168 1937 Dec. 9. Chilly, overcast all day. (On the hill near the Studio there were flocks of robins, and Warblers & Ospreys Sparrow (fresh-water due to cold weather elsewhere?). Thrasher, Wrenlet, Song Sparrow singing. Went to Lake Merced with Lady Birds- Thousands of gulls on lams at Olympic Club Golf Course (which flies across the road just built by W.P.A. around the South Lake). When not feeding on the grass they bathed and loafed in the lake. Most of them seemed to be Cali. Gulls. The next most abundant bird was the coot but we found three Florida Gallinules. Scattered were Eared and Pied-billed Grebes and a number of Western Grebes which were giving all their calls. One lowered his head, reaching forward, and repeated a musical "pee-ee," pee-ee," many times and when he stopped raised his head again to normal position. Later two were sleeping next Together, one diving, the other remaining on the surface and repeating "pee-ee" as soon as the first bird rose to the surface and swimming toward the first bird with his head and shoulders and upper back just above the water and his feet sending up great splashes of water in their rear. This lasted until the first bird dove again. Then silence as long as he was down, but more calls and the same maneuvers as soon as number one appeared. Very few ducks; six Ring-necked Ducks in a close bunch, 3 males, 3 females (or young); 30 Baldpates; 15+ Ruddies. One bittern was flushed and one rail heard but not seen. Song Sparrow, Yellowthroat, Yellow Throats, and Brewer Blackbirds - One Sh. Sh. Hawk flying just above the Tules. 2 St. Blue Herons (our type) two Farallone Cormorants. Two disabled gulls.
