The unicolored jay is an Aphelocoma jay native to cloud forests of northwestern Central America and southern and southeastern Mexico, from central Honduras west to central Guerrero, southern Veracruz and extreme southern San Luis Potosí. It is apparently a basal member of its genus. At Montebello, Chiapas, it is a cooperative breeder, and is not known to perform mating dances.
