see text Elaenia is a genus of passerine birds in the tyrant flycatcher family which occur in Mexico, the Caribbean, and Central and South America.

They are also known by the common name elaenia, which they share with the similar tyrant flycatchers of the genus Myiopagis.

Elaenia flycatchers are typically brownish, greyish or olive above, and off-white and/or pale yellow on the belly, with a white or pale yellowish eye-ring of variable strength and two or three wing bars.

The genus Elaenia was introduced by the Swedish zoologist Carl Jakob Sundevall in 1836.

[3] The name of the genus is from the Ancient Greek ελαινεος elaineos "of olive-oil" or "oleaginous".
