1948 Bucephala clangula 1 Nov. 25 - Just N base of St Isabel, SC part of Richmond, Contra Costa Co., Calif. - 3 birds in ? plumage (of this sp. or B. islandica) were diving in active fashion & in rapid succession in the small part of tide flat area between big dike and the highway. The tide was flowing out thru the only gap in the dike quite rapidly & after a few minutes, the golden eyes worked out with it into the main part of the bay. Nov. 27 - Jewell Lake, Tilden Park, Contra Costa Co., NE of Berkeley, Calif.. one female seen. It flew up with other ducks at our approach to the west shore; but, whereas the others disappeared from the vicinity, the golden eye circled back over the pond (at about 150 to 200 ft. alt.) several times. We went on up the hill after that & I don't know whether she actually landed in the pond again or not. Dec. 5 - 2 females were on the pond - and stayed there despite our walking slowly & in plain sight along E. & N. shores. Another ? came in to the pond after we were there for some time. At one time, when one ? was flying up to just cross the pond, I heard a slight whistling from her wings. It does not seem nearly so prominent as that I heard
