Journal Strawberry Canyon, Alameda Co., Calif. 04.6 On the previous evening I set 40/10' folding Sherman Live Traps along a path running down Strawberry Cr. (see MAP). The traps were set between 6:00 PM and 7:00 PM at night. The sky was clear, temperature in the 70's. Quaker Oatmeal was used as bait. The habitat was Riparian woodland, Quercus agrifolia and Umbellularia californica making up the overstory. Traps were most frequently set in Blackberry thickets. Few holes were visible. I sprinkled a few oats in front of each trap. The moon was over 3/4 full and was still in the sky at 6:30 AM. This morning I began collecting traps in the darkness at 6:35 AM. The sky was clear, and the weather was mild, about 60(?). I caught nine Peromyscus sp. in the first 21 traps. Only one more was caught in the last 19 traps, this being near the creek. The last half of the trap line was higher, and farther from the creek, therefore drier. Most mice were taken in very wet soil, near the stream, but none actually in the stream bed or on its banks. Some mice are Peromyscus truei. Others, sometimes, only Le Peromyscus truei or P. californicus.. No other species were taken. 1972 Audubon Society Bird Sanctuary, Belvedere, Marin Co., California October 9 I saw a flock of approximately 20 golden- crowned sparrows atop the hill which comprises the refuge. They were mostly taking shelter in the brush, for the sky was overcast.
