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.

Formerly native animals, now vanished from most of central California, included tule elk and pronghorn.
Grizzly and black bears were in the area until the end of the 19th century.

Like many parks in central California, Pinnacles has had a small problem with wild pigs (a mix of feral domestic pigs and imported wild boars) disturbing the landscape on a regular basis.
 As of spring 2006, the core of the park was pig-free.
 The culmination of a twenty-year, $1.6 million effort had succeeded in eradicating pigs from the main area of the park.
National Park Service personnel along with IWS worked to remove pigs from inside the park, and establish and monitor an exclusionary pig fence that runs for approximately 26 miles (42 km) around the center core of the park.
Outside this fence, however, wild pigs still roam in regular abundance.
Current monitoring for potential breaks and breaches in the fence is needed to ensure that the pigs do not return to devastate the park.

Thirteen species of bats have been documented at Pinnacles, with a further three species considered likely.
The park's talus caves provide roosting and breeding habitat for the bats.

In the 1990s, a student biologist, Olivia Messinger, did a census of bees at Pinnacles.
 She found that the park has more bees per unit area than known anywhere else on earth, around 400 species.
 Most of these bees are solitary bees, not living in colonies like European honeybees, and most live for only three to four weeks, and since flowers bloom here throughout the growing season,  many niches are available for all the bee species.

The diversity of intersecting ecosystems and altitude has led to great number of animal species that call the park home.
