Prairie falcons breed in this area in some of the highest densities of anywhere in North America. Peregrine falcons have recently returned to the park to breed, also, but in far fewer numbers. A California condor re-establishment program has been in place since 2003. The first nest since reintroduction was built in 2010, and Pinnacles now manages a population of 25 free-flying condors. Mammals and birds that inhabit this park include prairie falcon, coyote, skunk, great horned owl, bobcat, California quail, raccoon, wild turkey, gray fox, golden eagle, and cougar.
