March 2019 - It’s raptor breeding season in Pinnacles National Park! So far, raptor monitoringstaff and volunteers have observed eight pairs of prairie falcons, and one single prairie falcon, occupying nesting territories and actively inspecting cliff cavities for potential nesting sites. Three peregrine falcon pairs have also been confirmed occupying territories. The park’s annual raptor advisories, which help people avoid disturbing the birds during this sensitive time, are now in effect.
Adding to this season’s excitement, staff have confirmed that a golden eagle pair is nesting and incubating eggs at North Chalone Peak. These impressive birds were last confirmed nesting in the park six years ago, in 2013. Like prairie and peregrine falcons, golden eagles are cliff nesting birds sensitive to disturbance. They are a fully protected species in California.
Many other raptor species have been active in Pinnacles’ bottomlands. In particular, red-shouldered hawks have been vocal as they build their stick nests. A pair in the campground is finishing construction of a nest high on a valley oak near the visitor center and the overflow parking lot. American kestrels, red-tailed hawks, great horned and barn owls, and Cooper's and sharp-shinned hawks have been spotted in the park early this year as well.
