Koford 1955 Cynomys ludovicianus February 24, 1955. Nr. Ft. Collins, Colo. up a morsel, sits up on branches, 4 sets, holding food with both forepaws. Walks about 3 steps/sec., with forefoot, or slower. Then finds another toillet. Wandering about within 5 yds., burrow, foraging. Still at it 9:20 when light breeze comes up. Another out 9:20, this one in th E. group, N. edge. It keeps forefoot on a dark object & puts more down to feed for about 1 second at at time. Looks up every 1-1/2 sec. Very alert. No others out by 9:25. Temperature air 2' above ground in open shade = -8° C. (= 17½°F.). Breeze est. 5 m.p.h. from S.E. 9:30, a third out, 100 yds. S. of fence. Then another with the second, 4 at 4:38 a third out of burrow where the two are out in E. gps. N. offence. One of these gave a "jump up". They go up onto hind feet & then head muzzle up vertically, then quickly drop down. Three feed peacefully around one mound, #3 apparently went back in as not seen again by 9:45. Still only the 4 out 9:50. The group of 3, about same size & could be jovs. Occas. one seems with loping gate, belly in upward curve throughout, not straightening trunk in jumps.
