Eastern Collared Lizard

Crotaphytus collaris

Also known as Common Collared Lizard, Oklahoma Collared Lizard, Mountain Boomer, Yellow-Headed Collared Lizard

Eastern collared lizards are athletic, rock-dwelling reptiles famous for sprinting on their hind legs at high speeds across sunlit glades and desert canyons. Dominant males showcase striking turquoise-blue bodies with bright yellow heads, using elevated boulders as lookout posts to survey territory and watch for rivals. When threatened, they display broad, gaping jaws capable of delivering a formidable defense against potential predators.

Responsible observation
  • Basking Spots: Scan prominent, sunlit rock ledges during warm mid-morning hours.

  • Territory Displays: Watch for male push-up displays and head-bobbing sequences on elevated rocks.
