About These Birds
Taiga Bean Goose
A large brown goose with dark head and neck, orange-and-black bill, and orange legs. One of two bean goose species. Breeds in Scandinavian and Russian taiga; winters in western and central Europe. Recognized as separate from Tundra Bean Goose since 2007.
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.
