The Confederated Salish and Kootenai Tribes successfully introduced Trumpeter Swans (Cygnus buccinators) into the Mission Valley in cooperation with the US Fish and Wildlife Service, Montana Fish, Wildlife and Parks and other entities. Nineteen swans were released at Pablo National Wildlife Refuge in 1996 and the swans are now established in the valley and breed yearly. Read about the details of the early success at this link.
