Mayhew 1947 Western Robin 2. May 7 U.C. campus, Berkeley, Alameda Co., Calif. 2:10 P.M. when I looked again. The weather is fairly warm, so apparently it is all right to leave the eggs alone for a while. May 8 It appears that incubation has begun because one of the parents was seen on the nest every time I looked at it today. I looked at the nest at 9:05 A.M., 11:55 A.M., 2:10 P.M. + 6:10 P.M., and the bird had apparently not changed position all this time. 2520 College Ave, Berkeley, Alameda Co., Calif. at 3:00 P.M. I began watching the parent birds bringing food to the young in the nest in the hack-eye tree. The food this afternoon has consisted of worms of unidentified species and some corolla petals of the hack-eye tree. The young are almost completely covered with down now, and are able to stand up and flap their wings a little. They can be seen exercising and primping their small feathers between trips by the parents. at 3:55 P.M. one of the parents left after bringing some food. As yet, there has been no sign of the other bird arriving. at 4:13 P.M. one of the parents landed in a tree about 120' south of the nest. On four stages it arrived at the nest a minute and a half later. It landed in the tree about 30 feet from the nest before it actually went to the nest, at this point, the young stood up and uttered a series of rolling notes. The parent had the young seed pod of some.
