The Great Basin collared lizard (Crotaphytus bicinctores), also known commonly as the desert collared lizard or the Mojave black-collared lizard, is a species of lizard in the family Crotaphytidae. The species is endemic to the Western United States.
C. bicinctores is very similar to the common collared lizard, Crotaphytus collaris, in shape and size, but it lacks the bright extravagant colors. Males can be brown to orange and some red or pink on the belly. Females are more black or dark brown. C. bicintores has elongated scales near the claws, and the tail is more triangular in shape than round as with C. collaris.
C. bicinctores has a broad head, large hind legs, and derives its specific name from the pair of black bands on the neck. Males have broader heads than females, with a dark-colored throat and more pronounced orange crossbands on the body. Adults range in size from 2.5 to 4.5 in (6.4 to 11.4 cm) in snout-to-vent length (SVL), with a thick tail that is often twice as long as the body.
The Great Basin collared lizard is endemic to the Western United States, and is found in California, most of Nevada, southeastern Oregon... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Desert Collared Lizard is recorded against all the reptiles logged in Grand Canyon National Park (78 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
