Acrochordopus is a genus of small passerine birds in the tyrant flycatcher family Tyrannidae. The genus contains two species.
The genus Acrochordopus was introduced in 1905 by the ornithologists Hans von Berlepsch and Carl Eduard Hellmayr. They designated the type species as Phyllomyias subviridis Pelzeln which is a junior synonym of Phyllomyias burnmeisteri Cabanis and Heine, the rough-legged tyrannulet. [1] [2] The genus name combines Ancient Greek ακροχορδων/akrokhordōn, ακροχορδονος/akrokhordonos meaning "wart" with πους/pous, ποδος/podos meaning "foot". [3]
The genus contains two species: [4]
The two species are very similar in appearance and were formerly considered as conspecific. They were split based on differences in vocalization and genetics. [4] [5] These species were formerly placed in the genus Phyllomyias . A large molecular phylogenetic study by Michael Harvey and collaborators published in 2020 found that the genus Phyllomyias was paraphyletic. As part of the reorganization to create monotypic genera, the genus Acrochordopus was resurrected to contain the above two species. [4] [6]
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, 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.
Lophotriccus is a genus of South American birds in the tyrant flycatcher family Tyrannidae.
Neoxolmis is a genus of South American birds in the tyrant flycatcher family Tyrannidae.
The rough-legged tyrannulet is a species of bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Bolivia, Brazil, Paraguay, and Uruguay.
Phyllomyias is a genus of small birds in the tyrant-flycatcher family Tyrannidae. They are found in wooded habitats of Central and South America. Some species are among the commonest birds in their range, while other are rare and threatened. They have a short, stubby bill, are greenish above, yellowish or whitish below, and all except the sooty-headed tyrannulet have pale wing-bars or edging. They feed on small arthropods and fruits. Most species regularly take part in mixed species flocks.
The ashy-headed tyrannulet is a species of bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers. It is found in Colombia, Ecuador, Peru, and Venezuela.
The black-capped tyrannulet is a small passerine bird in the tyrant flycatcher family Tyrannidae. It is found in Colombia, Ecuador, Peru, and Venezuela. Its natural habitat is subtropical or tropical moist montane forests.
Sclater's tyrannulet is a species of bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Bolivia, and Peru.
Urich's tyrannulet is an Endangered species of bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers. It is endemic to Venezuela.
The tawny-rumped tyrannulet is a species of bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers. It is found in Bolivia, Colombia, Ecuador, Peru, Venezuela, and possibly Argentina.
The greenish tyrannulet is a species of bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Brazil, Paraguay, and Uruguay.
The Serra do Mar bristle tyrant is a small species of bird in the tyrant flycatcher family Tyrannidae. It was formerly placed in the genus Phylloscartes and known in English as the Serra do Mar tyrannulet. It is endemic to humid montane forest in the Serra do Mar in south-eastern Brazil. More likely confused with the short-tailed and pale-eyed hangnest tody-tyrant, its bright olive-green upperparts contrast strongly with the grey underparts. It is generally uncommon and threatened by habitat loss.
The São Paulo bristle tyrant is a species of bird in the tyrant flycatcher family Tyrannidae. It was formerly placed in the genus Phylloscartes and known in English as the São Paulo tyrannulet. It is found in the southern Atlantic Forest region of South America. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. It is threatened by habitat loss.
Poecilotriccus is a genus of small flycatchers in the family Tyrannidae. Except for the recently described Johnson's tody-flycatcher, all have, at one point or another, been included in the genus Todirostrum. Some species have been known as tody-tyrants instead of tody-flycatchers. Most species are found in South America, but a single species, the slate-headed tody-flycatcher, is also found in Central America. The black-chested tyrant may also belong in this genus, but most place it in the monotypic genus Taeniotriccus.
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.
