Koford Cynomys ludovicianus May 12, 1955. Wellington Larimer G, G10. about "not aired." Have seen 3 days ago. These animals fed much barley all winter. Breeding was apparently earlier here where much food than elsewhere. Also I note that a small g taken here, doubt- less a yearling, was pregnant. Good winter food = early breed- ing + high proportion yearling gg breeding ? May 13, 1955 Visited Wellington colony & saw 4 small young out at one burrow near "Charlie," as Crawford told me. Scanned area but found no other young out. Two Spotted in the area near Charlie. Perhaps 15 C.L./acre here, white fed, or even more. What will happen when young added? Saw 2 large houche (Buto ferry, prob.) over area. A marsh hawk chased one of them off. Perhaps the sanctuaries take C.L. - especially young ? Saw 3 Citellus 13- liometus in presence area. Very little Dalsola in presence. Due C.L.? But much Kochia (alkali tolerant). Several ant mounds present but not molested by C.L. Muhlenberg's torres, in large patches & apparently not held back by C.L. Little green grass present. Scratchings around some mouse of as if to build higher. Sky 8/10 overcast. Warm breezy. Left 10:30 q.m. Drove to: CPER, Weld G, G10. Looked over deer. 2 z colony. About 25 C.L. present, or more. Saw no juveniles. But 33' E. of stake 20W65 (red-pink) saw Cratetus at mouth of small burrow on flat ground. It was in sunshine. Fairly large. It could break into burrow when molested. Another tame C.L. in burrow 25 yds. distant. First Cratetus I have seen in C.L. town. || I shot an adult male on N. slope in E. part of colony, at water 50' S. of C.W.165. Stake. Teeter old,
