April 30, 1949, Lake Washington, Yolo Co, W of Sacramento - 9-945 a.m. 3 pair Farallon Cormorants Great Blue Heron Mallard - pair with a female Ruddy Duck Marsh Hawk doing love-dives Sparrow Hawk Pheasant hen on nest in "broadleaf-mottled-thistle" area, which had been trampled down by a truck, so the nest was fully exposed to the south, whence I viewed it. The first time I came within 3 feet and she didn't flush, but when I came in with a camera to 3' she flushed. I took a pic of 12 eggs, very fresh-looking. Coots Tree Swallows Barn Swallows Western Crows Suisun Long-billed Marsh Wrens Yellow-headed Blackbirds - 1st I have seen. They have moved in since my last visit - about 6 pair seen. In cattail areas, in deeper water, only. Calif. Bicolor Redwings - very common Western Grasshopper Sparrows - saw 2 pairs in dense herbaceous vegetation at edge of alfalfa fields along west side of lake. (Ammodramus savannarum). Calif. Interior Jay - pair have nested in vine on south side of Judd's house at 2228-3rd Avenue. Nest against the house, but built in the vine. Very well-sheltered by the leaves of the vine. This part of house shaded by large white oak over the house. Each time I looked, a parent was on the nest, even in the afternoon. The other adult came to the nest, and fed the brooding adult. No noises were made. Then the brooding bird saw me and left in a hurry, tumbling very naked, still-blind, young about in the nest. One ended up up-side-down on the rim of the nest. Atthis moment, the adult that had been feeding the brooding adult just"froze"at the edge of the nest, and made no movements for quite some time. There seem to be 4 young in the nest, although I can not be certainfrom the view I had.
