Cuban Vireo Vireo gundlachii

A small, slow-moving species that favors thickets and brush along forest edges and in scrublands. Typically found in pairs; sometimes joins mixed-species flocks with warblers and other vireos. Cuban Vireos have a “bulging eye” appearance created by the white crescent behind the eye and the dull yellowish spot in front of its eye. Also note its hefty bill, weak wingbars, and dull red eye. The similar Thick-billed Vireo has strong wingbars, a yellow spot in front of the eye, and darker eyes. The song is “chweee-ch-byuuu,” with the first note upslurred and last note downslurred. Its calls include a harsh “zzzhhh.”
