DeBenedictis 1969 Aug. 8 Sacramento Valley near Davis, Yolo Co., Calif. Wilson's Warbler in Fresh Plumage. Bird listed in the 2nd column. From here we went on the standard waterbird circuit, back on Rt. 16 towards Woodlands. 2 1/2 mi from Elkhor Ferry stopped a Yolo Bypass where there is water and saw numerous waterbirds. 3 half-2/3 grown Avocets line. About 1/2-1/4 of all species were still in breeding plumage, except Phalaropes, Spotted Sandpipers. We then went 2 mi. to Road 102 N 1 mi. to Speckles Sugar Ponds. Very little water and almost no birds were there; then 5 on 102 c. 6-8 mil to Davis Sewer Ponds (1 1/2 mi. W Davis) Lots of Tree and Cliff Swallows here, but very few Shore Birds (2 B.B Plouer in nupt. plumage). Very poor. Went to Davis, then back out 102, 2 mi. from city limits to Yolo Bypass on Rt.28, and out along the Yolo Bypass. Here water either to Shallows or to clipp, and virtually no birds of any sort seen. Birds seen after the land birding on 3rd column. We left here & arrived Berkeley c. 4:15 and went to the Toll Plaza where we looked around rather casually for a while. Peep not very conspicuous, but lots of Forster's Terns. Tide was about + 4.0 and most of the birds were out on the mud & I had to come back. Found an Old Kildeer's Nest. The Western Flycatcher was in Berkeley near the golf club, the first I have ever seen here. Fairly good day!
