What kinds of animals live within the Reserve?

Are there snakes?

We have over 370 species of birds, brush rabbits, jack rabbits, lizards, squirrels, grey foxes, and coyotes. In the Border Field area you may still find the bobcat but it is unusual. We do have rattlesnakes but they are rarely seen north of the river and are more common at Border Field. Stay on the trail when hiking. The California kingsnake, a natural predator of the rattlesnake, is commonly seen when the temperature is warm enough. The California kingsnake is not dangerous to humans. Find out more.
