Koford 76 Cynomys ludovicianus March 18, 1955 NW Weld Co., Colo. where little snow (but ground wet from melting), about 1% snow on colony. From W. end about 30 C.L. seen out. Clear & warm when nearly calm. At W. end to N. of fence, 4 at 1 hour, 4 just 85. of fence 20 yards, from there, 3 at 1 hour, No fresh snow of my closed traps by then two hours, one fed in shade of atrop. I watched me eat an 8" long stalk of green barked Elaeophyllum from base to tip, holding it in forepaws. Later 4 found several stalks set at sites & lying on ground: One of 4 went 30 yards, from rest 4 fed at 0 puncta. Two of 4 fed at one 0 puncta clump sometime, 4 1 of 3 on another clump. They scratch at leaf with dog-paddle motion, both forefoot (remove spines?) then bite & tug with teeth. Later shan showed freshly eaten segments green leaves 0 puncta there. One gathered dry grass in its mouth-probably Bouteloua gracilis. Nearly flat grounds of bottom to S. of streambed near center of colony seems found—at least 8 times at once. No green grass yet apparent on surface here. Badger not too active for a prairie dog corser I left in open on hilltop was still contended. I saw a hydriolagus in two burrows. On previous trip saw 1 in one of these same burrows. Parnelia might be eaten for scrape in burrow matches. At another site when scratching grounds seen were tiny scraps 0 puncta leaves & dead roots (possibly eat; white succulent); a detached broken leaf a few yards distant. I baited the 15 live traps & departed about 3:30 p.m. // At 4:45 at Spring Canyon Dam colony I saw more out 4 found now in traps: Tools set traps no. 4, 8, 11/2, 20, 4 23, & spring nest. Snow now gone from colony & occasional Blackgroun (?) a white & brown as well as several many grass near burrows. // Flies found on those collected.
