2 mi. W. Hyamson, 1200 ft., Trinity Co., Calif. June 5, 1946 Trap lines yielded 1 Peromyscus maniculatus, which was discarded, and 2 Peromyscus truei (1768+1769) which were saved. The P. truei were both caught in sets near a stream, one under a shrub and the other at the base of a small rock. Hunted birds in an irrigated field below camp, about 1/4 mile ENE. The field comes right to the edge of the bed of the Hayfork River. The river side of the field is bordered by dense, massive tangles of Vitis, alternating with dense, low thickets of Salix sp., and scattered cottonwoods and Garry Oaks. The camp side of the field is bordered by a fairly continuous strip of Garry Oaks backed by Douglas fir and yellow pine. Several Song Sparrows were heard singing in the willow thickets on the river side. One (1770) was collected. Allen Hum- ingbirds were seen on both sides of the field. One (1772) was shot as it perched on the very top of a dense grape tangle. A female was wounded close by, but was lost in the under cover. These 2 hummers were both on the river side of the field. Purple finches were seen and heard on both sides of the field. 2 (1773+1774) were taken, both in oaks but on opposite sides of the field.
