Trumpeter swans are found in Yellowstone throughout the year. In winter a moderate number of swans inhabit the Gibbon River in the area of Gibbon Meadows. Some of these swans stay the year round and breed in the same area. Some migrate back to Canada as the Canadian streams and lakes thaw every spring.
As is the case with most birdlife, swans are most active in early morning or late afternoon.
The Trumpeter Swan, is the largest native North American bird, if measured in terms of weight and length, and is (on average) the largest living waterfowl species on earth.
