Straight-billed Hermit

Phaethornis bourcieri

The straight-billed hermit (Phaethornis bourcieri) is a species of bird in the family Trochilidae, the hummingbirds.

It is found in the Guyanas of Guyana, Suriname, and French Guiana; also the northern Amazon basin of Brazil, and Amazonian Colombia, Ecuador, and Peru; it is in eastern Venezuela and the Orinoco River Basin. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.

Two subspecies are currently recognised: P. b. bourcieri and P. b. major. However, recent molecular analysis has shown that P. b. major is more closely related to Phaethornis philippii and Phaethornis koepckeae than populations grouped under the bourcieri nominate, suggesting it should be treated as a separate species.
