Siberian polecats (Mustela eversmanni) were placed in white-tailed prairie dog (Cynomys leucurus) and black-tailed prairie dog (C. ludovicianus) burrows to simulate a black-footed ferret (M. nigripes) visit. Both prairie dog species plugged burrows "visited" by polecats. White-tailed and black-tailed prairie dogs plugged 2 of 6 and 3 of 6 test burrows, respectively.
