Roford 30 Cynomys ludovicianus January 20,1955 Nr. Loveland, Larimer Co., Colo. burrows & live in the ploughed field? (also smaller burrow was or of beaump in ploughed ground). At about 12:30 I saw 11 C.l. out. Down stop mounds (2 rows), some foraging & running. The active part of colony in an open stand of Atriplex canescens. Bushes to 4' high. Some burrows against these bushes & bushes not cut down. Apparently no recent cattle grazing on this 40 as some grama stolth 12" tall. I took 2 photos this area. Some mounds large. About 5 of perhaps 50 had been dug into by badgers. Mound scattered & hole bore about 12" diameter. I found no badger scats. Two burrows went down alongside fenceposts so as to make post loose. Several were in the mounds (8-10" high, 1½' wide; covered with down local part of tough grasses, about 3" tall) that seem to form under wet conditions. Why in these mounds? At S. edge colony old burrows in area that had apparently been circulated for ground & burrow win salt crusts. It seems that C.l. get as close to water as possible without getting too close for burrows to be flooded! Check this. Advantage of wetness is green veg- etation. All around this part of town was a belt of 100 to 200 yards of inactive burrows (recent poison?). About 150 yds. to W. was unsettled but this stand of Bantelove grasses with old burrows near. 3/8 mile S. of colony & at 10' lower
