The Sibley-Monroe checklist was a landmark document in the study of birds. It drew on extensive DNA-DNA hybridisation studies to reassess the relationships between modern birds.
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, 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. As could be expected from a family this large, the members vary greatly in shape, patterns, size and colors. Some tyrant flycatchers 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 common tody-flycatcher or black-fronted tody-flycatcher is a very small passerine bird in the tyrant flycatcher family. It breeds from southern Mexico to northwestern Peru, eastern Bolivia and southern, eastern and northeast Brazil.
Hemitriccus is a genus of small South American birds in the family Tyrannidae. They are commonly known as tody-tyrants or bamboo tyrants, but the former name is also shared with several members of the genus Poecilotriccus. Several species from the genus Hemitriccus are very similar, and consequently best separated by their voice.
The white-cheeked tody-flycatcher is a species of bird in the family Tyrannidae. It was formerly placed in the genus Todirostrum, and known as the white-cheeked tody-tyrant.
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 black-and-white tody-flycatcher is a species of bird in the family Tyrannidae. It was formerly placed in the genus Todirostrum, and known as the black-and-white tody-tyrant. It is found in thickets, especially bamboo, in southern Colombia, eastern Ecuador, eastern Peru, and south-western Brazil.
The smoky-fronted tody-flycatcher is a species of bird in the family Tyrannidae, and one of twelve in the genus Poecilotriccus.
The rusty-fronted tody-flycatcher is a species of bird in the family Tyrannidae, and one of twelve in the genus Poecilotriccus.
The Lulu's tody-flycatcher or Johnson's tody-flycatcher is a species of bird in the family Tyrannidae. It was briefly known as Lulu's tody-tyrant, but following the death of Ned K. Johnson, one of the people responsible for the description of this species in 2001, the name was modified to Johnson's tody-tyrant by the SACC. Following the move of this species to the genus Poecilotriccus from Todirostrum, it was recommended modifying the name to tody-flycatcher. It is endemic to humid thickets, usually near bamboo, in the highlands of Amazonas and San Martín in northern Peru. It is threatened by habitat loss and is consequently considered endangered by BirdLife International and IUCN.
The ochre-faced tody-flycatcher is a species of bird in the family Tyrannidae.
The black-backed tody-flycatcher is a species of bird in the family Tyrannidae, and one of twelve in the genus Poecilotriccus.
The rufous-crowned tody-flycatcher is a species of bird in the family Tyrannidae, the tyrant flycatchers. It was formerly placed in the genus Todirostrum, and has been known as the rufous-crowned tody-tyrant. It is found in thickets and second growth in the Andes of Venezuela, Colombia, Ecuador and far northern Peru.
The buff-cheeked tody-flycatcher is a species of bird in the family Tyrannidae. It is endemic to Brazil.
The yellow-browed tody-flycatcher is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found mainly in the southern Amazon Basin of Brazil, also Amazonian Colombia, Ecuador, Peru, and Bolivia; the species is recorded in Venezuela. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical swamps, and heavily degraded former forest.
The painted tody-flycatcher is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in the Guianas of French Guiana, Guyana and Suriname; also eastern-southeastern Venezuela and the northeastern states of Brazil of the Amazon Basin.
The yellow-lored tody-flycatcher or grey-headed tody-flycatcher is a species of bird in the family Tyrannidae. It is endemic to Brazil, occurring from Southern Bahia southwards to Santa Catarina. Measures an average of 8.8 centimeters and weighs an average of 6.8 grams.
Poliocephalus and its counterparts poliocephala and poliocephalum are Greek words meaning 'grey-headed'. Poliocephalus is the name for a genus of grebes, while Poliocephala is the name for a genus of flies. The two words are often used as the second word of a binomial name.
