Swans establish life-long mates at approximately 3 years of age.
Swans usually build their nests in March and early May.
It takes a Swan 2 weeks to build its nest.
Young Trumpeters are half their adult size and have feathers by the time they are 8 to 10 weeks.
The female Swan is called a Pen.
The trumpeter swan is a majestic bird, with snowy white feathers; jet-black bill, feet, and legs; and 8-foot wingspan. At close range, a thin orange-red line can be seen on the lower part of the bill. The trumpeter is often confused with the smaller, more northerly tundra swan, especially where their ranges overlap. The major differences between the two are their size, call, and migration.
The trumpeter swan is roughly twice the size of the tundra swan; has a deep, sonorous call; and is either non-migratory or migrates relatively short distances. The tundra swan weighs approximately 15 pounds, has a high whistling call, and migrates long distances between summer and winter ranges.
