National Geographic - American Cougar (2012)
American Cougar tells a unique story of a community of cougars whose skills are illustrated and tested as they struggle to survive in the severe landscape of the Northern Rocky Mountains. A determined team of researchers, lead by houndsman and researcher Boone Smith, mount grueling expeditions in attempts to gain precious scientific data. The story features F51, a young crafty female who makes her way through the winter, but is tested as she struggles to bring her unborn litter to a healthy birth after a cruel winter. The matron, wise F109, carries the key to crucial scientific data, but she’s a ghost, and a true master of escape.
