Koford, 16 1977 Journal White Cloud campground, 4300 ft, 11 mi. E Nevada City (by car), Nevada Co., Calif. 16 Aug. I arrived in the evening, watched a nest of recently weaned juvenes. I spent the last few days in the Insitute Meadows area of Yocemite National Park. Squirrel density there seemed very low - less than 1/ha. I only heard about 5 chirps on an average day. Mostly Lodgepoles - not a good cone year, but I found several old pecked areas, a few newly eaten cones.

Here, sky clean except for a heavy haze low in the west, making the light disappear prematurely from the treetops. Wind light, temp. 74°F at 2030. I saw a sq. carrying nest material. 17 Aug. I spent 0555 - 1225, 1550 - 1905, 1920 - 2015 in the 1st study area, watching a nest in the morning, a former nest in the evening. 6 traps were set by 0725, closed ~1815. I removed chipmunks 6 times. I saw a sq. carrying nest material to its hole, saw a chase with buzzing, heard another. I clickerace ignored a Gray Sq, another chased one. I saw 4 Gray Squirrels, 2 in the study area, 2 in the campground. I also saw several chipmunks. Wind light, skys - 97% cloudy in the early morning, overcast by midmorning and it remained so for the rest of the day. Apparently it rained in southern Calh. Temp. 72° at 0550, 80° at 1400, 70° at 2020. 18 Aug. I spent 0640 - 1303, 1445 - 1715 in the 1st study area, plus a while in the evening looking for sq. E's juvenes.
