Koford 327 Cynomys ludovicianus December 16, 1955 darmier & weld Gos, Colo. Strong warm wind melted much snow today. At Wellington presence saw no C.L., but a Sylvilgug in one of my 3 steel traps; or me at mouth of C.L. burrow. At CPER too I saw none + none in 3 steel traps, nor any sign activity since traps set yesterday. Wind inhibit activity? Much warmer (20° ma) this afternoon than yesterday p.m. || Yesterday several C.L. burrows at CPER had snow plugs but small hole as if mouse had entered. Some Several had frosty- edged opening, showing no immediate use but possibly animal respiring within. I saw 1 Buteo near Wellington presence, but none, no eagles, no carnivore tracks, at (CPER colony (Dec. 22). Nr. Wellington, Larimer Co., Colo. December 18, 1955 Left 3 steel traps set (see above) in Wellington presence. This afternoon oversprang, with Sylvilgug foot, 1 gone (wire broke). Took up broken traps. Some at C.L. outdoor lodger Nr. Ft. Collins, Colo. December 20, 1955 About 2 p.m. visited Spring Canyon Dam colony. Warm, calm, snow melting fast, but sections of ground still covered with snow. I saw at least 12 out, apparently feeding, not seen 2 near at any site. No shrinkage colony extent, as fresh tracks at 5. optiminity of summer optimum. Made overlay maps showing locations where dogs seen. Many burrows open, or if by cottontails, I saw 1 Sylvilgug at mouth burrow; it now in. Still a fair cover of Buckwheat, grown at base. No digging found. In one burrow found 2-3" long section Shag stem. I set 10 steel traps, buried, at months burrows. Probably none out today after I left.
