Koford, R. 1976 Journal White Cloud campground, 4300 ft, 11 mi. E Nevada City (by rd.), Nevada Co., Cal. 10 April I spent 0545-0800, 1130-1230 in the first study area, hearing 3 chirring calls in the early morning. The first couple hours of the day were partly cloudy, cold, with southerly winds. Then the sky became completely overcast. It started raining at about 1330, snowing at 1430. The snow continued all afternoon. 11 April I spent 0655-0800, 1030-1100 in the study area, hearing one chir and seeing a squirrel in the campground. Also, I saw Gray Squirrel tracks and Chickaree tracks in the study area, and saw one Gray Squirrel eating insect larvae from swollen twigs at the end of oak branches. It snowed several hours in the morning, then stopped, but dripped constantly. This wiped out tracks and made walking around uncomfortable, so I left around noon, with about 3 cm. of new snow on the ground - none under the feet. 16 April I arrived last night, parking in the campground which is now open- no payment required yet. I then spent 0830-0900, 0945-1215, 1730-1845 in the first study area. In addition, I checked the traps in the study area for ~10 min at 1330, 1500, and 1630. I set 15 traps in the N part of the study area between 1000 and 1100, closed them at 1630. I also spent 1245-1700 largely outside, in the campground, so I could hear squirrel calls. At 1330 I found a Beechey Ground Squirrel in a trap between C1 and D1, a female. I let her go and she ran N. Then I heard a chirring call somewhere near A1. Looking in that area, I saw a squirrel go into a hole in an oak near post 41 in the campground.
