Koford, R. 1975 Journal White Cloud campground 4300 ft., 11 mi E Nevada City (by rd.), Nevada Co, Calif. 27 May I got 4 lb. dry ice in Nevada City, drove to the campground, and parked north of the 29.30 mile marker. I opened the traps and stayed in the campground and study area, mostly the latter, from 0830 to 1330 and 1600 to 2000, hearing several churring calls and seeing at least 4 squirrels. Ponderosa Pine male cones are being eaten by the chickarees, as are the new shoots of the Black Oaks. I haven't seen any fresh Douglas Fir male cone-bearing twig tips lately. The squirrel tail by stake A4 is shorter and in 2 pieces now. The Douglas Fir buds are opening, the Manzanita flowers are out, as are those of the Geomothus prostratus. I saw 1 Gray Squirrel and a ? Flicker and found a Robin nest with 3 eggs. Sky was clear, wind mostly light but gusts up to 15 or 20 mph. Temp. at 0830 was 57°F; at 1600 it was 71°F, and at 2000 it was 59°F. 28 May I walked around the campground and study area, mostly the latter, from 0800 to 1300 and from 1500 to 2000. I heard several churring calls, probably all made by the same squirrel. There are only a few camping spots occupied, as there were yesterday. New bird - Warbling Vireo. Temp. at 0800 was 56°F; at 1500 it was 74°F, and at 2000 it was 66°F. Sky clear in the morning, 10-20% light clouds around midday, then clear in the afternoon. It was windy - mostly 10-20mph. 5 June I arrived at 1500 and set out 15 traps in the eastern part of the study area, recapturing 1 squirrel. I heard no churring calls or alarm calls. I stayed in the study area until 2015. There are many male oak flowers on the
