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.
Eurasian Magpie
The Eurasian magpie is one of the most intelligent animals on Earth and the first non-mammal demonstrated to recognize itself in a mirror. These bold corvids build elaborate domed nests of sticks and have a well-known attraction to shiny objects, though this reputation may be exaggerated.
