Body length: 24 - 67"
Diet: Birds, lizards, and frogs
This conspicuous day-active species is common throughout Tonto National Monument. If you see (very briefly!) a greenish-gray snake streaking away from you on the trail, the chances are good it's a Sonoran whipsnake. The whipsnake's keen eyesight and speed are used to chase down lizards and other prey.
Whipsnakes seem to be as comfortable in trees as on the ground, and they may be an important predator of birds such as cactus wrens and thrashers. Other food items include frogs, rodents, eggs, insects, and even carrion. When captured by humans, whipsnakes bite aggressively, often drawing blood. However, they are not venomous or harmful in any way.
