Black-footed ferrets typically prey upon prairie dogs at night while prairie dogs
are presumably sleeping. Prairie dogs can act aggressively towards aboveground ferrets in
daylight and we observed prairie dog aggression towards ferrets four times in South Dakota
and Montana. Ten behaviors by prairie dogs were recorded during aggressive interactions
with ferrets including chasing, blocking, and physical contact. One of the aggressive prairie
dogs was confirmed as an adult male and three of four encounters occurred Jun. through Jul.
Interactions lasted 10 min and neither the prairie dog nor ferret were visibly injured. This phenomena was detailed in The American Midland Naturalist Journal in April 2013. Four video clips below show these interactions.
