Koford 25 Cynomys ludovicianus January 25, 1955. Nr. Ft. Collins, Colo. Spermia close to burrows. One area apparently formerly part of colony had been ploughed. On black soil, a mound of red subsoil stood out strongly. Surface mounds looked crochded so apparently four rabbits. January 26, 1955. Talked with Milton "Pat" Ferree who lives 3 mi. NW of The Forbes (NW of Ft. Collins on road to Laramie). He had colony of about half a section, mostly in Sec. 1, T 10 N., R 71 W. He thought this colony an old one a spreading upthrust very drawn. He had possessed it with strychnine grain last year but without a good kill. Family lived in S. Col. Colorado (Kona & adj. co.) I said many Cynomys there but eliminated by 1080 poison (he talked as if he had personally used 1080 thus without Fish & Wildlife personnel). He + wife pleasant & friendly, the apparent- ly anti- S.C.S. I drove to the colony and saw C.L. out on mounds & running away in alarm. I saw up to 3 together at one burrow & as many as 5 set in one small group of burrows. I saw the first few upon arrival at 10:45 a.m. Only a few small patches snow left here. Some used burrow floors or lined with packed dirty snow. I set live traps baited with whole oats at 4 holes & steel traps at two when I saw C.L. go down burrow, (now captured by 2 p.m.). One pair alarmed by car so to top of burrow & one gave the straightening up display twice. Steel traps put inside burrow when 2 went down; but none caught. I watched one feed, pushing its nose under edge of "Lo Buckloe" loft (almost no stone left became close eating cabin) or grazing). Another
