Koford, R. 1925 Journal Segolen Creek Field station, #6400 ft., 8 mi. NW Hobart Mills, Nevada Co., Calif. 17 October on the floor of the valley. I heard chirping calls from chickarees at 1530, 1600, and 1625, and 1922. Steve Thompson and I saw a gray deer - apparently a buck, with a completely broken femur - the leg left rear leg not dangling - which went slowly away from us.

We then went # of tag 89 and picked up the woodrat traps - all empty. I had picked up my only trap at that site last night. Steve Thompson released the buck he'd caught last night. I kept the female alive at the field station until around midday, when I put it up (#46) There were signs of recent activity - new yellow urine on a whitewashed rock - made since yesterday afternoon, but these
