Mayhew 1947 Western Robin 5. May 14 U.C. campus, Alameda Co., Calif. on the nest, Still no sign of the other parent. at 6:20 P.M. I located another Robin's nest that apparently has just been completed. [illegible] it is about 12' above the ground on the east side of a Deodora tree just south of Hilgard Hall. May 15 at 1:50 P.M. an adult was seen to fly to the top of LSB with some food in its bill. it uttered low, clicking notes-3 or 4 at a time - at irregular intervals varying from 1 second to 10 seconds. Each time it uttered one of these notes, it bobbed its tail in a very pronounced manner. at 2:01 P.M. it flew to a near by tree and was lost from sight. May 16 at 9:00 A.M. when I arrived at the nest in the Deodora tree, I found one of the adults standing at the edge of the nest. It remained motionless for several minutes. at 9:16 A.M., the other parent, which was the ♀, chased the ♂ from the nest & proceeded to sit upon it, facing N.W. The ♂ flew to the ground about 30' from the tree & began the job of catching worms. The nest is constructed entirely of dried glass stems, at least on the outside. As yet, I haven't been able to determine how the nest is lined. At 9:37 A.M. a luck-tit began foraging in the branches within 10' of the nest without seeming to disturb the bird on the nest.
