Western Robin Mayhew 1947 May 27 U.C. campus, Alameda Co., Calif. in the afternoon was sitting up in the nest, but none of the others had returned to the nest.

The remiges, on the other hand, were about 4" long, with a feather sheath for about half their length over the base of each feather. The bright yellow edges of the bill that had been so prominent when the bird was younger, had disappeared. May 28 At 9:05 A.M. this morning, on examination of the nest in the live oak tree, I found the third youngster had also flown from the nest. Almost no excrement was found in the nest. At 2:20 P.M., there were 4 young birds in the nest in the Cedrus decidua tree south of Hilgard Hall. At 2:58 P.M. when I returned to the nest in the Cedrus decidua tree, the ? was standing on the west edge of the nest, facing east. [illegible] At 3:00 P.M. the ? settled upon the nest, facing north-east. The ?? was on the lawn about 40' from the tree. He uttered 3 single notes about 2 seconds apart. Then, at 3:01 P.M., he flew into the tree containing the nest. He landed on a branch about 25' from
