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.
Mallard
The mallard is the ancestor of most domestic duck breeds and the most abundant and widespread dabbling duck in the world. Males perform elaborate courtship displays including head-bobbing and whistle-grunt calls. Mallards are highly adaptable, thriving in both wilderness and urban environments.
