Mayhew 1947 May 27 Western Robin 35. U.C. campus, Alameda Co., Calif. At 5:50 P.M., when I looked into the nest in the Cedrus decodara south of Hilgard Hall, I found 2 newly hatched young + 2 blue eggs. The eggs were about 1½" long + about 3/4" though the greatest thickness. The two young were nearly naked, except for a few tiny downy feathers down the middle of the back. They didn't seem to be able to pick up their heads. When I climbed into the tree, the ♀ flew at me, coming within 4 feet of my head, uttering a series of alarm notes all the while. Even when I was walking away from the tree, she came swooping at me in one parting dive. The ♂ sat in the tree and uttered alarm notes, but he never tried to attack me. At 7:45 P.M. I returned to the nest near Oxford Circle. There was no sign of either the ♂ or ♀ anywhere around, and as it was almost dark, I think it is logical to assume that all of the eggs were unfertile, or else something happened to them. As the trunk of the tree is completely surrounded with blackberry brambles to a height of about 8 feet, I have found it impossible to climb up to the nest to determine it. At 7:55 P.M. I went to the nest in the live oak tree south of L.S.B. The one youngster that hadn't flown from the nest
