Koford 21 Cynomys ludovicianus January 19, 1955 Larimer Co., Colo. about 2 miles before road reaches The Forks. Prominent colony sec. 31, 5 mi. SW of Lake Loveland. Two (NW one not traced) 2 mi. SW of Lauter's Reservoir near Loveland. As to variety of said 4 maintain, some in fairly rocky ground where lobola [illegible] (last mentioned?). One in bottom slough (1 mi. NW of Boeschen Lake). In all Minin told me of about 30 towns of varying size, largest covering perhaps 1/4 acre. About half towns were obviously near a stream, lake, reservoir, a drainage ditch, indicating some competition with maintain (a certain stage in vegetation?). Minin also noted C. l. not on top of ridges. He said that many 1080 pawns on rolled oats, few C. l. die above grounds. With shooting too, few meet get down burrows. Impoisoning every burrow treated, yet, twelve days later, remaining C. l. all in one patrol colony (gathering together of scattered wide?). Some seem to scrape pawns usually. (Crowe has not longer experience so should know more about this). Mounds at Tony Ramon place especially large (2 mi. E. of Round Butte in T 11 N, R 68 W. Minin very cooperative & pleasant. He is wildlife student at Colo. A&M. He said he has seen no ferrets, not many C. l. holes that have been dug into by lodgers. / Deporter said they repair mounds some after road scraper scrapes it away. But he says they move out when land ploughed in area around, due to lack of food. / Minin said one colony near alfalfa. Cut crops in edge alfalfa but did not burrow in the alfalfa.
