Cogswell 1950 4 Journal Feb 5 C side Yolo Basin, Yolo Co., Calif. (contd) - the first time I had ever seen it so. There were many ducks but widely dispersed here and there across the extensive lake so formed. Mallards were common, Pintail & baldpats less so, and a few Geese & Canvasbacks were seen; also 17 Golden eye (with bright yellow-tipped bill) on the turbulent water of the channel along the leese. 15 Whistling Swans were noted. Of major ecological import was the con- spicuous concentration of Jack Rabbits and Ring-necked Pheasants on the few remaining dry spots. July 25 jacks and over 15 cock pheasants were on one island not over 300 ft. long, a marsh Hawk was having good hunting there also with frequent rops to the ground - but neither of the species mentioned were bothered by it. Presumably there was a concentration of more also. 3 Cooper's Hawks were seen of a few Red Tails in the thin stands of leafless willows along the channel or flying out over the water itself. Several Crows and many gulls were also apparently participating in the harvest. Land-birds noted along here were: Red-shafted Slicker, Black Phoebe, Meadowlark, Red-wing Brewer's Blackbird, House Finch, Dim Goldfinch (many), Savannah, White-crowned, & Song Sparrows.
