The Yellow-bellied Elaenia is a medium sized, widespread elaenia found from southeastern Mexico south to northeastern Argentina. Generally Yellow-bellied Elaenias are brownish olive above with two white wing bars, a pale gray breast, and pale yellow belly. Yellow-bellied Elaenia have a conspicuous bushy crest that often is raised when the bird calls, revealing a white coronal patch. These flycatchers inhabit a variety of woodland habitats as well as scrub and savanna, and feed on fruits and insects. Yellow-bellied Elaenias often are relatively conspicuous, perching in the open and vocalizing frequently.
