Mayhew 1947 Western Robin 7. May 16 U.C. campus, Alameda Co., Calif. north-west direction. At 10:10 A.M. she left the nest, flying in a south-west direction. A moment later the or appeared from a tree about 150' away. He perched on the south edge of the nest. The ? was digging for worms about 100' from the nest. While sitting at the edge of the nest, the or uttered a weak, rather broken series of notes. They were so weak that at first I thought they were coming from a much greater distance. The notes went something like this: N N N. They were repeated over & over, then there was a break for a period of from 1 to 8 sec. between beginning again. Sometimes they increased in volume, but not often. At 10:18 A.M. the ? returned, chasing the or away with a couple of notes. She lit about a foot from the nest, then settled on it, facing south. At 10:30 A.M. she shifted her position so that she was facing north. The or was in the centre of the tree singing a series of rather musical notes somewhat like a mockingbird's. At 10:40AM he flew to a tree about 150' feet south of the nest, at 10:43 A.M. the ? stood up in the nest and seemed to shift the eggs a little. Then she settled back to her original position facing north. At 10:45 A.M. she began preening her feathers again, still staying on the nest. She stood up to preen the feathers on her breast.
