The trumpeter swan is a large waterfowl native to North America, known for its striking white plumage and long neck. It is the heaviest swan species, with adults weighing between 20 to 30 pounds. These swans are often found in lakes, rivers, and wetlands, where they feed on aquatic plants. Trumpeter swans are recognized for their distinctive, trumpeting call, which can be heard over long distances. They typically mate for life and are known to form strong family bonds. Conservation efforts have helped increase their population, as they were once endangered due to habitat loss and hunting.
