Bulwore, ET 1941 May 24 Russian Gulch State Park, 40 ft., Mendocino Co., Calif. Spring. One Peromyscus was discarded; we had to kill it in the trap, and it was in an unspecimen-like condition. We hear the call of the Russet-backed Thrush near camp from sunup to sundown. The ranger's small son brought us a Mus musculus caught in their house. Its skull was crushed, therefore animal was not prepared. May 25 Traps set by Frances and me last night in meadow stop hill south of camp and sloping NW toward the ocean. Museum specials baited with walnut; 25 set in damp tangled brush on edge of meadow and in the meadow. Brush consisted of Chinquapin, thimbleberry, blackberry, gooseberry, Baccharis, wild rose, Echinocystis, and some thistle. In most places brush thick and briery. In spots of meadow traps set in, grass 3 ft. tall, but short and probably grazed over most of the meadow. Small clumps of Baccharis, Avena, mints, Compositae, blackberry, and strawberry mixed in with grasses. Meadow has slope of about 15° and drains off well - no standing water. On the northern canyon edge of brush is mixed forest of Abies grandis, Alnus rubra, and Pinos muricata and Pseudotsuga taxifolia. We caught 1 Microtus in the meadows; 1 Zapus orarius, 1 shrewmole, and 2 Peromyscus maniculatus. Something ate part of the shrewmole leaving only skull fit for preparation.
