Three-banded warbler

The three-banded warbler (Basileuterus trifasciatus) is a species of bird in the Parulidae family. It is found in Ecuador and Peru. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.

Basileuterus

Basileuterus is a genus of New World warblers, best represented in Central and South America. This is one of only two warbler genera that are well represented in the latter continent. Some species formerly considered in this genus are now placed in the genus Myiothlypis. It is likely that the ancestors of this genus colonised South America from the family’s heartland in northern Central America even before the two continents were linked, and subsequent speciation provided most of the resident warbler species of that region.

These are mainly robust warblers with a stout bill. The majority of species have olive or grey upperparts and yellow underparts. The head is often strikingly marked with a long broad supercilium, a coloured crown or crown stripes, and often other striking head markings.

Many species are not well-studied, but those for which the breeding habits are known all build a domed nest on a bank or on the ground, so this is presumably typical of the genus as a whole.

List of birds of Ecuador

This is a list of the bird species recorded in Ecuador including those of the Galápagos Islands. The avifauna of Ecuador has 1635 confirmed species, of which seven are endemic to the mainland and 30 are endemic to the Galápagos. Four have been introduced by humans, 64 are rare or vagrants, and two have been extirpated. An additional 49 species are hypothetical (see below).

Except as an entry is cited otherwise, the list of species is that of the South American Classification Committee (SACC) of the American Ornithological Society. The list's taxonomic treatment (designation and sequence of orders, families, and species) and nomenclature (common and scientific names) are also those of the SACC.The following tags have been used to highlight certain categories of occurrence.

(V) Vagrant - a species that rarely or accidentally occurs in Ecuador

(EG) Endemic - Galápagos - a species endemic to the Galápagos Islands

(EM) Endemic - mainland - a species endemic to mainland Ecuador

(I) Introduced - a species introduced to Ecuador as a consequence, direct or indirect, of human actions

(H) Hypothetical - a species recorded but with "no tangible evidence" according to the SACC

List of birds of Peru

This is a list of the bird species recorded in Peru. The avifauna of Peru has 1802 confirmed species, of which 106 are endemic, two have been introduced by humans, and 44 are rare or vagrants. An additional 54 species are hypothetical (see below).

New World warbler

The New World warblers or wood-warblers are a group of small, often colorful, passerine birds which make up the family Parulidae and are restricted to the New World. They are not closely related to Old World warblers or to Australian warblers. Most are arboreal, but some, like the ovenbird and the two waterthrushes, are primarily terrestrial. Most members of this family are insectivores.

It is likely that this group originated in northern Central America, where the greatest number of species and diversity between them is found. From there they spread north during the interglacial periods, mainly as migrants, returning to the ancestral region in winter. Two genera, Myioborus and Basileuterus, seem to have colonized South America early, perhaps before the two continents were linked, and together constitute most warbler species of that region.

The scientific name for the family, Parulidae, originates from the fact that Linnaeus in 1758 named the northern parula as a tit, Parus americanus, and, as taxonomy developed, the genus name was modified first to Parulus and then to Parula. The family name derives from the name for the genus.

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.
