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.
Red Shoveler
A medium-sized shoveler with a distinctive spatula-shaped bill. Males are pale orange-brown with dark spots, grey-blue wing patch, and dark green speculum; females are mottled brown. Found across southern South America. Swims with bill tip in water, filtering zooplankton and seeds.
