Mayhew 1950 April 22 Conway Ranch, 2 miles east of Woodland, Yolo Co., Calif. three weeks. The Stilts have not as yet anywhere near approached the numbers that were present last year. I saw no evidence of either of these species nesting yet. I spent the afternoon numbering all the new nests of Cliff Swallows under the Poleline Bridge near the western edge of the ranch. There were 111 new nests and 6 old ones that had been repaired. The birds seen today were: Cliff Swallow-1 Barn Swallow-3 Mallard-2 Cost-3 Pintail-4 Shoveller-3 Canvasback-4 Florida Gallinule-4 Red-tailed Hawk-4 Red-winged Blackbird-1 House Finch-2 Marsh Hawk-4 Snowy Egret-4 American Egret-4 Cali. Gull-3 Great Blue Heron-3 Meadowlark-3 Marsh Wren-4 Pheasant-3 Cinnamon Teal-4 Avocet-2 Black-necked Stilt-3 Crow-14 Pied-billed Grebe-4 Least Sandpiper-1 Red-shafted Flicker-4 Brewer's Blackbird-2 Farallon Cormorant-4 Mourning Dove-4 Greater Yellow-legs-3 This makes a total of 30 species seen. A number of these birds were seen in fields that are just being flooded for rice.
