1938 Oct.26. Dense fog. Oct.27. Foggy. Crowned Sphasows decreasing. Oct.30. Stopped on way home from Boulder at 11:34 a.m. Crush at Mt. Vird Marsh. Tide was out but since it has been raining all night and was still raining there was considerable water near the highway. One Clapper Rail was outside the fence within six or eight feet of the car. And close views of the other birds listed were easily ob. Tamed. Redbacked Sandpipers were present in numbers and with them were both Least and Western. Dowitchers too were in larger numbers - perhaps 40 alls- together. Black-bellied Plover and Willets were less abundant than hitherto and also Longbilled (3+) and Hudsonian (6) Curlew. Godwits were abundant (40+). I saw no Yellowlegs or Avocets. At Dumbarton Bridge at 1:08 p.m., The sloughs were empty (west end) and mice rails (Clapper) were seen. Also many Sandpipers. On the Salt Pools at the East end about 200 Eared Grebes, 1000 Willets (looping in shallow water) and a great many Redbacked Sandpipers (mixed with Willets). I saw no Avocets or Godwits but light was poor because it was so cloudy. No Pelicans.
