Spread and habitat
Duck spread in many areas of the world (Central and South America, Africa, India, Antilles Islands), especially in tropical areas. Sedentary, migratory or erratic depending on the localization area. It lives in open areas rich in stagnant waters but is also found along quiet bays and rivers.
Quiet, sociable and easy to breed species.
The two sexes are practically equal.
The head is brown with gray-white collar that starts from the chin strap. The neck, chest and belly are light brown. The sides have a white-brown barred area that fades into the undertail towards white. The upper part is black-brown with reddish scales towards the back and wings. Wings and tail tend to black. The legs and beak are light gray in color. Brown eyes.
Juveniles present a plumage similar to adults but with more muted and dull colors.
The size varies from 45 to 53 cm.
Nutrition and behavior
Active mainly at night. During the day she prefers to remain perched on a paw near the water. It adapts very well to life in captivity.
The diet is based on insects, seeds, molluscs and more which it procures by diving into the water.
It builds nests in the hollows of trees or in rocky ravines, where it lays 6-12 eggs. Male and female alternate at hatching for about 30 days. In captivity, artificial box nests are recommended.
