Collared Lizard

Did You Know?
Lizards, including the colorful collared lizard, are one of the most frequently seen animals in Canyonlands. When not chasing flies or basking in the sun, they are often seen doing what appears to be push-ups. Scientists believe this and other behaviors signal dominance and facilitate courtship.
