About These Birds
Musk Duck
Australia's largest stiff-tailed duck (~1.9 kg), family Anatidae, males bearing a leathery lobe pendant from the bill. Inhabits deep permanent freshwater lakes and swamps in southern Australia. Males emit a musky odor during courtship displays. Dives for fish, frogs, crustaceans, and mollusks. Least Concern; solitary and rarely seen due to secretive behavior.
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.
