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.
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 white-fronted tyrannulet was formerly considered a subspecies.
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 sooty-headed tyrannulet is a species of bird in the family Tyrannidae. It is found in Brazil, Colombia, Ecuador, Guyana, Panama, Peru, and Venezuela.
The grey-capped tyrannulet is a species of bird in the family Tyrannidae. It is endemic to Brazil.
The black-capped tyrannulet is a species of bird in the family Tyrannidae. It is found in Colombia, Ecuador, Peru, and Venezuela. Its natural habitat is subtropical or tropical moist montane forests.
The plumbeous-crowned tyrannulet is a species of bird in the family Tyrannidae. It is found in the countries of Colombia, Ecuador, and Peru. Its natural habitat is subtropical or tropical moist montanes.
Reiser's tyrannulet is a species of bird in the family Tyrannidae. It is found in central Brazil and northern Paraguay. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical moist lowland forests.
Sclater's tyrannulet is a species of bird in the family Tyrannidae. It is found in Argentina, Bolivia, and Peru. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.
Urich's tyrannulet is a species of bird in the family Tyrannidae. It is endemic to Venezuela. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
The tawny-rumped tyrannulet is a species of bird in the family Tyrannidae. It is found in Argentina, Bolivia, Colombia, Ecuador, Peru, and Venezuela. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.
The greenish tyrannulet is a species of bird in the family Tyrannidae. It is found in Argentina, Brazil, and Paraguay. Its natural habitats are temperate forests, subtropical or tropical moist lowland forests, and subtropical or tropical moist montane forests.
The mottle-cheeked tyrannulet is a generally common, small species of bird in the family Tyrannidae. It occurs in two disjunct populations, one associated with montane Atlantic Forest in south-eastern Brazil, eastern Paraguay, north-eastern Argentina and Uruguay, and another found in forest growing on the east Andean slope in Peru, Bolivia and north-western Argentina. A very active bird usually seen with its tail held cocked.
The river tyrannulet is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Peru, Venezuela and Brazil; also river extensions into Ecuador, Colombia-(border) and Bolivia.
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.
The white-crested 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 Argentina, Bolivia, Brazil, Paraguay, and Uruguay. It is closely related to the white-bellied tyrannulet, but unlike that species the belly of the white-crested tyrannulet is yellow. The recently described Straneck's tyrannulet is extremely similar to the white-crested tyrannulet and was for a long time confused with that species; the two are generally best separated by voice.
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.
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 white-fronted tyrannulet is a species of bird in the family Tyrannidae. It is found in Colombia, Costa Rica, Ecuador, Panama, Peru, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.
