April 26, 1942 7:30 to 10 a.m. and 2 p.m. to 2:15 p.m. Cloudy, no wind, sunny, and cold in earlier morning. With bird club on hike to Avery's Park California Creepers -- A pair of them working the fir trees in the park. Both of their breasts were a very clean white color. They got together and put their bills together for a few moments while we watched. Robin Meadowlark Junco Golden-crowned Kinglet Lincoln Sparrow -- In brush pile. Looked much like song sparrow except for the lack of streaking on the chest and belly. Instead there was a small oval brown patch in the center of the chest that was smaller and finer than the one on the song sparrow. I didn't see any buffy band, Dr. Gordon. Audubon Warbler -- Hundreds of them in the trees feeding on the buds and possibly on some insects. The males were in brilliant plumage. Cassin Vireo -- The woods was full of them this morning. Gairdner Woodpecker Song Sparrow -- Black-throated Gray Warbler Killdeer Purple Finch Chipping Sparrow Red-breasted Nuthatch Seattle Wren Oregon Towhee Lutescent Warbler Valley Quail English Sparrow Townsend's Warbler -- I found this one within 15' of where I was standing. It was feeding with the Audubon's, and it might easily have been confused with them. The general body color seemed to be a blue gray, but the distinct gold lines on the side of the head showed up well. It was the first one that I had ever seen. Bob Buchanan saw it also. Violet-green Swallow Western Evening Grosbeak Pine Siskin Hermit Warbler -- Dr. Gordon thought he saw a female several times in the upper branches of a fir tree, but distance made it an unsafe observation. Cooper's Hawk and nest: Located nest in top of Ash Tree. In afternoon my roommate and I investigated the nest and he climbed up to it. It was 81' above the ground. The nest base was made of long twigs that were not over 1/4" in diameter. The cup of the nest is about 4" deep at the center and is about 3" wide at that level and is about 8" wide at the surface. The cup had some twigs with needles of fir attached and the rest was just plain twigs. There were two eggs in the nest which were laying side by side with the pointed or tapered ends to the south and the blunt ends to the north. They were a light blue green color (lighter than a Robin's egg.) The size of these eggs was about 1 1/2 to 1 5/8" long, by 1 or 1 and 1/8" inches wide. The female was not on the nest when he started up, but came back soon after, scolding, and then being quiet for the remainder of the time. Evidently the set is not full.
