Koford Cynomys ludovicianus S. Dakota. February 2, 1955. Wind Cave National Park, recertivarin (Dute says), I saw half a dozen lodges bored out holes in short examination. 1/4 mile W. of town were two old eagle nests on red limestone cliffs. I found no casts or bones below, but difficult in snow. No eagles seen. /The Bison Flats town said to be more recent, 4 increasing. Most of it on rolling grassland (Shorttail camply because of criffs, stream, trees). Old part Bison Flats town to SE, near a dam, said E. Dute. /Naloch Dam town shows great de- struction & crashing of rail near road. I think this due to heavy ice by lice (many droppings). About 10 a.m., in fog, 4 1" snow on ground, I saw tracks of as far as 50 yards from burrows (one to another), but only 2 sets of tracks in about 200 yards of walking. (Saw a few out on Bison Flats town but none on Shorttail (remote from pavement visitors)). Town No. 3 on Sec. 31-36 line (1½ E. of Naloch Dam) said to have been poisoned. Two Badger droppings with C.L. nest of fine grass atop ground. conspicuous war pigeon about 18" high in line in this town. We visited town in Dec. 22 (R.6E, T.53), which had been poisoned a area recorded. This in red soil area showing some heavy erosion. Fence taken down 1954 - had enclosed a soil & moisture experimental plot in town. F.B. (Picked up coyote scat in town No. 3; saw 2 coyotes walk across Naloch Dam town). Few Crotalus in Wind Cave Ph. but many at Badlands D.M., said Dute (found Sept. at Bad- lands). /Prarie dog poisoning due has been carried on since 1952, August, with strychnine poisoned oats.
