(342) In these notes there will be found no claims of mimicry of sounds with which I am not able to identify positively. In this last performance I was surprised to hear the "Pitch-it" of the ground- squirrel. I thought nothing of it at first as it is a very common sound in this vicinity. But when it was repeated practically at my feet and then it was shortly followed by the confused cries of a whole colony of ground-squirrels when they are disturbed and Brownie's throat was pulsating and there was no other sound to be heard, then I decided that these creatures must be added to Brownie's score. The"pee'-yulk"of the flicker was included this time. (Hoffmann hears it as"tl'-err"). When Brownie stopped to catch yellow-jackets and spread herself out on the ground, like a hawk nailed to a barn door, after that. Greenie close by, but out of sight in the bushes, con- tinued the concert. As I passed by the oval lawn at 11:25 on returning to the house to enter this record, Snooty was at the finches' station eating seeds and swallowing them whole. 4:15 Snooty has not been seen often this afternoon. Greenie is also losing the small feathers at the base of the upper mandible. The wings of both adults are practically intact. suddenly Brownie has assumed a domineering attitude towards birds in the glade for some unknown reason. She chased a wren and a brown towhee away from the food dish when she wanted no food herself and did the same to Greenie, but that time she ate. She chased a brown towhee out of the brush and hazed Greenie three times--enough to cause him to leave the glade. Another time she appropriated the hole he was digging. He became shy of her and would not come to me for worms when she was where she could get to me quicker. Whenever she went near him he went on guard, sometimes opening his bill "haihing" at her. I do not know whether this portends anything or not. Greenie practised his undersong several times during the after- oon, but being more shy than his mate, stayed farther away, so
