Mayhew 1947 May 8 Cedar Waxwing 2520 College Ave, Berkeley, Alameda Co., Calif. at 4:30 P.M. a flock of about 10 of this species landed in the western branches of an elm tree in front of the house. They began to feed on the young leaves that were just emerging from the buds. All the time they were in the tree they uttered weak, thin, high-pitched notes that seemed to be flocking notes. The top-knot, black patch through the eye and yellow tipped tail could all be seen easily. In only one bird did I see the red wax buds in the wing. They fed in a closely grouped flock — the entire flock didn't cover more than 6 feet square.
