Cogswell 1949 Fallo columbarius Nov. 6 - 1/4 mi. W, 1/2 mi. N Newark Alameda Co., Calif. an immature plumaged bird sat on a 3-5" chunk of dead cow dung in a dry pasture along the road here as we drove by, backed up & looked at it. They 9x binoculars its light supercilary and light nuchal areas were easily seen; there were also two rows of brown edges (of scapulars?) prominent against the dusky brown of its general plumage as it faced away from us. As I got out of the car it turned around & I noted the dusky streaks of the under parts, and as it flew presently, the banked tail which had been covered by wing tips in the perched bird St alighted on another clod further down the pasture, but soon flew again to a fence post along the RR tracks between the pasture and Leslie's salt Co's salt ponds. Large flocks of blackbirds were flying about nearby farms — the only probable bird concentration attractive to this remark which I noted at this point except some few were pipits. But it chased nothing while we watched. This is the same location at which we see Burrowing owls regularly. Dec. 11. 3 1/2 mi. SE Gustine Merced Co., Calif. 1 ad. seen at range of 40 ft., as it perched on 1 fence post after another while it attempted to eat a Least Sandpiper (leg retrieved by me).
