Unicolored jay
The unicolored jay (Aphelocoma unicolor) 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 (Rice et al. 2003). At Montebello, Chiapas, it is a cooperative breeder (Webber and Brown 1994). References
