Trumpeter Swans were first documented in Yellowstone National Park in the early 1900s, and they were common until the 1960s when their population started to decline. By 2010, there were only about 60 swans in the park. The loss of these birds has brought together more than seven different federal, state, and private agencies in the quest to bring them back to their former numbers.

Bald Eagles, Trumpeter Swan Numbers Up

This spring, the Wyoming Game and Fish Department reported an increase in bald eagle and trumpeter swan populations. Non-game Biologist Susan Patla conducted an aerial survey of the Jackson and Pinedale area last month to estimate the birds' populations.

Patla says the surveys showed that bald eagle numbers have grown stronger, even since they were removed from the Endangered Species List in 2007.

Wildlife interest groups and agencies in Wyoming and Idaho are working to increase the populations of trumpeter swans in the region. Loss of habitat has limited numbers within the species. The Teton Regional Land Trust is working with the Wyoming Wetland Society, local offices of US Fish and Wildlife Services, and the Idaho Fish and Game departments to build a nesting colony in Teton valley.
