April 2018 - The San Francisco Bay Area Network monitors breeding prairie (Falco mexicanus) and peregrine falcons (Falco peregrinus) at Pinnacles National Park every year. Currently, pairs of both species are incubating eggs. Ten prairie falcon pairs have been confirmed, nine of which are nesting. Two peregrine falcon pairs are also currently incubating eggs. The number of nesting prairie falcon pairs this year is consistent with the 30-year average for the park, but it’s too early to know how peregrine falcon numbers compare to other years.
American kestrels, red-tailed hawks, red-shouldered hawks, great horned owls, long-eared owls, and barn owls are also nesting right now. The couple of golden eagle pairs currently defending territories do not appear to be nesting yet. Cooper's hawks and sharp-shinned hawks are also building nests, but these late-season breeding species likely won't be incubating eggs until May or June.
