Koford 1955 56 Cynomys ludovicianus February 25, 1955 Nr. Ft. Collins, Colo. out, last out having gone not over 3' from burrow. It then got caught in my steel trap there. I went & got it (0712). At first it tried to get down burrow, but when I close it struggled to get away. It bit at trap held near it. Crawled & pawed. // At site where 3 out in E. group, 3 or 4 burrows had tracks to them. Farthest distance tracks from a burrow was 15 yds. Some Xanthium burrs opened there, 4 many tracks to a clump of 3" high stub of grazed down Chrysothamnus bush. Several 1 1/2" long green barked stems 1/8" drain of C. cut off freshly. No greenery in grass there. Probably some eating at stubs of Buckle. No tracks from this group to other burrow in area (or N. of fence). I checked other traps; no activity. // At place where 2 out in W. groups (actually 50 yds. S. fence), tracks to 10 yds. from burrows. March fresh eating at 2 down of Opuntia (about 1 sq. inch eaten from each; this place I photographed). At site where we scratched, scratching was toward burrow as if to build sup mound but it did little effect in doing so. Again stubs + stolen Buckloe when some eating activity. Ground becoming muddy with melting snow. Departed 12:10 p.m. // Tracks of us running to burrow appeared: . . . . Distance forefoot to forefoot, 36"; foreft. to hind, 25". In extra long jumps, 30" space from foot we set tracker to next track . . . . // When 0711 put into chicken wire funnel & somewhat squeezed, it started series of alarm chirps - very loud indoors.
