With a gray crown and yellow underparts, this warbler lives in grass and scrub from Mexico to western Panama, in lowlands and hills.
It is olive above with a gray crown, black lores, and a narrow, broken white eye-ring. The underside is yellow, brightest on the throat and undertail; the female is slightly duller.
Unlike the more marsh-oriented Common Yellowthroat, it often lives in rank weedy or brushy fields.
Its songs include a garbled warble and a cascade of clear, sweet notes. Its call has a sweet, nasal quality.
It is about 14 cm long.
