1 mi. W of Elk Grove, at Sea level, Humboldt Co., Calif. June 11, 1946 over, forming a funnel about 4 feet above the water surface. Twenty additional traps were set in the dry woods about 1/4 mile west of the sawmill. The undergrowth was sparse, mostly Vaccinium. June 12, 1946 Trap line caught 1 Song Sparrow in the gress by the water's edge, 1 immature P. waniculatus, caught in a trap set on a moss-covered log lying across the stream, 1 Microtus oregoni caught in a trap set in a run about 3 inches below the sur- face in the mud on the creek bank, and 4 Sorex pacificus, caught at the water's edge on the grassy creek banks. One Sorex had a smashed skull and was discarded. The 20 traps in the woods were blank and were picked up. Shined in a.m. and set 20 traps along the creek below the 30 I had set yesterday. In the evening, which was foggy, we heard several birds flying high, above the fog, and giving high, squealing notes. The only bird we can think of that would be flying inland fairly late in the evening (c. 8:00 p.m.) is the Marbled Murrelet which has been heard in this vicinity
