The red-winged blackbird is a passerine bird of the family Icteridae found in most of North America and much of Central America. It breeds from Alaska and Newfoundland south to Florida, the Gulf of Mexico, Mexico, and Guatemala, with isolated populations in western El Salvador, northwestern Honduras, and northwestern Costa Rica. It may winter as far north as Pennsylvania and British Columbia, but northern populations are generally migratory, moving south to Mexico and the Southern United States. Claims have been made that it is the most abundant living land bird in North America, as bird-counting censuses of wintering red-winged blackbirds sometimes show that loose flocks can number in excess of a million birds per flock and the full number of breeding pairs across North and Central America may exceed 250 million in peak years. It also ranks among the best-studied wild bird species in the world. The red-winged blackbird is sexually dimorphic; the male is all black with a red shoulder and yellow wing bar, while the female is a nondescript dark brown. Seeds and insects make up the bulk of the red-winged blackbird's diet.
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. The name, meaning "jaundiced ones" comes from the Ancient Greek ikteros via the Latin ictericus. This group includes the New World blackbirds, New World orioles, the bobolink, meadowlarks, grackles, cowbirds, oropendolas, and caciques.
The avian genus Quiscalus contains seven of the 11 species of grackles, gregarious passerine birds in the icterid family. They are native to North and South America.
The yellow-headed blackbird is a medium-sized blackbird with a yellow head.
Cowbirds are birds belonging to the genus Molothrus in the family Icteridae. They are of New World origin, and are obligate brood parasites, laying their eggs in the nests of other species.
The red-breasted meadowlark is a passerine bird in the New World family Icteridae. It was formerly named red-breasted blackbird but is not closely related to the red-winged blackbird group.
The genus Sturnella are North American grassland birds called meadowlarks. The genus was previously lumped with the South American meadowlarks now placed in the genus Leistes.
The giant cowbird 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.
Oropendolas are a genus of passerine birds, Psarocolius, in the New World blackbird family Icteridae. They were formerly split among two or three different genera and are found in Central and South America.
The tricolored blackbird is a passerine bird of the family Icteridae. Its range is limited to the coastal areas of the Pacific coast of North America, from Northern California in the U.S., to upper Baja California in Mexico.
Euphagus is a small genus of American blackbirds. It contains two extant species: Brewer's blackbird, Euphagus cyanocephalus, and rusty blackbird E. carolinus.
The yellow-shouldered blackbird, known in Puerto Rican Spanish as mariquita de Puerto Rico or capitán, is a species of blackbird endemic to Puerto Rico. It has black plumage with a prominent yellow patch on the wing. Adult males and females are of similar appearance. The species is predominantly insectivorous.
The red-shouldered blackbird is a species of bird in the family Icteridae. It is endemic to Cuba, but despite its limited range, the species is listed as Least Concern on the IUCN Red List.
The tawny-shouldered blackbird is a species of bird in the family Icteridae. It is found in Cuba and Hispaniola. It is a vagrant in the United States.
The Jamaican blackbird is a species of bird in the New World blackbird and oriole family Icteridae. It is the only species (monotypic) in the genus Nesopsar. The species has sometimes been included in the genus Agelaius, but molecular systematics have shown it not be closely related to any living New World blackbird or grackle. The species is endemic to Jamaica, where it is restricted to Cockpit Country, some central areas and the Blue and John Crow Mountains.
Chihuahuan meadowlark, also known as Lilian's meadowlark, is a bird in the family Icteridae. It is found in northern Mexico and the southwestern portion of the United States. It was formerly usually treated as a subspecies of the eastern meadowlark.
The saffron-cowled blackbird is a species of bird in the family Icteridae. It is the only species placed in the genus Xanthopsar. It has bright yellow underparts and black or dark brown upperparts. It is found in Argentina, Brazil, Paraguay, and in Uruguay at the Quebrada de los Cuervos. Its natural habitats are subtropical or tropical dry lowland grassland, subtropical or tropical seasonally wet or flooded lowland grassland, and pastureland. It is threatened by habitat loss.
Canebrake Ecological Reserve is a 6,700-acre (27 km2) nature reserve in the South Fork Valley of Kern County, 20 miles (32 km) east of Lake Isabella, California. It is located in the Southern Sierra Nevada region.
The convex-billed cowbird is an extinct species of bird in the family Icteridae, described in 1947 by Alden H. Miller. It is the only member of its genus, Pandanaris.
