Remsen, J.V. 1978 Northern Saw-whet Owl Aegolius acadicus March 11 Coyote Hills Reg. Park, Alameda Co., Calif.: I sitting in small, dense ornamental tree on lawn at visitor center where it was found earlier this morning. It was approached to within a foot, as it slept on a small horizontal branch at the lower edge of the tree about 7 ft off the ground. It was perched about 2 feet in from the outer shell of the foliage. The tree had fairly dense foliage. This is almost certainly a migrant at this locality, which has only small patches of low trees and a few tall planted pines. March 29 Coyote Hills: 2 birds in separate trees- same area. Apr. 29 Mt. Palomar St. Park, San Diego Co., Calif.: I at entrance to Fry Creek Campground; responded vigorously to imitations- it dove at me 3 times, coming within inches of my face - but we could never get a light on the perched bird.
