Cooper Hawk -- Saw one bird, but did not locate the nest said to be in the park. California Creeper Oregon Vesper Sparrow White-crowned Sparrow Slender-billed Nuthatch -- Found nest in stub of Acer macrophyllum at the lower end of the swimming hole at Avery Park. It is located about 51 species total 10 feet above the ground. The entrance faces east and is about 1 3/4" in diameter. The hole itself is about 6 inches deep. The male was bringing food to the nest and so I thought there must be young in the hole. In the afternoon I returned and found that the female was incubating the eggs and the male was feeding her. It was too dark in the cavity to see how many eggs there were. I spent an hour and a half timing the intervals of feeding to this nest. Results are below: I started timing at 2:58 p.m. and had not seen the bird at that time. His first arrival was at 2:56:30 2:41:45 2:42:15 2:43:45 2:45 2:51:15 High wind came up and continued for 2:52 rest of observation period. 3:02 3:04:15 3:06 3:07 Female came out of nest hole and perched on stub until 3:07:45 when she returned to the hole. 3:10:15 The male loitered at the spot where the female had perched 4 minutes before. 3:14 3:17:45 3:20 3:21:45 Male brought white grub about 1/2 inch long. 3:24:15 Male brought same 3:26:30 3:28:15 Left and didn't show up until 3:49 Did not return when I left at 3:58:30 The periods of long absence at 2:50 and at 3:50 seemed to be an hourly occurrence, the period of absence of which, was not of uniform length.
