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.
Mute Swan
The mute swan is one of the heaviest flying birds, with males weighing up to 14 kg. Despite its name, it is not truly mute, producing hissing, grunting, and snorting sounds. Mute swans form lifelong pair bonds and their aggressive defense of nesting territory is well known.
