Koford 328 Cynomys ludovicianus December 23, 1955 Nr. Wellington, N.Glo. is important. Several sacks of grain had been dumped in main part of colony (within last few days), but no sign of C.L. eating yet. Nr. Ft. Gilling, Glo. December 25, 1955. Checked Spring Canyon Dam colony traps. No catch. Took up 2 traps, leaving 13. Warm- calm today - more pleasant weather since early Nov. At this colony most mounds + burrows cover area 3' in diam, the same mounds 6' across. Bare area about 6' diam, + half bare area 10'. In some areas where rock scree tilted out, hundreds of fine roots protrude out of low soil 4' upward, haulike. Nr. Wellington, Glo. December 26, 1955. Another warm calm day, but 1/2 overcast. Temp. probably over 60° midday. At Wellington present colony at 10:30 a.m. I saw 4 out in census area, whom not seen since October; 3 at 1 p.m. Appears small, jowl. Then drove to CPER Dec. 22, colony, Weld Co. Saw about 25 dogs out, throughout colony. Seen seen in peripheral appearance areas, excludes such as the S. one, 4 fresh signs of ground repair at center near , at north end of expansion. So, no retraction into old part of colony from areas new expansion. One eagle perched atop hill 1/4 mile N of colony (I picked up a large cast then), + another seen flying 1/4 mile distant. / I shot a small ? near 20 W 10 S at about 11 a.m. This near edge of S. expansion. Some Bgn. Daces still green. Shot a large ? near 20 W 4 S (07/193). No dogs or sign to E. offance - so stopping out in summer keeps out for rest of year, perhaps until late spring. Russian thistle
