ITIS Reports — Odocoileus hemionus cerrosensis ITIS (the Integrated Taxonomic Information System) is a source for authoritative taxonomic information on plants, animals, fungi, and microbes of North America and the world. The Cedros Island mule deer (Odocoileus hemionus cerrosensis) is a subspecies of mule deer found only on Cedros Island off the coast of Baja California. Only about 50 individuals remain, with no captive population. Its behavior is similar to that of other subspecies of mule deer. The subspecies is threatened by feral dogs and poaching. The Cedros island mule deer shows a reduction in body size and antler size compared to mainland deer, which is an effect of isolation in a relatively small island, according to the “island rule” of Leigh Van Valen. There are also differences in fur coloration which distinguish cerrosensis from other mule deer, but most closely resembling Odocoileus hemionus fuliginatus.
