Koford 148 Cynomys ludovicianus June 29, 1955 Wind Cave Nat'l Park S. Dakota. distant, One C.l., 75 yds. away, stood atop 1½' tall stump, 6" diam., 75 yds. at ledges. Badgers seemed not to be hunting C.l. walked into prairie. I caught prairie dog in live trap at humourus where 5 juveniles seen yesterday (50's. of stake 1/3. area 95-96% favorable, but saw Amblyseius opuntiae, Potentilla. A dead. in steel trap in area Y, 100 yds. S. of Ward A, where juveniles taken yesterday. Pseudotsuga menziesii, Arctostaphylos uva-ursi, Brown's Creek, Festuca octoflora, Lappula, Astragalus bisulcatus, near site. In area Z, bottom, saw 3 grown + 4 juveniles. In cleft a female (mule deer) and another to an hole, a large one + 3 juveniles. To another juvenile, mauled & pulled out, who did not seem to mind. In the area where much background, digging 1 to 3" deep at lower Sphaerocarpos - shell of a digipede in hole (dig for larvae?). Near burrow their lawn + generally without brood, presumably due to C.l. activity. I visited eagle nest 200 yds. W. of W. and Shirttail town. Under it when sferement fell I found a neat ball of hair (saved for spore) + old C.l. shell. From cliff top pon seen interest; no food remains seen in it. One eaglet, nearly grown. Both parents flew when area viewed. In Ward A most C.l. (4) seen in region of stake 1/3 g/m, where it mounds large. Near there two groups pite about 4" deep, as old C.l. digging for plant. These in circular patches about 10' diam. + possibly formerly associated with thistle bars. Area W apparently unoccupied now. Fritillaria biflora + higher than near currently used burrows. I saw are eating tip 2" of cut Chenopodium (album ?-saved). At now, carrying tip 10', finally dropping it. A Chenop. (album-dele; saved), in Ward B some twigs cut in patches by C.l.
