It has once been documented as a vagrant in Texas. == Taxonomy and systematics == The Yucatan vireo was originally described in 1871 as Vireosylvia magister. The Yucatan vireo's further taxonomy is unsettled.

The Yucatan vireo, the red-eyed vireo (V. olivaceous) and several other vireos form a superspecies. This article follows the four-subspecies model. == Description == The Yucatan vireo is about 15 cm (5.9 in) long and weighs about 13.5 to 25 g (0.48 to 0.88 oz). The sexes have the same plumage.
