The lesser wagtail-tyrant (Stigmatura napensis) is a small South American species of bird in the family Tyrannidae. It occurs in two distinct populations: One found in wooded and shrubby habitats along major Amazonian rivers in Brazil, Peru, Ecuador and Colombia, and a second found in the comparable far drier northeastern Brazil. The latter is sometimes considered a separate species, the Bahian wagtail-tyrant (S. bahiae), named after the state Bahia, where the majority of its less ↑

The short-tailed pygmy tyrant (Myiornis ecaudatus) is a small species of tyrant-flycatcher. The species is one of the smallest birds on Earth and the smallest passerine. Among both the family and the order, only the closely related black-capped pygmy tyrant approaches similarly diminutive sizes. The pygmy tyrant is widespread throughout most of the Amazon in northern and central South America. less ↑

The willow flycatcher (Empidonax traillii) is a small insect-eating, neotropical migrant bird of the tyrant flycatcher family. There are four subspecies of the willow flycatcher currently recognized, all of which breed in North America (including three subspecies that breed in California). Empidonax flycatchers are almost impossible to tell apart in the field so biologists use their songs to distinguish between them. The binomial commemorates the Scottish zoologist Thomas Ste less ↑

The scarlet flycatcher or austral vermilion flycatcher (Pyrocephalus rubinus) is a species of flycatcher, closely related to the vermilion flycatcher. It is found in southeastern Bolivia and Brazil, Paraguay to Argentina and Uruguay. It is recognized as a species by some taxonomic authorities, including the International Ornithologists' Union. Others still consider it to be a subspecies of the vermilion flycatcher. less ↑

The cattle tyrant (Machetornis rixosa) is a species of bird in the tyrant-flycatcher family Tyrannidae. It is the only member of the genus Machetornis. The relationships of this species and genus to other genera in the tyrant flycatchers are uncertain. It resembles Tyrannus flycatchers, but this may be the result of convergence. Three subspecies are recognised, the nominate race, M. r. flavigularis and M. r. obscurodorsalis, although the latter two less ↑

This bird breeds from southern Arizona and the lower Rio Grande Valley of Texas in the United States through Central America, South America as far as south as central Argentina and western Peru, and on Trinidad and Tobago. Birds from the northernmost and southern breeding areas migrate to warmer parts of the range after breeding. less ↑

Cotingas are birds of forests or forest edges, which mostly eat fruit or insects and fruit. Comparatively little is known about this diverse group, although all have broad bills with hooked tips, rounded wings, and strong legs. They may be the most diverse passerine family in body size, ranging from the 8 centimetres (3.15 in) kinglet calyptura to the... less ↑

The distribution is disjunct, with one population in the western Amazon Basin and adjacent east Andean foothills in south-eastern Colombia, eastern Ecuador and eastern Peru, and another population in the humid Chocó in eastern Panama, western Colombia and north-western Ecuador. It has been suggested that the latter population may be a separate s less ↑

It is found upriver in the western Amazon Basin and the neighboring countries of northern Peru, eastern Ecuador and Colombia, and southern and western portions of Venezuela. In Venezuela it occurs upriver in the Orinoco River basin, but not the final 1300 km; its range in Venezuela continues around the Andes cordillera to the northwestern coast. In northwest Brazil, the species ranges from... less ↑

The striped manakin (Machaeropterus regulus) is a small South American species of bird in the Pipridae family. Its distribution is highly disjunct: The nominate subspecies is found in Atlantic Forest in eastern Brazil, while the striolatus group is found in forests in western Brazil, northeastern Peru, eastern Ecuador, Colombia, and western and southern Venezuela. Males of the former group have redder underparts than males of the latter, and the two are sometimes treated as s less ↑

The white-crowned manakin (Dixiphia pipra) is a tiny passerine bird in the manakin family. It is a resident breeder in the tropical New World from Costa Rica to northeastern Peru and eastern Brazil.

Females and juveniles are olive-green with pink legs. At breeding time, males are involved in a cooperative lekking behaviour durin less ↑

Tityridae is family of suboscine passerine birds found in forest and woodland in the Neotropics. The 45 species in this family were formerly spread over the families Tyrannidae, Pipridae and Cotingidae (see Taxonomy). As yet, no widely accepted common name exists for the family, although tityras and allies and tityras, mourners and allies have been used. They are small to medium-sized birds. Under current classification, the family ranges in size from the buff-throated less ↑

The black-tailed tityra (Tityra cayana) is a medium-sized passerine bird of tropical South America. The tityras have been placed in the cotinga or the tyrant flycatcher families (Cotingidae and Tyrannidae) by various authors. But the weight of evidence strongly suggest they and their closest relatives are better separated as Tityridae; the AOU for example advocates this separation. less ↑

The black-crowned tityra (Tityra inquisitor) is a medium-sized passerine bird. It has traditionally been placed in the cotinga or the tyrant flycatcher family, but evidence strongly suggest it is better placed in Tityridae, where now placed by SACC. It is found in Argentina, Belize, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, French Guiana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Suriname, Trinidad and Tobago, and Venezuela. Its natural habitats a less ↑
