Chiloe Wigeon - Anas sibilatrix
The Chiloe Wigeon (Anas sibilatrix) is one of three species of wigeon in the dabbling duck genus Anas. Unlike other wigeons, the sexes are similar (though the male is often slightly brighter) and pairs are monogamous. This bird has a metallic green head, and a gray bill with a black tip. Its breast is barred black and white and its sides are orange brown. It has white cheeks and a white forehead and also white on its wings. Its length is approximately 50 cm.
The female lays between 6 and 10 eggs. This duck is unusual in the sense that the male helps to raise the young.
