Journal Hafner, M.S. 1974 20 April 9.5 mi. N. Johannesburg, in "Copper-Colored" hill 1 mi. E of Trona Rd. San Bernardino Co. 3200' Caf. 20 April (cont) approx. 1.5 meters. The nest itself was about 2 m. wide by about 3 meters long and 2 ft deep. There were 3 main entrances visible and 2 shallow bird-nest-like indentations were on top of the nest about 2 meters apart - their function is unknown. This cave could be very interesting for future study of Neotoma during daylight conditions. Later in the P.M. we took a short walk noting a young fledgling house Finch and a Jackrabbit (Lepus). One of the nests (House Finch) that I had checked earlier now had 4 young and 1 egg instead of 1 young and 4 eggs as seen yesterday. A subed. Red-tailed Hawk was sighted in the late P.M. and a Zebra-tailed Lizard was kicked up in the sand, apparently too cold to flee. 1700 - We set traps near the small rock out cropping by the side of Trona Rd near the dirt road leading to Camp # 1.
