Long-tailed Brush Lizard
The Long-tailed Brush Lizard, Urosaurus graciosus, occurs in the Mojave and northern Colorado Deserts in the states of California, Arizona, Nevada, and also in Baja California. This species received its common name due to its tail, which is more than twice the body length, and since it is almost always encountered on a tree or shrub.
Its gray or tan coloration keep it well camouflaged against branches while it waits for insects. Unlike most other Phrynosomadtid lizards which bury in the sand at night, during warm weather, the brush lizard spends the night on the tips of branches. It is distinguishable from all other all other brush lizards (Urosaurus) by geography and choice of microhabitat.
