Koford 67 Cynomys ludovicianus March 8, 1955 Nw. Nunn, Colorado Saw 1 N. of fence at west end colony. Two active burrows thin, 35-70 yds., N. of fence about 50 yds. west of stream. Two shallow old burrows 30 yds. N. of those. None to E. of streamed N. of fence. Opuntia shows heavy use. Half of small clumps eaten or broken off freshly, some whole leave broken off at ground level. Within 15 yds. 1 burrow, 7 clumps Opuntia show use. 4-6 show no obvious use. Throughout colony similar eating opuntia. Skin of leaves still grown in despite zero temps. during winter. Some fragments in bur raw months, 4 Parmelia too (brought in?). No digging for roots in this colony (much at Spring Canyon Dam) the shallow scratching among Opuntia clumps, 1/3 on flat ground, floodplain of stream, many sunken areas about 2 ft. in depth with 4-6 foot deep with burrow leaking off from bottom - no mounds; may be cottontails. One had cut Salsola at mouth as if used for nesting material. Daucus sylvestris crushed in mouth of a crater 20 yds. from a mound with a C.L., rabbit went down hole about 2 hrs. later rabbit seen at mouth some burrow. Saw 1 grasshopper nymph. At top eagle level found many old remains Lepus but no Cynomys. Then I found 4 other fresh eagle casts (saved; these remains collected in Doc.). Saw 1 eagle 1/2 mile distant while at colony. 1/3 active burrows 2 yds. apart apparently bored out by badger last year. I picked up Lepus (Cervis?) droppings at 3 sites near burrows (saved). At least end colony I found three active burrows (C.L. seen or heard at two). These were 50
