About These Birds
Madagascar Teal
A small brown teal with fine spotted plumage, red eye, and blue-green speculum. Endemic to Madagascar. Endangered; restricted to mangroves, coastal wetlands, and freshwater areas of western Madagascar. Threatened by habitat destruction and hunting.
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.
