Collard lizards are medium-sized, diurnal, rock-dwelling desert lizards with large heads and a dark collar around the neck. They are usually seen sitting on top of rocks. Typically, they will run away quickly when approached, then return to their spot after a few minutes. Occasionally you will see them running on the ground, usually between large rocks.
Two species of collared lizards are found in California. Check the range maps below to determine which one is in your area.
