In this Friday, Sept. 23, 2011 photo, wildlife biologist Paul Marinari prepares to release a black-footed ferret into a prairie dog burrow in the Badlands National Park near Interior, S.D. The release of male ferret No. 7505 kicked off a weekend of ferret festivals nationwide to celebrate the 30th anniversary of the ferret's rediscovery in the wild. Conservationists say they hope to be able to remove the ferret from the endangered-species list by 2020. (AP Photo/Elijah Van Benschoten) less
