We describe observations of black-tailed prairie dogs (Cynomys ludovicianus) emerging aboveground at night, apparently in response to wild-born and captive-born black-footed ferrets (Mustela nigripes) in South Dakota and New Mexico, respectively, We also discuss other similar observations accumulated on black-tailed prairie dog colonies as well as observations of white-tailed prairie dogs (Cynomys leucurus) making nighttime movements, apparently in response to pre-reintroduction ferrets in Wyoming. Our observations suggest that, in addition to documented daytime defenses against ferrets, prairie dogs reduce vulnerability to predation by ferrets by using evasive movements at night.
