Setophaga
''Setophaga'' is a genus of birds of the New World warbler family Parulidae. It contains at least 34 species. The ''Setophaga'' warblers are an example of adaptive radiation with the various species using different feeding techniques and often feeding in different parts of the same tree. Most ''Setophaga'' species are long-range migrants, wintering in or near the New World tropics and seasonally migrating to breed in North America. In contrast, two ''Setophaga'' species, the palm warbler and yellow-rumped warbler, have winter ranges that extend along the Atlantic coast of North America as far north as Nova Scotia. The males in breeding plumage are often highly colorful. Etymology The genus name ''Setophaga'' means ''moth eater'' in Ancient Greek; from : ''sēs'' (genitive σητός : ''sētós''), "moth", and : ''phágos'', "eating". Taxonomy The genus ''Setophaga'' was introduced by the English naturalist William Swainson in 1827. The type species was subsequently designat ...

New World Warbler
The New World warblers or wood-warblers are a group of small, often colorful, passerine birds that make up the family Parulidae and are restricted to the New World. The family contains 120 species. They are not closely related to Old World warblers or Australian warblers. Most are arboreal, but some, like the ovenbird and the two waterthrushes, are primarily terrestrial. Most members of this family are insectivores. This group likely originated in northern Central America, where the greatest number of species and diversity between them is found. From there, they spread north during the interglacial periods, mainly as migrants, returning to the ancestral region in winter. Two genera, '' Myioborus'' and '' Basileuterus'', seem to have colonized South America early, perhaps before the two continents were linked, and together constitute most warbler species of that region. The scientific name for the family, Parulidae, originates from the fact that Linnaeus in 1758 named the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Redstart
The American redstart (''Setophaga ruticilla'') is a New World warbler. It is unrelated to the Old World Common redstart, (common) redstart. Taxonomy The American redstart was described by Carl Linnaeus in 1758 in the 10th edition of Systema Naturae, 10th edition of his ''Systema Naturae'' under the Binomial nomenclature, binomial name ''Motacilla ruticilla''. The genus name ''Setophaga'' is from Ancient Greek σής : ''sēs'' (genitive σητός : sētós) "moth", and ' : phágos "eater". The specific ''ruticilla'' is Neo-Latin for "redstart" from Latin ''rutilus'', "red", and the diminutive ''-cilla''. In Ancient Greek the name was φοινίκουρος : ''phoiníkouros'' (from φοῖνιξ : ''phoĩnix-'' "red" and οὐρά : ''ourá'' "tail") "Redstart" refers to the male's red tail, "start" being an old word for tail. Description The American redstart is a smallish warbler. It measures in total length and has a wingspan of . Its length is boosted by a relat ...

American Yellow Warbler
The yellow warbler (''Setophaga petechia'') is a New World warbler species. Yellow warblers are the most widespread species in the diverse genus '' Setophaga'', breeding in almost the whole of North America, the Caribbean, as well as northern South America. Etymology The genus name ''Setophaga'' is from Ancient Greek ''ses'', "moth", and ', "eating", and the specific ''petechia'' is from Italian ''petecchia'', a small red spot on the skin. Description and taxonomy Other than in male breeding plumage and body size, all warbler subspecies are very similar. Winter, female and immature birds all have similarly greenish-yellow uppersides and are a duller yellow below. Young males soon acquire breast and, where appropriate, head coloration. Females are somewhat duller, most notably on the head. In all, the remiges and rectrices are blackish olive with yellow edges, sometimes appearing as an indistinct wing-band on the former. The eyes and the short thin beak are dark, while the feet ... [...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 South America, and are very rare vagrants to western Europe. Etymology The genus name ''Setophaga'' is from the Ancient Greek ''ses'', "moth", and ', "eating". The specific ''fusca'' is Latin for brown. The common name is for 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 . Among standard measurements, the wing chord is , the tail is , the bill is and the tarsus is . In summer, male Blackburnian warblers display dark gr ...

Adelaide's Warbler
Adelaide's warbler (''Setophaga adelaidae''), or reinita mariposera (in Puerto Rican Spanish) is a bird endemic to the archipelago of Puerto Rico belonging to the genus ''Setophaga'' of the family Parulidae (New World warblers). Taxonomy The ''S. adelaidae'' complex was originally considered a single species, with three populations occurring in Barbuda, Puerto Rico and St. Lucia. Each of these populations were regarded as a subspecies, ''S.a. subita'', ''S.a. adelaidae'' and ''S.a. delicata'' respectively. These subspecies were later elevated to species rank as the Barbuda warbler (''Setophaga subita''), the St. Lucia warbler (''Setophaga delicata'') and Adelaide's warbler. In 2011, the American Ornithologists' Union reclassified the Parulidae, which resulted in ''D. adelaidae'' being transferred to the genus ''Setophaga.'' The species is named after Maria Antoinette Adelaide Florentia del Carmen Swift Washburne (1829–1884), daughter of Robert Swift, the person who obtain ...

Allopatric Speciation
Allopatric speciation () – also referred to as geographic speciation, vicariant speciation, or its earlier name the dumbbell model – is a mode of speciation that occurs when biological populations become geographically isolated from each other to an extent that prevents or interferes with gene flow. Various geographic changes can arise such as the continental drift, movement of continents, and the formation of mountains, islands, bodies of water, or glaciers. Human activity such as agriculture or developments can also change the distribution of species populations. These factors can substantially alter a region's geography, resulting in the separation of a species population into isolated subpopulations. The vicariant populations then undergo Genetics, genetic changes as they become subjected to different Natural selection, selective pressures, experience genetic drift, and accumulate different mutations in the separated populations' gene pools. The barriers prevent t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...
