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.
