Field Notes D. A. Bell April 8, 1990 14:00 - 14:20: at Squaw Rock, Highway 101, 10 mi. S. Hopland, CA; Mendocino Co., CA. Lots of evidence of Peregrines "in residence" on the rock. Whitewash on many places, including its shelf area where they have nested before. Maren thought she heard peregrine screaming, and I did to, when a raven flew in to the traditional stick nest at lower left corner of rock face. The raven hopped hopped onto the back of its incubating mate, appeared to feed it by regurgitation, and the mate. 17:15 - 17:45: at Redway Rocks, along Briceland Road, ca. 5 mi W of Redway, Humboldt Co., CA. Set up on bluff behind road, looking across creek towards the cliffs. After about 10 min. heard whirling screams - sounded like hungry female. Screams were coming from left series of cliff. Last year they were on the right series of cliff. Then heard male scream. Saw him fly in front of cliffs. Falcon (?) appeared at small pothole on left cliffs. When I went to switch from binos to scope, she was gone, but the tiercel continued across the cliffs, soared up above the ridge line, then powered off to the SE along the creek drainage.
