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.
All the oropendolas are large birds with pointed bills, and long tails which are always at least partially bright yellow. Males are usually larger than females.
The plumage is typically chestnut, dark brown or black, although the Green oropendola and olive oropendola have, as their names imply, an olive coloration to the head, breast and upper back. The legs are dark, but the bill is usually a strikingly contrasting feature, either pale yellow, or red-tipped with a green or black base. In several species there is also a blue or pink bare cheek patch.
Oropendolas are birds associated with forests or, for a few species, more open woodland. They are colonial breeders, with several long woven basket nests in a tree, each hanging from the end of a branch.
These gregarious birds eat large insects and fruit. They are very vocal, producing a wide range of songs and calls, sometimes including mimicry.
The following species are recognised in the genus Psarocolius:
Four species of oropendola were formerly classified within the genus Gymnostinops; alternatively, the crested oropendola (and possibly others) would have also been placed here (Price & Lanyon 2002):
Price & Lanyon (2002) used mtDNA cytochrome b and NADH dehydrogenase subunit 2 sequence data to research oropendola phylogeny. As can be observed from morphology, the band-tailed (Ocyalus latirostris) and the casqued oropendolas (Psarocolius oseryi) are the most distinct species. Genetically, they appear to be more closely related to the caciques, and both species would be classified in the genus Ocyalus. Furthermore, the casqued oropendola could be separated into Clypicterus, forming what would then become a monotypic genus (like Ocyalus).
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 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.
The crested oropendola, also known as the Suriname crested oropendola or the cornbird, is a New World tropical icterid bird. It is a resident breeder in lowland South America east of the Andes, from Panama and Colombia south to northern Argentina, as well as on Trinidad and Tobago. If the genus Gymnostinax for the Montezuma oropendola and its closest relatives were considered valid, this species would probably belong in that genus.
The moriche oriole is a passerine bird in the New World family Icteridae. It is unrelated to Old World orioles. It is a breeding resident in the tropics of eastern South America. This bird is noted for its close association with the palm Mauritia flexuosa.
The yellow-rumped cacique is a passerine bird in the New World family Icteridae. It breeds in much of northern South America from Panama and Trinidad south to Peru, Bolivia and central Brazil. However, they have been sighted as far north as Nayarit state in Mexico.
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 caciques are passerine birds in the New World blackbird family which are resident breeders in tropical South America north to Mexico. All of the group are in currently placed in the genus Cacicus, except the aberrant yellow-billed cacique, and the Mexican cacique which constitute respective monotypic genera. Judging from mitochondrial DNA cytochrome b and NADH dehydrogenase subunit 2 sequence, the aberrant oropendolas band-tailed oropendola and casqued oropendola, Psarocolius oseryi seem to be closer to the caciques.
The chestnut-headed oropendola is a New World tropical icterid bird. The scientific name of the species commemorates Johann Georg Wagler, who established Psarocolius, the oropendola genus.
The Montezuma oropendola is a New World tropical icterid bird. It is a resident breeder in the Caribbean coastal lowlands from southeastern Mexico to central Panama, but is absent from El Salvador and southern Guatemala. It also occurs on the Pacific slope of Nicaragua and Honduras and northwestern and southwestern Costa Rica. It is among the oropendola species sometimes separated in the genus Gymnostinops. The English and scientific names of this species commemorate the Aztec emperor Moctezuma II.
The scarlet-rumped cacique is a passerine bird species in the New World family Icteridae. It breeds from eastern Honduras to Panama and in the Pacific lowlands of South America from western Colombia south to Ecuador, and in the lower reaches of the northern Andes. There are several subspecies, some of which have been proposed for elevation to full species status.
The olive oropendola is the largest member of the icterid family and rivals the Amazonian umbrellabird as the largest passerine bird in South America. It is sometimes placed in the genus Gymnostinops instead of Psarocolius. As suggested by its name, it is found widely – but often in low densities – throughout humid lowland forests of the Amazon Basin, with the notable exception of most of the Guiana Shield. It is sometimes split into two species, the western olive oropendola and the eastern Pará oropendola, but the subspecies P. y. neivae is widely recognized as a hybrid swarm, and the vast majority of authorities consider them a single species.
The black-cowled oriole is a species of bird in the family Icteridae. It is common and widespread in the Caribbean lowlands and foothills from southern Mexico to western Panama. It lives primarily in humid or semihumid forest, as well as in clearings, along forest edges, in plantations, in semi-open areas with scattered trees and bushes, and in gardens. The adult male is black, with yellow on the belly, shoulder, rump, wing lining, and crissum. The female's plumage varies depending on location. In the south of its range, it is similar to that of the male. In the north, its crown and upperparts are olive-yellow, while its face, throat, upper breast, wings, and tail are black.
The dusky-green oropendola is a species of bird in the family Icteridae. It is found on the eastern slope of the Andes in Bolivia and Peru. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.
The Baudó oropendola is a species of bird in the family Icteridae. It is endemic to Colombia. Its natural habitat is subtropical or tropical moist lowland forests, which are threatened by destruction. As it is only known from a small number of locations, its conservation status has been assessed as "endangered" by the IUCN.
The black oropendola is a species of bird in the family Icteridae. It is found in Colombia and Panama. Its natural habitat is subtropical or tropical moist lowland forests.
The green oropendola is a species of bird in the family Icteridae. It is found in wooded habitats in the Amazon basin and Guianas of South America, and is generally common. Uniquely among the oropendolas, the green oropendola has a pale bill with an orange tip. Male oropendola weigh around 400 grams, while females are in the 200 gram range. This is a common species and the International Union for Conservation of Nature has rated its status as being of "least concern".
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.
Myiothlypis is a genus of New World warblers, best represented in Central and South America. This is one of only two warbler genera that are well represented in the latter continent. All of these species were formerly placed in the genus Basileuterus.
The genus Leistes are predominantly South American grassland birds called meadowlarks. The genus was previously lumped with the North American meadowlarks in the genus Sturnella.
