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.
Northern Shoveler
A medium-sized duck with a dramatically large spatula-shaped bill perfectly adapted for filter-feeding. Males have an iridescent green head, white breast, chestnut flanks, and sky-blue wing patches. Highly migratory; one of the Northern Hemisphere's most widespread ducks.
