Koford 304 Cynomys ludovicianus October 16, 1955 N. of Waverly, Larimer Co. 11. No catch in 15 snap traps left same sites as yesterday. One still trap held jiv. Sylviolique. Not saw sites 1" big turf had been heavily eaten at edge, blades torn up, evidently by C.L. Crotta in seed now, shelling harder, but saw evidence eating by C.L. October 17, 1955. Took up still traps at Sec. 10. No C.L. taken, but one jiv. Sylviolique (this + one yesterday eaten lummus with water mound freshly built, only 3" high), both very young jives. (A Sylv. taken at Sec. 13 at C.L. burrow about Oct. 12 too). Today clear, dry, mod. N. breeze. At Sec. 10, 11 Antilocapra on colony area. 11 On Sec. 10, Bda eaten over area 1-2 sq.ft. at same sites. Bgrs eaten at many sites. Burrow in hardwort, eating mostly at edges, with scratchings there. Bda saw alone bottom, but Bgr common. Bgrs highest 70 component atop low ridge, but fewest C.L. there (ft. slope preferred). Bgrs now taller, greener, then Bda, which is thin, dry. 11 At large crotta where we trapped 4-5 apparent jives. Seen and dogs ago, many traps on seen (no sign) since. Disturbance of trapping probably caused abandonment. None of about 10 other traps on weed appearing wounds sprung since yesterday noon (to 11 a.m. today). Arm green & blades 4" tall on some clearings around burrows, but not cut (no seedstalks present). 11 Mullenburg co apparently not eaten though green & adjacent interspersed patcher Bgrs eaten. Much greener here than turns seen last month in N. Dakota & NW S. Dakota. No digging for food noted at Sec. 10. C.L. very here & rarely seen within:
