Koford 49 Cynomys ludovicianus February 15, 1955 Larimer Co., Colo. about 2. drouy lining for first 2 feet on snow. Finally get 3 (by 12:30 p.m.). #3 stayed out, went to other burrow, + fed after 2 others went down hole when groups planned. This one a min. q. #2 taken as follows. I saw 1 on mound & stopped 100 yds. distant. It froze for 5 min., then starts flicking tail forward, & soon starts to froge. A seems ran up to it. They ( same? ) nod, then one smelled near other. Doors are smelled near other. I shot the one farthest from burrow; min. q. #1 was appar- ently unaccompanied & shot at 150 yds. An older q. Probably shot 25 wide seen in all. One gave alarm (?) call at rate 3/sec. Probably only some fraction of total out. By 12 M. 9/10 cu.-str. clouds & 30 mph. wind. Increasingly cloudy. Debated 2 p.m.; a few still out there. // At Spring Canyon Dam colony found 1 steel trap sprung & one with ad. or caught by foxfoot (trap set yesterday). This #8. It had not tried to grow leg but was facing down burrow, pulling. Very muddy & apparently cold & tired. Took all 4 to C.S. A&M., Zoöl. Dept. // No sure evidence new burrows or appearance colony yet. Little or no evidence current repair of burrows. Feb. 16, 1955. Nr. Ft. Collins, Colo. Clean day, warm (55°F?), of mod. breeze. At 1 p.m. visited Spring Canyon Dam colony. Only about ½4 grown snow covers. Saw 9 out at once. Two ( #7 & #10 ) adult males taken at burrows 5 yds. apart in W. groups. (One killed for sperm- ortion; #7.0 leptolim). One of these on trap outside burrow. It lay flat a belly & froze as I approached. Then it growled & snarled loudly & lunged at me with open mouth again again. The other, a short distance down burrow, made no sound,
