At least 35 species of birds call this rock city their home. These include the bald and golden eagles, hawks, horned owls, cactus wrens, roadrunners, and finches. Many of these birds nest in the cavities and crevasses in the rocks. Ground squirrels, chipmunks, jackrabbits, cottontails, kangaroo mice, and packrats also claim the city as their home. Coyotes are also frequent visitors to the park.
Snakes are very common in and around the park.
These include the Western diamond- back rattlesnake, the prairie rattlesnake, the mojave green rattlesnake, bull snakes, garter snakes, and occasionally, hognose snakes. Numerous varieties of lizards, including the collared lizard and the plateau lizard are also common in the park. Other familiar sightings include the desert tortoise, scorpions and tarantulas. Prehistoric people most likely camped thousands of years ago beneath the rocks that provided shelter from the elements and predators. Mortars - small, smoothsided cylindrical to conical holes, are found in the rocks along the trail in the northern part of the park as well as elsewhere.
