Dean E. Biggins Lou Hanebury Courtney Conway Chris Wemmer Brian Miller 1991 <p>Black-footed ferrets (<i>Mustela nigripes</i>) are an endangered carnivore endemic to North America. &nbsp;This small nocturnal member of the weasel family is totally dependent on the prairie dog (<i>Cynomys</i> spp.) ecosystem for survival. &nbsp;The ferret lives in prairie dog burrows and relies on prairie dogs for 90 percent of its diet (3,21). &nbsp;Poisoning of prairie dogs was largely responsible for the 98 percent reduction in geographic distribution of prairie dogs; concurrently, black-footed ferret numbers plummeted. &nbsp;Recently, only a single known population of black-footed ferrets remained. &nbsp;In 1985 that popuation, located near Meeteetse Wyoming, succumbed to an outbreak of canine distemper, and the few remaining ferrets were taken into captivity in an attempt to save the species through captive progation.</p> application/pdf en Wildlife Rehabilitation Association Rehabilitation of a Species: The Black-Footed Ferret (Mustela nigripes) text
