Wandering Whistling Duck
Dendrocygna arcuata
Formerly named tree ducks, the wandering whistling duck has its new name because of their loud whistling calls and the whistling noise their wings make during flight. They have long necks and legs and look like a cross between a goose and a duck. They have a strong head and neck with a darker crown and hindneck. The breast contains black spotting and the feathers are mostly dark brown. They range in size from 54–60 cm in height and weigh on average 750 grams. They mainly feed on grasses, waterlilies, water plants and occasionally insects and aquatic vertebrae.
