Appearance:

May only be confused with Egyptian Goose, but differs in short, dark legs, dark bill, thicker neck, rufous belly and lack of eye-patch. Black and white wings conspicuous in flight as in Egyptian Goose, but lacks thin, black stripe at rear of white coverts. Sexes quite similar. Male with ringed neck in breeding plumage, and female with more contrasting facial pattern. Immature similar to female, but with "dirty" white wing-patches. Less dependent on water than most other ducks.

Sound:

Distinct voice and quite vocal. Nasal, trumpeting, donkey-like calls, often drawn out to a rattling, trill (Chewbacca of Star Wars). Male higher pitched than female.

Appearance:

A very large, long and slender bird. Bigger than Grey Heron. Plumage grey, with contrasting black throat and flight-feathers. White sides of neck. Tertials forms fluffed, ostrich-like rear end. Red crown visible at close range. Easily told from herons in flight by the straight neck. Juveniles with rufous head, lacking the marked pattern of adults.

Sound:

Powerful, resonant and bugling "kriiiiioooo" in various forms. Very far reaching. Often heard in duet where the female immediately answers the male call at a slightly deeper pitch. Also very vocal when flocks meet.
