Habitat: The habitat encomapsses lowland desert and arid-tropical thornscrub mountain ranges; the species is always associated with rocks, such as granitic outcroppings or volcanic flows. In the northwestern part of the range, this lizard often perches on granitic rocks in sandy washes at the bases of rocky hillsides; in the south, it may be concentrated in arroyo bottoms and less vegetated valleys.

Range: Ranges from southwestern Arizona southward in Sonora, Mexico, to the Guaymas region; probably stable; no known significant threats; recognized as a distinct species in 1996.

Found in these States: AZ | NM

Diet: Not only do they eat insects such as grasshoppers and crickets, but they also eat other lizards, including other collared lizards!

Reproduction: C. nebrius is oviparous. Mating takes place probably primarily in May to June; neonates apparently hatch out between July and/or August and September, at least in the north

Status: Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
