The Trumpeter Swan is huge and weighs more than any other North American native bird. Once endangered, it is now doing well in the northwest. It is also doing well after being introduced in northern plains and the Great Lakes region.
Similar to the Tundra Swan, the Trumpeter is larger (8" longer) with a massive all-black bill. In summer, the Trumpeter is mostly further south than the Tundra, but the two overlap in migration and winter. The size difference in noticeable when the two species are side-by-side.
National Geographic's Field Guide says the the Trumpeter's range is in the Great Lakes and upper mid-west regions, and adds that a few individuals wander south in winter to the mid-south and mid-Atlantic regions, and sometimes even farther.
Trumpeter Swans are especially noticeable for their loud, deep voices.
