Species Profile
Did You Know?
The trumpeter swan is the world's largest member of the waterfowl family. Most Trumpeters weigh 21–30 pounds, although large males may exceed 35 pounds.
General Description
Like all swans, the sexes have identical plumage, and both tundra and trumpeter swan adults are all white. However, in some Alaska locales, iron-rich marshes stain head and neck feathers a rusty color. Feathers of immature swans are an ash gray color, and some gray feathers remain evident on the heads and necks of swans that are one and two years old. Trumpeter swans have an angular wedge-shaped head profile, with the black of the bill appearing to merge with the eye. Their bills are all black, with a red border on the mandible (lower jaw). One sure way to identify trumpeters is by their deep, French horn-like call, compared to the higher “whoop” of the tundra swan. Males average 28 pounds (12.7 kg) and females average 22 pounds (10.0 kg).
