140 1937 Jan. 19. Went to Boulder Creek via Dunbarton Bridge and Mt. View Marsh. Between Alvarado and saw two large flocks of Savannah Sparrows (50+ and two flocks of Black-bellied Plover (30+ each) in the fields; also a Duck Hawk. At the bridge on the Salt pools about 300 Rared Grebes - scattered instead of being all in the last pool on the right, some were on the left where the wind was less strong (north wind, clearing after rain). All three kinds of Sandpipers were present - and in large numbers but scattered - it was low tide. A number of Black-bellied Plover, Willets and four large tanny birds in the distance acted like Godwits. There were a few ducks: pintails, reddies, shorellers. No egrets, pelicans or avocet. At Mt. View Marsh (tide low) there were many shore birds: Sandpipers, Dowitchers (40+), Bb. Plover, Willets, Hudsonian Curlew, Long-billed Curlew (6 feet) and one Godwit and several Yellowlegs - two of them decidedly smaller than the Willets which were next to them. There were more ducks in the marsh than at the bridge - but probably not more than 100 within range from the highway where we were parked. Worked in the garden at Boulder Creek. Saw a flock of about 200 Band-tailed Pigeons disappear over the Summit of Ben Lomond about 4:30 p.m. Counted eight flocks of Juncoes between Saratoga and the cottage. Saw one Turkey Buzzard near Saratoga. Weather was very cold as we spent the night at Santa Cruz.
