The brown-headed cowbird 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.
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 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.
The shiny cowbird 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.

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 crested gallito is a species of suboscine passerine bird in the tapaculo family Rhinocryptidae. It is the only species placed in the genus Rhinocrypta. It is found in Argentina, Bolivia, and Paraguay.
The white-rumped swallow is a species of bird in the family Hirundinidae. First described and given its binomial name by French ornithologist Louis Pierre Vieillot in 1817, it was for many years considered a subspecies of the Chilean swallow. The species is monotypic with no known population variations. It has a white supraloral streak, or streak above its lores, which can be used to differentiate it from the Chilean swallow. The lores, ear coverts, tail, and wings are black, with white tips on the inner secondaries, tertials, and greater coverts of the wings. The rest of the upperparts are a glossy blue. Its underparts and underwing-coverts are white, in addition to the rump, as the name suggests. The sexes are similar, and the juvenile is duller and browner with a dusky breast.
The broad-tailed paradise whydah is a species of bird in the family Viduidae. It is found woodland and acacia savanna habitat in Sub-Saharan Africa from Angola to Uganda, Tanzania and Mozambique. A brood parasite, it has a wide range and the International Union for Conservation of Nature has assessed it as being of least concern.
The pale baywing, formerly known as the pale cowbird, is a species of bird in the family Icteridae. It is currently placed in the genus Agelaioides, but has traditionally been placed in the genus Molothrus. It was formerly considered conspecific with the greyish baywing, with the combined species then known as bay-winged cowbird.
The baywings are two species of birds in the genus Agelaioides, which were described in the early 19th century. These species are found in Brazil and in the case of A. badius, also Argentina, Bolivia, Uruguay, and Paraguay. They were formerly in included in genus Molothrus with cowbirds.
