Estimated Wild Population
The largest North American waterfowl, trumpeter swans have white plumage and a black bill. They feed primarily on seeds, grains, and wetland plants, as well as snails, insects, and small fish. These aquatic birds form breeding pairs at the age of 3 or 4, and pairs often mate for life. Female build a large grass nest near a body of water, where they lay four to six eggs. Upon hatching, offspring remain with their parents for three to four months before venturing off on their own.
