As we returned to the Greene Caves There were many Anderson Warblers and Birds. 19 species. Esp. Varied Thrush, G.c. Kinglets. Dec. 13: I heard a Grackle in the brush across Mosswood Rd. It called several times. Clear, Air crisp. Warm in the sunshine. Dec. 16: We drove to Boulder Creek and back. We stopped at Mt. View Marsh and Dumbarton Bridge on the way back. Mt. View Marsh: Tide 6:3 at 10:21 a.m. Reached the marsh at 3:00 p.m. Still plenty of water but birds were most numerous at some distance from road. Very abundant. Near the fence: Drabblers, Red-backed and Western Sandpipers, Some Willets and Bk. Plover. A few Godwits and both kinds of Curlew but these were more abundant farther out. Also Avocets, many more than earlier. More gulls than usual. I didn't see any Least Sandpipers near the road. It is the Godwit that shows the dark spot on the forward part of the wing when it flies. Dumbarton Bridge: Eared Grebes 250t, They were diving very actively as I could not tell whether the allons was there. Avocets - very closely bunched 350t. Willets 150t. No Sandpipers seen. 10 Pintails near roadway. No Pel, Egrets.
