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 genus Empidonax is a group of small insect-eating passerine birds in the tyrant flycatcher family, the Tyrannidae. The genus name Empidonax is from Ancient Greek empis, "gnat", and anax, "master".
The shrike-tyrants are a genus, Agriornis, of birds in the tyrant flycatcher family Tyrannidae. The members of this genus are found in open habitats in western and southern South America, usually at high elevations. They are large and heavy billed by tyrant-flycatcher standards, and include the largest representative of the family, the great shrike-tyrant. These five species all have a dull brownish or greyish plumage. Despite their name any similarity with the shrikes is superficial. Many field guides note their greater resemblance to thrushes.
Alectrurus is a genus of South American birds in the tyrant flycatcher family Tyrannidae.
The ash-breasted tit-tyrant is a small bird of the Tyrannidae family, located in the High Andes of Peru and in Bolivia. This bird is commonly found at an elevation of 3700-4600 meters high. They are an endangered species, as the population is continuously decreasing due to various threats. They can be identified by their dark gray color, with two white bars on their wings and around the tail. The Ash-breasted Tit-Tyrant is uncommon but very local.
The tufted tit-tyrant is a species of bird in the tyrant flycatcher family Tyrannidae. This species is found in western South America; its range stretches from southern Colombia south along the Andes mountains to Tierra del Fuego. It prefers to live in upper montane forests and shrublands; however, it is a habitat generalist and can be found across a wide range of ecosystems. The tufted tit-tyrant has three subspecies, including the nominate subspecies Anairetes parulus parulus, A. p. aequatorialis, and A. p. patagonicus, and is very closely related to the Juan Fernández tit-tyrant. It is very small with a distinctive and conspicuous crest. The bird's head is black overall with white supraloral and postocular stripes. Its dull grayish-brown back contrasts with its white throat and breast that are covered with black streaks and pale, unmarked yellow underbelly. There are few noticeable differences in plumage between the subspecies. It is a vocal flycatcher with a broad repertoire of songs.
Casiornis is a genus of South American birds in the tyrant flycatcher family Tyrannidae.
Conopias is a genus of birds in the tyrant flycatcher family Tyrannidae.
Euscarthmus is a genus of South American birds in the tyrant flycatcher family Tyrannidae.
Mecocerculus is a genus of birds in the large tyrant flycatcher family Tyrannidae.
Myiopagis is a genus of bird in the family Tyrannidae, the tyrant flycatchers. These species are closely related to the genus Elaenia but are generally smaller.
Myiophobus is a genus of birds in the tyrant flycatcher family Tyrannidae.
Myiotheretes is a genus of South American birds in the tyrant flycatcher family Tyrannidae. These superficially thrush-like birds are large tyrants of the Andean highlands. The red-rumped bush tyrant is considered closely related.
Ornithion is a genus of birds in the large tyrant flycatcher family Tyrannidae.
Nesotriccus is a genus of Central and South American birds in the tyrant flycatcher family Tyrannidae.
Rhytipterna is a genus of bird in the tyrant flycatcher family Tyrannidae. They share the common name "mourner" with several species in the family Tityridae.
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.
Sublegatus is a genus of birds in the tyrant flycatcher family Tyrannidae.
Anairetes is a genus containing the tit-tyrants, a group of small, mainly Andean birds, in the tyrant flycatcher family Tyrannidae. The group briefly included the genus Uromyias, which had been recognized based on syringeal and plumage characters, including a flatter crest and a longer tail, but was included within Anairetes due to genetic analysis. Recent analyses suggested splitting into Uromyias again. Anairetes is believed to be most closely related to the genera Mecocerculus and Serpophaga; however, there is no definitive evidence supporting this claim.
Sirystes is a genus of birds in the tyrant flycatcher family, Tyrannidae. They used to be all considered conspecific. Vocal differences primarily separated the superspecies into four distinct taxa.
