About These Birds
Plumed Whistling-duck
A large whistling-duck with long buff flank plumes extending beyond the folded wings, brown body, pink bill, and upright posture. Endemic to Australia. Gregarious, forming large grazing flocks on grasslands near water. Feeds mainly on grasses and sedges rather than aquatic plants.
