About These Birds
Egyptian Goose
A large conspicuous sheldgoose-like bird with brown-and-white body, dark eye patches, a chestnut patch on the chest, and pink bill and legs. Native to Africa and the Nile Valley; widely introduced to Europe. Aggressive and territorial; found in urban parks. Feeds by grazing on grass.
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.
