Cozumel Vireo

The Cozumel vireo is 11.5 to 12.5 cm (4.5 to 4.9 in) long and weighs about 11 to 14.5 g (0.39 to 0.51 oz). The sexes have the same plumage. Adults have a dark chestnut-brown crown, nape, and ear coverts. They have an off-white patch from the lores to the eye and a wide white eye-ring; together they look like spectacles. Their upperparts are light chestnut-brown. Their wing coverts are gray-brown with wide yellowish-white tips that form two bold wing bars. Their flight feathers are gray-brown; the primaries and secondaries have greenish or olive-yellow edges on the outer webs and the tertials have whitish edges. Their tail is brownish gray with greenish edges on the outer webs of the feathers. Their chin and throat are off-white, their breast off-white with chestnut- or cinnamon-brown sides, their flanks brownish, and their belly and vent off-white. They have a brown iris, a pinkish bill with a darker tip, and lead-blue, bluish pink, or dusky pinkish legs and feet. Juveniles are overall paler than adults, with purer brown sides of the breast and a darker brown iris.

The Cozumel vireo is found only on Cozumel Island off the coast of the Mexican state of Quintana Roo of the eastern Yucatán Peninsula. It inhabits scrubby woodlands and similar landscapes such as brushy abandoned fields, young secondary woodland, and thickets in more mature woodland.

The Cozumel vireo's diet has not been studied. The species typically forages in low to middle-height vegetation.
