Specimens examined (10).—2 mi. N, 5 mi. W Ludlow, 4; 1/2 mi. W Reva, 1; 4 mi. E Reva, 2; NW 1/4 sec. 32, R. 1 E, T. 20 N, 3.
The raccoon evidently is one of the commonest carnivores in Harding County. On June 24, 1961, a den with three young (average total length, 429) was found in one of the numerous pockets eroded from the caprock of the North Cave Hills, and on May 21, 1968, another den, this one containing five young (average total length of three, 271), was found in a similar situation on the east edge of the Long Pine Hills. A female trapped on June 20, 1961, was lactating.
Three individuals that had been killed at Ralph, along nearly treeless Big Nasty Creek, were examined on May 28, 1968.
Mustela frenata longicauda Bonaparte, 1838
Long-tailed Weasel
This mustelid seems uncommon in northwestern South Dakota. The only recent reports from Harding County that have come to our attention are of a female and four or five young that were found in a haystack "several years prior to 1963" (Robert Kriege, personal communication), and of several individuals seen by a rancher in a hay field along the Little Missouri about 7 mi. N Camp Crook during mowing operations in July 1970. Visher (1914:91) regarded the species as "quite common," and noted that "4 or 5 dead ones" were seen along roads in the summer of 1910.
Mustela nigripes (Audubon and Bachman, 1851)
Black-footed Ferret
In a recent summary of the natural history of this species in South Dakota, Henderson et al. (1969) listed seven localities in Harding County (all in prairie dog "towns") at which ferrets had been sighted or trapped as follows (dates in parentheses): near Ladner (March, 1963); 17 mi. N Camp Crook (about 1956 or 1957); T. 20 N, R. 3 E (1964); T. 20 N, R. 4 E (winter, 1964); T. 19 N, R. 1 E (late November, 1966); T. 17 N, R. 8 E (summer, 1965); T. 15 N, R. 1 E (winter, 1963). These authors also reported a specimen in the U.S. National Museum (no. 243990) that was taken at Govert on November 1, 1923. Additionally, Wesley Broer, then the local game warden, reported to one of our parties that a ferret was seen on February 27, 1963, at a place 7 mi. N and 16 mi. W Buffalo.
Visher (1914) made no mention of this species in his report of the natural history of Harding County.
