In this undated photo provided by the National Park Service, researcher Scott Horton slowly climbs a tree while searching for a fisher den in the Olympic National Park, Wash. Horton was unsure which hole the den was in, so he slowly climbed the tree and stuck a camera in each hole to take a photo, finally confirming a den when the kits growled back at his camera. Wildlife officials reintroduced 90 fishers to the Olympic peninsula a few years ago, and are now preparing a plan to possibly reintroduce more of the cat-sized, forest-dwelling carnivores to Mount Rainier and North Cascades national parks as early as 2015. The fishers, which feed on small mammals, including snowshoe hares, mountain beavers and porcupines, have been missing from the region since the mid-90s. (AP Photo/National Park Service)
