About the Yucatán Vireo

The Yucatan vireo (Vireo magister) is a species of bird in the family Vireonidae, the vireos, greenlets, and shrike-babblers. It is found on Grand Cayman and in Belize, Honduras, and Mexico. It has once been documented as a vagrant in Texas.

The Yucatan vireo was originally described in 1871 as Vireosylvia magister. The Yucatan vireo's further taxonomy is unsettled. The IOC, AviList, and BirdLife International's Handbook of the Birds of the World assign it these four subspecies:

V. m. magister (Baird, SF, 1871) V. m. decoloratus (Phillips, AR, 1991) V. m. stilesi (Phillips, AR, 1991) V. m. caymanensis Cory, 1887 However, the Clements taxonomy does not recognize V. m. decoloratus and V. m. stilesi but includes them within the nominate V. m. magister.

The Yucatan vireo, the red-eyed vireo (V. olivaceus) and several other vireos form a superspecies. This article follows the four-subspecies model. 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. Adults of the nominate subspecies V. m. magister have a pale brownish white supercilium and brownish gray lores; the... Wikipedia →
