Primarily an insectivore, the San Blas Jay also feeds on fruit and lizards in various habitats such as mangrove swamps and dry scrubby woodlands. Other common names for the San Blas Jay include Geai de San Blas (French), Acapulcoblaurabe (German), Chara de San Blas (Spanish), and the Black-and-blue Jay.
