Mayhew 1947 May 16 Western Robin 9. U.C. campus, Alameda Co., Calif. in sight. The ? has remained very quiet on the nest ever since I arrived. She isn't nearly as restless as she was this morning. At 1:37 P.M. the ? left the nest & landed on the grass about 15' southwest of the nest. She immediately began to dig for worms. At 1:41 P.M. she returned to the nest, landing on a branch about 3' from the nest with a loud note, then settled down on the nest after uttering several low, rapid notes. The ? didn't put in an appearance to stand guard over the nest at all this time. The ? settled on the nest facing south-west. At 1:48 P.M. the ? uttered 3 series of very rapid notes on the same pitch while sitting on the nest. The ? landed in the tree about 10' from the nest right after this, then flew away to the south-east. At 1:54 P.M. a ? House Finch landed in the tree about 15' from the nest, but caused no response on the part of the ? Robin. At 1:55 P.M. the Robin left the nest again, returning to the tree at 1:57 P.M. when she landed about 8' above the nest. She then dropped to within about 4' of the nest, then settled on the nest facing west. May 19 At 11:55 A.M., an adult was sitting on the nest by Oxford Circle, still facing east. At 2:00 P.M. when I returned, an adult was still sitting on the nest facing east.
