Molothrus
Cowbirds are birds belonging to the genus ''Molothrus'' in the family Icteridae. They are of New World origin, but some species not native to North America are invasive there, and are obligate brood parasites, laying their eggs in the nests of other species. The genus was introduced by English naturalist William Swainson in 1832 with the brown-headed cowbird (''Molothrus ater'') as the type species. The genus name combines the Ancient Greek , meaning "struggle" or "battle", with , meaning "to sire" or "to impregnate". The English name "cowbird", first recorded in 1839, refers to this species often being seen near cattle. Species The genus contains six species: One extinct species, '' Molothrus resinosus'', is known from fossil remains recovered from the Talara Tar Seeps of northwestern Peru, and likely went extinct during the late Quaternary. It may have been a close associate of Pleistocene megafauna communities, and may have gone extinct following their collapse ...

Bronzed Cowbird
The bronzed cowbird (''Molothrus aeneus''), once known as the red-eyed cowbird, is a small icterid. They breed from the U.S. states of California, Arizona, New Mexico, Texas, and Louisiana south through Central America to Panama. They tend to be found in farmland, brush, and feedlots. Outside the breeding season, they are found in very open habitats, and roost in thick woods. These birds forage in open areas, often near cattle in pastures. Their diet mostly consists of seeds and insects, along with snails during breeding season for a calcium source. There are three subspecies: * ''M. a. loyei'' Parkes & Blake, 1965 is found in the southwestern United States and northwestern Mexico. * ''M. a. assimilis'' (Nelson, 1900) is found in southwestern Mexico. * ''M. a. aeneus'' ( Wagler, 1829), the nominate subspecies, is found in South Texas and from eastern Mexico to central Panama The bronze-brown cowbird, which is restricted to the Caribbean coast of Colombia, was formerly consider ...

Molothrus Bonariensis
The shiny cowbird (''Molothrus bonariensis'') is a passerine bird in the New World family Icteridae. It breeds in most of South America except for dense forests and areas of high altitude such as mountains. Since 1900 the shiny cowbird's range has shifted northward, and it was recorded in the Caribbean islands as well as the United States, where it is found breeding in southern Florida. It is a bird associated with open habitats, including disturbed land from agriculture and deforestation. Adults are sexually dimorphic. Males are all black with a purple-blue iridescence. The female is smaller, with dull brown plumage that is sometimes paler on the underparts. Females of the species can be distinguished from the female brown-headed cowbird by their longer, finer bills and flatter heads. The shiny cowbird's diet consists mainly of insects, other arthropods and seeds, and they have been recorded foraging for grains in cattle troughs. Like most other cowbirds, it is an obligate brood ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Screaming Cowbird
The screaming cowbird (''Molothrus rufoaxillaris'') is an obligate brood parasite belonging to the family Icteridae and is found in South America. It is also known commonly as the short billed cowbird.Fraga, R. M. (2011). Family Icteridae (New World Blackbirds). In Handbook of the Birds of the World, vol 16: Tanagers to New World Blackbirds (J. del Hoyo,. A. Elliot, and D. A. Christie, Editors). Lynx Edicions, Barcelona, Spain. pp. 684-807 Description The screaming cowbird has mildly iridescent black plumage; the lesser under-wing coverts are rufous. The female is slightly duller in colour than the male. The legs are black and the iris is reddish brown. Adult body length is 18–21 cm and mean adult weight is 58 g for males and 48 g for females.Davies, N. B. (2000). Cuckoos, Cowbirds and Other Cheats. Academic Press, London The call of the screaming cowbird was first described as "impetuous screaming notes"; however, a more useful description for field identifica ...

Icteridae
Icterids () or New World blackbirds make up a family, the Icteridae (), of small to medium-sized, often colorful, New World passerine birds. The family contains 108 species and is divided into 30 genera. Most species have black as a predominant plumage color, often enlivened by yellow, orange, or red. The species in the family vary widely in size, shape, behavior, and coloration. Etymology The name, meaning "jaundiced ones" (from the prominent yellow feathers of many species) comes from the - ''íkteros'' via the . Relationship to other species This group includes the New World blackbirds, New World orioles, the bobolink, meadowlarks, Quiscalus, grackles, cowbirds, oropendolas, and cacique (bird), caciques. Despite the similar names, the first groups are only distantly related to the Old World common blackbird (a thrush (bird), thrush) or to the Old World orioles. The Icteridae are not to be confused with the Icteriidae, a family created in 2017 and consisting of one specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molothrus Oryzivorus
The giant cowbird (''Molothrus oryzivorus'') is a large passerine bird in the New World family Icteridae. It breeds from southern Mexico south to northern Argentina, and on Trinidad and Tobago. It may have relatively recently colonised the latter island. It is a brood parasite and lays its eggs in the nests of other birds. Taxonomy The giant cowbird was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the orioles in the genus ''Oriolus'' and coined the binomial name ''Oriolus oryzivorus''. Gmelin based his account on the "rice bird" from Cayenne that had been described in 1782 by the English ornithologist John Latham in his multi-volume work ''A General Synopsis of Birds''. The specific epithet is from Latin ''oryza'' meaning "rice" and ''-vorus'' meaning "eating". The giant cowbird is now one of six cowbirds placed in the genus ''Molothrus'' that was introduc ...

Brown-headed Cowbird
The brown-headed cowbird (''Molothrus ater'') is a small, obligate brood parasitic icterid native to temperate and subtropical North America. It is a permanent resident in the southern parts of its range; northern birds migrate to the southern United States and Mexico in winter, returning to their summer habitat around March or April. Taxonomy The brown-headed cowbird was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1775 in his '' Histoire Naturelle des Oiseaux'' from a specimen collected in the Carolinas. The bird was also illustrated in a hand-colored plate engraved by François-Nicolas Martinet in the ''Planches Enluminées D'Histoire Naturelle'', which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name, but in 1783, Dutch naturalist Pieter Boddaert coined the binomial name ''Oriolus ater'' in his catalogue of the ''Planches Enlumin ...

Molothrus Armenti
The bronze-brown cowbird (''Molothrus armenti'') is a species of bird in the family Icteridae. It was long thought to be an isolated population of bronzed cowbird. Because it is found only in a narrow coastal band in northwestern Colombia, it is considered near-threatened by the International Union for Conservation of Nature The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the stat .... References {{Taxonbar, from=Q12263764 Birds described in 1829 ...
