V. Memmels 1941 Band-tailed Pigeon May 23, Russian Glenn State Park, Pine Barrens, Mendocino Co., Calif. elev. 500' 1:30PM. Sunshining About 150 or more birds were perched on Pinus muricata trees and old snags. They were frightened by our approach and took to the wing. They make a flapping noise in flight as if their wings were clapping together above or below. The noise is especially obvious as the bird begins to fly. When established in flight the clapping noise occurs only rarely. Their flecgat has very rapid wing beat.
