1779. Poetry and emigration While working as a weaver in Paisley, Wilson became seriously interested in poetry. He was inspired by the dialect verse of Robert Burns, who was only seven years older. He was close friends with fellow Paisley poet Ebenezer Picken. In addition to ballads and pastoral pieces, Wilson wrote satirical commentary on the conditions of weavers in the mills. His authorship of a satirical poem with severe personal statements about a mill owner resulted in Wilson's arrest. His work was said to be inflammatory and libelous; he was often in trouble with the law. Because he devoted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conspecific
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and soc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bay-breasted Warbler
The bay-breasted warbler (''Setophaga castanea'') is a small species of songbird in the New World warbler family, Parulidae. It is one of thirty-four species in the diverse genus ''Setophaga.'' Like all songbirds, or passerines, the species is classified in the order Passeriformes. Distribution Bay-breasted warblers breed in the boreal spruce-fir forests of eastern and central Canada, as well as the extreme northern United States. The species winters in the wet lowland forests of northeastern South America, the Caribbean, and southern Central America, and may be seen during spring and fall migration across the eastern half of the United States in a variety of vegetative communities. Many individuals cross the Gulf of Mexico on their long-distance migration, although some travel north and south along the Mexican shore. Diet and behavior In the breeding season, bay-breasted warblers feed primarily on insects and spiders, especially the spruce budworm (''Choristoneura fumiferana'') ...

Wilson's Warbler
Wilson's warbler (''Cardellina pusilla'') is a small New World warbler. It is greenish above and yellow below, with rounded wings and a long, slim tail. The male has a black crown patch; depending on the subspecies, that mark is reduced or absent in the female. It breeds across Canada and south through the western United States, and winters from Mexico south through much of Central America. It is a very rare vagrant to western Europe. Taxonomy Wilson's warbler was formally described in 1811 by the ornithologist Alexander Wilson under the binomial name ''Muscicapa pusilla''. The type locality is southern New Jersey. The species was moved to the genus '' Wilsonia'' by the naturalist and ornithologist Charles Lucien Bonaparte in 1838. Zoologist Thomas Nuttall moved it to ''Sylvania'' in 1840, and by 1845, many authors included it in ''Myiodioctes.'' In 1899, the American Ornithological Union returned the species to ''Wilsonia.'' The species is currently assigned to the genus ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chestnut-sided Warbler
The chestnut-sided warbler (''Setophaga pensylvanica'') is a New World warbler. They breed in eastern North America and in southern Canada westwards to the Canadian Prairies. They also breed in the Great Lakes region and in the eastern United States. Etymology The genus name ''Setophaga'' is from Ancient Greek ''ses'', "moth", and ', "eating", and the specific ''pennsylvanicus'' means "Pennsylvania". Migration range These birds are migratory, wintering in Central America south to northern Colombia, with a confirmed sighting from as far south as Ecuador; they are also very rare vagrants to western Europe. They arrive in their breeding range in May and depart by mid-September. Description This species is a moderately-sized New World warbler. Despite having very different plumage, it is thought to be closely related to the widespread yellow warbler. In total, this species measures from in length and spans across the wings.

Blackpoll Warbler
The blackpoll warbler (''Setophaga striata'') is a New World warbler. Breeding males are mostly black and white. They have a prominent black cap, white cheeks and white wing bars. The blackpoll breeds in forests of northern North America, from Alaska throughout most of Canada, to the mountains of New York and New England. They are a common migrant through much of North America. In fall, they fly south to the Greater Antilles and the northeastern coasts of South America in a non-stop long-distance migration over open water, averaging 2500 km, one of the longest distance non-stop overwater flights ever recorded for a migratory songbird. Rare vagrants to western Europe, they are one of the more frequent transatlantic passerine wanderers. Etymology The genus name ''Setophaga'' is from Ancient Greek ''ses'', "moth", and ', "eating", and the specific ''striata'' means "striped". Description The blackpoll warbler is a fairly small bird which attains the weight of a ball poin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blackburnian Warbler
The Blackburnian warbler (''Setophaga fusca'') is a small New World warbler. They breed in eastern North America, from southern Canada, westwards to the southern Canadian Prairies, the Great Lakes region and New England, to North Carolina. Blackburnian warblers are migratory, wintering in southern Central America and in South America, and are very rare vagrants to western Europe. Etymology The genus name ''Setophaga'' is from Ancient Greek ''ses'', "moth", and ', "eating", and the specific ''fusca'' is Latin for brown. These birds were named after Anna Blackburne, an English botanist. Description Blackburnian warblers are small passerines and average-sized wood-warblers. They measure around long, with a wingspan, and weigh . The average mass of an adult bird is , although is slightly higher in fall due to fat reserves, averaging .

John Latham (ornithologist)
John Latham (27 June 1740 – 4 February 1837) was an English physician, naturalist and author. His main works were ''A General Synopsis of Birds'' (1781–1801) and ''General History of Birds'' (1821–1828). He was able to examine specimens of Australian birds which reached England in the last twenty years of the 18th century, and was responsible for providing English names for many of them. He named some of Australia's most famous birds, including the emu, sulphur-crested cockatoo, wedge-tailed eagle, superb lyrebird, Australian magpie, magpie-lark and pheasant coucal. He was also the first to describe the hyacinth macaw. Latham has been called the "grandfather" of Australian ornithology. Biography John Latham was born on 27 June 1740 at Eltham in northwest Kent. He was the eldest son of John Latham (died 1788), a surgeon, and his mother, who was a descendant of the Sothebys, in Yorkshire. He was educated at Merchant Taylors' School and then studied anatomy under Wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Emendation (zoology)
In zoological nomenclature, emendations are alterations made to the spelling of taxon names. In bacteriological nomenclature, emendations are made to the circumscription of a taxon. In zoology The change must be consciously made along with justification for altering the spelling originally used by the taxon author while describing the species. Any other spelling changes are considered to be unjustified. Valid emendations include changes made to correct: * typographical errors in the original work describing the species; * errors in transliteration from non-Latin scripts; * names that included diacritics or hyphens; * endings of species to match the gender of the generic name, particularly when the combination has been changed. The binomial authority In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of ...

AOS Checklist Of North American Birds
The ''AOS Checklist of North American Birds'' is a checklist of the bird species found in North and Middle America which is now maintained by the American Ornithological Society (AOS). The checklist was originally published by the AOS's predecessor, the American Ornithologists' Union (AOU). The Union merged with the Cooper Ornithological Society in 2016 to form the American Ornithological Society. The checklist was first published in 1886; the seventh edition of the checklist was published in 1998 and is now updated every year by an open-access article published in the ''Ibis''. Seven editions and 54 supplements (minor updates) have been published in the last 127 years. According to Joel Asaph Allen, the Codes of Nomenclature set out in the first edition of the Checklist "later became the basis of the International Code of Zoological Nomenclature, framed on essentially the same lines and departing from it in no essential respect, except in point of brevity, through omission of ade ...
