A small loquacious inhabitant of scrubland, thickets, and brushy forest edges where it typically feeds within dense cover. The similar White-eyed Vireo can be distinguished by its smaller bill, greener back, and bright yellow sides; furthermore, adults have white, not dusky, eyes. The Cuban Vireo lacks the Thick-billed Vireo’s bold wingbars. The song is a scratchy jumbled “chick, didderwid-weee-zhee, chip” or variations thereof. Calls include a “zhip” given singly or in short bursts, a drawn-out harsh “zzhhe,” and a variety of chattering sounds.
