Koford 26 Cynomys ludovicianus January 26, 1955 pushed now under edge strictly near leaf. I found some fine green grass leaves under Opuntia leaves (Bautler?), there the only apparent greener. They scratch 4-5X with forepaw, ultimately, then feed at spot—evidently digging for food (about 1"). (Two shot had green fragments in mouth. Stomach contents one shot their stomach were green too). I shot 3 in all kept them for examination. These were about 2' from burrow when shot with .22 hornet; they did not move more than a few inches & were unable to make strong attempt to get to burrow. This town mostly in SE 1/4 of Sec. 1 (R. 71 W.), overlapping 100 yds. E. into Sec. 6. Downstream colony limited by very rocky ground (scattered junipers; some yellow pine; a shrubby Quercus (?), near & between rocks). Colony on gentle slope, up to about 15% slope, an open ground. Many close to numerous rock outcrops of 10-15' height. Burrows reach N. to 200 yds. from crest of hill; why not to crest? Crest rockier than lower down soil probably thinner. Grass cover the very base of shot grasses with considerable spaces (to 6") between tufts. At some sites ground cracked. Red soil for most part with moderate gravel mixed. To W. a lower broader crest; a few burrows to W. of this but apparently not active. To E. & W. ground apparently suitable for spread, especially to W. where occasional bare spots in grass. I saw no rabbit but 1 set tracks in snow that appear
