Koford pitch with water drywall dale Cynomys ludovicianus Fence → W May 31, 1955 Nr. Ft. Collins, Colo. 5, 5 (spread 10yds.; same?). There in area about 150 yds. lug 70yds. (2A±). One or more who near each little litter. Young lay on bellierion mounds, pestured adults, fed. Spread widely (10± yds.). but gathered at one (a r) burrow in alarm, allow approach to about 30yds. Juns, give jump up & down. All there on N. slope between irrigation ditch + fence (max. 70 yds. distant) an est. 5% slope, at mid slope or higher. One burrow appear. Bodge dug as large hole, but 4 juns. entred. Another 1'wide hole, possibly from erosion; juns. entered. One crotta where juns. showed scratching toward hole all around. At least 4 litters I have seen so far seen so far sure 2 holes, about 5 yds. apart, one a crotta & one a rounded mound (probably underground connection). || On Dec. 4, fall plants what field being ploughed up today. What will be effect on Jovan or + C.L. that fed this (same many burrows too), || About 4 p.m. visited Dec. 4 colony. On the unploughed bottom near S. side I saw litters of 2, 6, 47 juns., in a line 150 yds. long; 50 to W. from the 7, a group of 9, + 50 - 100 yds. from that one group, Ladley litter of 2 + 5. Saw a few C.L. at burrows in wheat field on S. side, but only one litter - of 5, on flatish ground. On unploughed ground 10 yds. above edge of this field, another litter of 5. || Not easy to trap juns. They did not eat grain or carrot bait put out in live traps near burrows. Set steel trap one hole where 4 saw; in 4 hrs. no apparent activity there, but the 4 out a hole 5 yds. distant. Put live trap directly in front hole where 4 went in; no catch in 4 hrs. Took up all traps. Saw one Swainson hawk near colony.
