About the Eastern Collared Lizard

The common collared lizard (Crotaphytus collaris), also commonly called eastern collared lizard, Oklahoma collared lizard, mountain boomer, yellow-headed collared lizard, and collared lizard, is a North American species of lizard in the family Crotaphytidae. The common name "collared lizard" comes from the lizard's distinct coloration, which includes bands of black around the neck and shoulders that look like a collar. Males can be very colorful, with blue-green bodies, yellow stripes on the tail and back, and yellow-orange throats. Five subspecies are recognized.

The subspecific name, baileyi, is in honor of American mammalogist Vernon Orlando Bailey. The five subspecies recognized as being valid, including the nominotypical subspecies, are: Crotaphytus collaris auriceps Fitch & W. Tanner, 1951 – yellow-headed collared lizard

C. c. baileyi Stejneger, 1890 – western collared lizard C. c. collaris (Say, 1823) – eastern collared lizard C. collaris fuscus W. Ingram & W. Tanner, 1971 – Chihuahuan collared lizard C. c. melanomaculatus Axtell & Webb, 1995 – black-spotted collared lizard
