Tree Lizard
Tree Lizard NPS Photo Urosaurus ornatus Body length: 1 1/2 - 2 1/4" Diet: Insects and spiders Tree lizards might just as appropriately be called "rock lizards". At Tonto National Monument, as in many other areas, they are most commonly seen on boulders and cliffs, including the walls of the cliff dwellings. Tree lizards are generally drab-colored, blending easily into their surroundings. However, during the breeding season (spring and following the summer rains) male tree lizards can be seen out doing "push-ups" with all four legs. These push-ups flash the male's bright blue undersides, advertising his availability to potential mates. |

Tonto National Monument is home to a crested saguaro. Biologists disagree as to why some saguaros grow in this unusual form. Some speculate that it is a genetic mutation. Others say it is the result of lightning or freeze damage. About one in 150,000 saguaros develop this unusual growth.
