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 southern beardless tyrannulet is a small passerine bird in the tyrant flycatcher family. It breeds from Costa Rica through South America south to Paraguay, Bolivia, and Argentina.
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 southern 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 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.
The rough-legged tyrannulet is a species of bird in the family Tyrannidae. It is found in Argentina, Bolivia, Brazil, and Paraguay. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.
The restinga tyrannulet is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is endemic to Brazil, on the south Atlantic coast centered on the state of Paraná in a 150 km wide coastal strip. Its natural habitats are subtropical or tropical dry shrubland and subtropical or tropical moist shrubland. It is threatened by habitat loss.
The sooty tyrannulet is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is small, usually weighing 9 grams with a length of 12 centimeters, and has gray or brownish-grey feathers with black tail feathers. It is found in Argentina, Brazil, and Uruguay; also southern Paraguay. A small extension of its range is in southeastern Bolivia.
Zimmerius is a genus of Neotropical birds in the family Tyrannidae.
The golden-faced tyrannulet is a species of bird belonging to the family Tyrannidae. It is found in Colombia, Ecuador, Peru, and Venezuela.
The slender-footed tyrannulet is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in humid forests of the west Amazon Basin in Venezuela, Colombia, Ecuador, Peru, Bolivia and Brazil. Until recently, it included the Guianan tyrannulet as a subspecies.
The Venezuelan tyrannulet is a species of passerine bird in the family Tyrannidae. It is found in northern Venezuela.
The Mishana tyrannulet is a species of bird in the family Tyrannidae. It is endemic to two geographically separated regions in northeastern Peru. It is speculated that the two populations might represent separate species entirely.
The Peruvian tyrannulet is a species of bird in the family Tyrannidae. As traditionally defined, it is endemic to Peru, but recent genetic evidence suggests it should include the taxon flavidifrons as a subspecies, in which case the range of the Peruvian tyrannulet extends into far southern Ecuador. Alternatively, flavidifrons is sometimes considered a separate species, the Loja tyrannulet, but it is not closely related to the golden-faced tyrannulet as previously believed.
The Yungas tyrannulet is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is, as suggested by its common name, restricted to humid and semi-humid forest in the Yungas of north-western Bolivia and far south-eastern Peru. Although discovered in the early 1990s, it was only formally described in 2008.
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.
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.
The spectacled tyrannulet, also known as specious tyrannulet or mountain tyrannulet, is a small passerine bird in the tyrant flycatcher family. It occurs in Venezuela and Colombia.
