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.
Whooper Swan
A large all-white swan with a long neck and a distinctive yellow-and-black bill pattern—a large yellow wedge extending to the nostrils. The national bird of Finland. Calls with a bugling whooping resonance. Breeds in Eurasian subarctic; winters in northwest Europe and East Asia.
