About These Birds
Black Swan
The black swan was once considered impossible by Europeans who believed all swans were white, making it a famous philosophical example of inductive reasoning failure. It is the state emblem of Western Australia. Black swans form lifelong pair bonds and both parents share in incubation and care of cygnets.
Trumpeter Swan
North America's largest native waterfowl and one of the heaviest flying birds, with all-white plumage, a long neck, and all-black bill. Named for its resonant bugling call. Recovered from near extinction in the 20th century through active conservation. Breeds in northern wetlands.
