|Adult in Mexico|
Range and habitat
It is found primarily in the Yucatán Peninsula, which comprises the northern part of the nation of Belize; and Guatemala's northern El Petén Department and the Mexican states of Yucatán, Quintana Roo and Campeche. It is also present in parts of the neighbouring states of Chiapas and Tabasco. Its natural habitats are subtropical or tropical dry forests, heavily degraded former forest, and plantations up to 250 m (820 ft).
The jays approximately 30 cm (12 in) long. Adults are black, with cerulean blue wings, mantle, and tail. They have black bills, yellow eye rings, and yellow legs. Juvenile Yucatán jays have completely yellow bare parts and white, rather than black, body plumage. They molt out of the white plumage by September or October, but retain the yellow bill and eye ring for a few more months. They also have pale-tipped retrices, which the adults lack.
