The Shasta Alligator Lizard is a subspecies of the Northern Alligator Lizard. They are known to eat a variety of small invertebrates, including insects, spiders, millipedes, slugs, snails, and worms. It will also eat small lizards and small mammals and will occasionally feed on bird eggs and young birds.
Alligator Lizards are generally secretive, tending to hide in brush or under rocks, although they are often seen foraging out in the open or on roads in the morning and evening. They will often take refuge in crevices, rock fissures, and mammal burrows.
