Black-Footed Ferrets on the prowl in Colorado

Black footed ferret (Mustela nigripes) listed as North America’s most endangered mammal by US Fish and Wildlife Service, is limping back from the brink in Colorado. A recent midnight survey had 10 sightings including a lactating female. Ferrets have been released in Colorado since 2001 as part of National reintroduction programme. The ferret population had plummeted following extensive use of fertilizers during 1920s and 30s and they were even considered extinct for some time.
