Koford Cynomyx ludovicianus January 39 1955 Na.Ft. Collins, Colo. C.L.s paid no atten. cars passing on highway 150 yds. distant. One on a mound since morning; I put traps there 2 p.m. & quickly left. The C.L. (as nearly other) ran 20 yds. toward me 4 down hole (not both down, hole). Shoe-I watched from distant point 200' above level colony 4 to W. about 2:20 at least 4 still out in E. group (had not been alarmed by my setting traps). Then in 10 yds. dean. me on park bed near edge. Two seen to go down same burrow. One seen to run about 60 yps. (from park bed) to go down burrow. An airplane passing 2000' overhead (noisy) seemed to cause some alarm (to far to hear calls). 2:45-2 2:45] flew out. F.t.e. saw 1 out in E. group (prototype). Calm but darkening. Light from north with 420 p. photo eff. meter. 2:55, 4 out in E. gp., 2 in S.W. g.p.; 6 total. None out in N.E. gp. Apparently some have re- tired for the day.

Park bottom has much vegetation, apparently different from higher ground. Another coper (= dump col.; some dogs) with definite colony of 40 Ariege deer 1/4 mile E. of this one in a creek draw. 3:25, 6 out in E. gp., 2 in S.W. g.p. None seen in N. center grp. since I arrived this morning tho I set no traps there 4 did not work through it. 3:45, two out in E. gp. One now alone by other. (one shed staked in snow). walked down burrow. Other followed down. One of S.W. g.p. out 3:45. Cimmer (cim.-tris.) concert, calm, 5½°C. Now only a few patches snow left. At 4:15 more out; ran at 4:30 when sky cleared our sun shut sun set in E. gp. I took up tapes. No wholecoat bait near holes taken. Apparently, trap presence keeps in burrows. I found an area of
