Pecos is home to mammals ranging from the small Colorado chipmunk to the large elk. Some of the more common mammals you may see are the rock squirrel and the deer. Rarely seen, but can be present in the park are mountain lions and black bears. As you walk our trails, you may get lucky enough to see some of these creatures, or at the very least, the signs they leave behind.
Fish and Amphibians
Pecos is unique in that 3 miles of the Pecos River winds through the park boundary. This creates excellent habitat for fish and amphibians. The park has both native and non-native species of fish. Native fish in the Pecos River include Rio Grande chub and the longnose dace. Non-native fish that found in the river include rainbow and brown trout. Some amphibians found in the park include the woodhouse toad, New Mexico spadefoot toad, plains leopard frog and the tiger salamander.

Pecos is along the migratory route for some species of birds which make it a popular spot for birding. Birds such as the mountain bluebird and Steller’s jay are common sights along the Ancestral Sites Trail. Sometimes, if you look towards the river, you may catch a glimpse of a bald eagle flying overhead, trying to catch his dinner from the Pecos River.
The park is home to a few different species of reptiles. Lizards such as the short-horned lizard and the New Mexico whiptail lizard can be frequently seen around the park. Pecos has a variety of snakes inhabiting the park. Garter snakes, bull snakes, and of course rattlesnakes. Prairie rattlesnakes are commonly seen along the trails therefore caution is advised. Please report any rattlesnake sightings to a ranger.
