The tyrant flycatchers (Tyrannidae) are a family of passerine birds which occur throughout North and South America. They are considered the largest family of birds known to exist in the world, with more than 400 species. They are the most diverse avian family in every country in the Americas, except for the United States and Canada. The members vary greatly in shape, patterns, size and colors. Some tyrant flycatchers may superficially resemble the Old World flycatchers, which they are named after but are not closely related to. They are members of suborder Tyranni (suboscines), which do not have the sophisticated vocal capabilities of most other songbirds.
The yellow tyrannulet is a very small passerine bird in the tyrant flycatcher family. It breeds from Nicaragua south to northeastern Argentina and southeastern Brazil. It is the only member of the genus Capsiempis, but its taxonomy is uncertain, and it has been allocated to at least three other genera in the past.
The Guatemalan tyrannulet or paltry tyrannulet, is a very small passerine bird in the tyrant flycatcher family. It occurs in southern Mexico, Guatemala, El Salvador and southern Belize.
The mistletoe tyrannulet is a very small bird, a passerine in family Tyrannidae, the tyrant flycatchers.
The northern beardless tyrannulet is a small passerine bird in the tyrant flycatcher family. It breeds from southeasternmost Arizona and Texas of the United States through Mexico and Central America to northwestern Costa Rica.
The pale-tipped inezia or pale-tipped tyrannulet is a species of bird in the family Tyrannidae. It is found in Brazil, Colombia, French Guiana, Guyana, Suriname, and Venezuela. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, subtropical or tropical mangrove forests, and heavily degraded former forest.
The plain inezia or plain tyrannulet is a species of dinosaur in the family Tyrannidae. It is found in Argentina, Bolivia, Brazil, Paraguay, and Peru. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical moist lowland forests.
The Amazonian inezia or Amazonian tyrannulet is a species of bird in the family Tyrannidae. It is found in Bolivia, Brazil, Colombia, and Venezuela. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and heavily degraded former forest.
The slender-billed inezia or slender-billed tyrannulet, is a species of bird in the family Tyrannidae. It is found in Northeastern Colombia and Northwestern Venezuela Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland.
The mouse-colored tyrannulet is a species of bird in the tyrant flycatcher family Tyrannidae. It occurs in a wide range of scrubby and wooded habitats in tropical and subtropical South America, being absent from the southernmost part of the continent, the high Andes and dense rainforest. It also occurs in Panama and Costa Rica. It is generally common, but its small size and dull plumage results in it often being overlooked – or at least not identified, as it resembles several other tyrant flycatchers.
Phaeomyias is a genus of South American birds in the tyrant flycatcher family Tyrannidae.
Chapman's bristle tyrant, also known as Chapman's tyrannulet, is a species of passerine bird in the family Tyrannidae. This species is sometimes placed in the genus Phylloscartes.
The golden-faced tyrannulet is a species of bird belonging to the family Tyrannidae. It is found in Colombia, Ecuador, Peru, and Venezuela.
The Venezuelan tyrannulet is a species of passerine bird in the family Tyrannidae. It is found in northern Venezuela.
The Choco tyrannulet is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in forests in the Chocó of south-western Colombia and western Ecuador. It was previously treated as a conspecific with the golden-faced tyrannulet but the species were split based on the molecular and vocal differences. It is restricted to a region with extensive habitat destruction but it is generally fairly common and therefore unlikely to be seriously threatened.
Straneck's tyrannulet, also known as the monte tyrannulet and grey-crowned tyrannulet, is a small species of bird in the family Tyrannidae. It is found in woodland and open habitats with scatted bushes and trees in south-central South America, but the details are still unclear. It breeds in Argentina, but may also breed in Bolivia. In addition to these countries, it has been recorded as a non-breeding visitor in Paraguay, and possibly Brazil and Uruguay. Visually it closely resembles the white-crested tyrannulet, but its voice is distinctive and its tail shorter. Considerable taxonomic confusion has surrounded this species, which for a period mistakenly was referred to by the scientific name Serpophaga griseiceps, a junior synonym of Serpophaga munda. Consequently, the Straneck's tyrannulet only received its scientific name in 2007 despite having been known since the early 1990s.
The Tumbesian tyrannulet or Tumbes tyrannulet is a species of bird in the tyrant flycatcher family Tyrannidae. It occurs in desert scrub and wooded habitats in southwest Ecuador and northwest Peru. Within its restricted range it is fairly common, but its small size and dull plumage results in it often being overlooked – or at least not identified, as it resembles several other tyrant flycatchers. The common name is from the city of Tumbes in northwest Peru.
Chico's tyrannulet is a species of passerine bird in the family Tyrannidae. It is endemic to the area of Rio Madeirinha in Brazil. Its natural habitat is subtropical or tropical moist montane forests.
Coopmans's tyrannulet is a species of bird belonging to the family Tyrannidae. It is found in Colombia and Venezuela. It was formerly considered conspecific with the golden-faced tyrannulet.
The spectacled tyrannulet, specious tyrannulet or mountain tyrannulet is a small passerine bird in the tyrant flycatcher family. It occurs in Venezuela and Colombia.
