The island scrub jay (Aphelocoma insularis), also known as the island jay or Santa Cruz jay, is a bird in the genus Aphelocoma, which is endemic to Santa Cruz Island off the coast of Southern California. Of the over 500 breeding bird species in the continental U.S. and Canada, it is the only insular endemic landbird species, meaning it is restricted to a geographical island.
