Western fence lizards are about 3 inches long with bits of blue on their bellies. Males are often observed doing a push-up like display to defend their territory and to attract females. Lizards are a staple food of snakes and birds of prey like hawks. Western fence lizards, a subspecies of the coast range fence lizard, have an interesting relationship with Lyme disease: Their blood contains a protein that kills the bacteria that causes Lyme disease. However, the lizards are a key host for ticks that carry Lyme disease, so there are more ticks in western fence lizard habitat.
