Koford, R. 1975 Journal White Cloud campground 11 mi. E Nevada City, Nevada Co., Calif. 4200 ft. 8 April seen. The distance between the tracks varied from 10 cm. to 14 cm., and usually the tail mark was not visible (it was when the animal was going downhill, sometimes). → Birds seen (no sp. accounts) 3 Steller Jays 6 Golden-crowned Kinglets 2 Red-breasted Nuthatches 2 White-headed Woodpeckers 1 Downy Woodpecker (?) 1 Brown Creeper 9 April I set 6 Tomahawk noncollapsible traps in the area to the south of the slanted oak - baited with peanuts.
