Protecting Yellowstone is the responsibility of the American public. Yellowstone is one of the most intact natural ecosystems in America, as is evidenced by the abundant wildlife which inhabits the Park. And although the large animals, such as the bison, elk, moose, grizzly and wolf generally get most of the attention, there are many more varieties of wildlife which inhabit the Yellowstone ecosystem, including many species of birds. One such bird, the trumpeter swan, is suddenly receiving a little more attention than usual. The wildlife group The Fund for Animals has submitted a petition calling for the U.S. Fish and Wildlife Service to declare Yellowstone's trumpeter swans endangered.
