Rooford 45 Cynomys ludovicianus February 11, 1955 Mr. F.B. Collins, Colo. there were 4 or one mound close to fence & another 5' distant. Because of formerly active burrows of W. group, 3 on 1 mound. Two on one mound in SW groups. Some yelping seen & heard. Once I counted 16 total out at once. 7 in E.g.p., 2 in SW, & 11 in N. contact W. gps. (see back p. 33). Tried to walk close enough to shoot one but they allowed approach to only 15 yds. I examined troche in 3" deep snow. Apparently five or more mole yesterday. At one large fine shale mound where I saw one for long when attempted trapping, no troche at all. Food - within 50 yd. Diameter area were 4 spots where Opuntia leaf had been eaten & frag- ments & spines left on ground. Green tissue opposed of precise leaf 2-3 sq. inches detached. Chatted one of these. Another Opuntia leaf eaten, the yellow dried. At a certain W. group where I saw 3 at once, troche did not go to any other burrows. Largest series troche went 40 yds. from 1 burrow to another. Largest foraging trip from burrow about 15 yards. Salsole scraps at same troched spots when apparent feeding on branches (dry). Carcinin at same too but not eaten. Near pond bed where many rockchickens, some, opened as snow surface. Much Salsole too in pond bed. || Burrows (no.) counted by troche in groups of: 4 - 6 - 1 - 1 - 3 - 3 (in area where saw 5 or 6 out) - 2. No troche in SE groups. || Definitely 2 or more in some burrows. At one burrow troche of one went out only about 4', then returned to hole. Troches in herd showed visits to opposed ends sodar, thistle, cow-dung (the no sign eating), as if went to dark spot seeking food. || Troches - one kind in groups 610" 7 o o o → 7. Many troche showed clear scratch of 3 toes as feet brought forward [illegible] all widespreader. Photographed same troche in snow. I stood
