The elusive white-winged duck (Asarcornis Scutulata) is a large tropical forest species from South East Asia. The male and female are similar, having freckled white heads and necks with dark bodies, contrasting with striking white forewings. Notably, females are smaller, with heavier freckling on their heads. It is found in shallow pools and marshes in the lowland tropical forests of India (Northeastern states), Bhutan, Bangladesh, Myanmar, Thailand, Laos, Cambodia, Vietnam and Indonesia. It nests in tree hollows close to water.
