R.E. Johnson 1968 Song Sparrow Nov. 29 Tilden Regional Park, Contra Costa Co., Calif. Overcast, cool. 2:30 - 4:00 PM. Twice single birds were observed amid a flock of W.C. sparrows which had flown up to tops of weeds in weed patches when startled. Can't be sure if the Song Sparrow was in the weed patch all along or not. In each case it remained on a lower perch than the other birds & shortly disappeared under cover low in the weeds or on the ground. Further observations show that the Song Sparrow does feed among the WC & Golden-Crowned Sparrows on the ground in weed & grass cover. This cover is open enough to allow individuals to be followed as they forage, with binoculars, from a distance of 30 ft. away, yet it provides considerable camouflage & the birds could easily be overlooked. While the other species sit on the weed tops without moving, the Song Sparrow is nervous, constantly flitting its wings & tail & it usually moves on while the other species remain perched & still for some time. Weed species in field include mustard, dill, & thistle. Nov. 30 Berkeley Aquatic Park, Alameda Co., Calif. Overcast, sprinkling. One seen in bushes with W.C. & 6C Sparrows & Brown Towhee in two different locations. In each case when the other birds dropped to the ground to feed & then drifted away from the shrubs, the Song Sparrow stayed in the bushes perched 4 ft above the ground watching the others & finally returned into the bushes. It appears to be more reluctant than the Golden Crowned Sparrow to feed on the
