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.

A small dark teal with blue-grey bill and legs, brown-streaked plumage, and fine pale spotting on the flanks. The most widespread teal in sub-Saharan Africa. Found on freshwater lakes and marshes. Highly nomadic; follows seasonal rainfall. Swims low in the water like a pochard.
