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.
European Robin
The European robin is one of the most beloved birds in Britain, where it is the unofficial national bird. Despite its friendly demeanor toward humans, robins are fiercely territorial against their own kind, singing year-round to defend territory. Their distinctive song is one of the first to be heard at dawn.
