Koford Cynomys ludovicianus February 5, 1955 Wind Cave N.P., S. Dakota slope (also in sun). Bare ground rather prominent on S. facing slope. C.b. dig a lot, then sit up & eat, holding food. Some food seemed to be bones of grasses, dry at tips. I shot one of that was near two burrows in snow. There were 4 scratched out holes, about 2" deep, in reddish soil with 1/8" icy snow cover. Apparently nests uncovered & eaten. 3:15, only 1 cut on N. slope (10%), 7 on S. slope (5-10%). One fed & gave tiritual yelps (straight line pitch & body) within 50 yds. of my parked car. It was neat, feisty, when gave yelps, I did not drop down from erect paw afterwards. || I spent 3/4 hour walking around in Bintail Canyon Town & saw not one C.b. Somehow protected from wind this a some S. slope, but none seen, among trees. Many burrows here near (30 yds. far) pine trees. || 3:20, shadows long on N. slope & wind about 20 mph. Now out on N. slope & only 5 on S. slope. Dogs wary; I could not drive to closer than about 75 yds. I drove down draw (E.) about 300 yds. to old earth dam about 4' high & 200' long. Here said to be oldest part of town. Mounds especially large & widely spaced, it appeared. Some about 1/2' high & 5 yds. across. All mound-like, not distinct. Large mounds may mean old (or loose soil?). No C.b. out by 4p.m. Their day apparently about 5 hrs. long today, & doubtless many not out at all. || As its former grazing by buffalo or park, Dengerin said that once there were 550 when park less than half present size. NW part was formerly part of Nobek Wildlife Refuge. Now aim at 350 bison but have permission to cut this to about 100 if necessary to maintain range. || Schiffer (V.B.) heard C.b. on Sec. 22 Town near CPER on Aug. 24, 1954. 40 rat traps, previously listed, took now by 6 p.m. 42
