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.
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 mistletoe tyrannulet is a very small bird, a passerine in family Tyrannidae, the tyrant flycatchers.
The Amazonian Inezia or Amazonia Tyrannulet is a tiny tyrant-flycatcher bird that belongs to the Tyrannidae family found in riverine forests and scrub, including on islands, from southwest Venezuela and neighboring southeast Colombia south through the Amazonian region to northern Bolivia. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and heavily degraded former forest. Its prominent white supraloral and eye-ring, as well as its extremely "spotty" double wingbars, are what most easily set it apart. Olive-green to pale yellow makes up the majority of the rest of the feathers. With their tails held cocked, the species is frequently found in pairs, usually low to the ground. However, very little else about the biology and behavior of this tyrannulet has been documented to this point. The Amazonian Tyrannulet and the allopatric Pale-tipped Tyrannulet of northern South America were once thought to be conspecific, however vocalizations and, to a lesser extent, morphology clearly distinguish them from one another.
The cattle tyrant is a species of bird in the tyrant-flycatcher family Tyrannidae. In Brazil, it is called suiriri-cavaleiro. It is the only member of the genus Machetornis. The relationships of this species and genus to other genera in the tyrant flycatchers are uncertain. It resembles Tyrannus flycatchers, but this may be the result of convergence. Three subspecies are recognised, the nominate race, M. r. flavigularis and M. r. obscurodorsalis, although the latter two may not be distinct from M. r. flavigularis. The genus name was given to the species by George Robert Gray and is derived from the Ancient Greek makhētēs for fighter and ornis for bird, a reference to its pugnacious behaviour and habit of dispossessing other species of their nests. The specific name comes from the Latin rixosus meaning quarrelsome, again referring to the behaviour and temperament of the species.
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 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 wing-barred piprites is a species of bird in subfamily Pipritinae of family Tyrannidae, the tyrant flycatchers. It is found in every mainland South American country except Chile and Uruguay.
The grey-headed piprites is a species of bird in subfamily Pipritinae of family Tyrannidae, the tyrant flycatchers. It is found in Costa Rica, Guatemala, Honduras, Nicaragua, and Panama.
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.
