The Chiloe Wigeon breeds from central Chile and Argentina southwards. Southernmost populations migrate to Paraguay, Uruguay and south Brazil during the austral winter.

Chiloe Wigeon, Torres del Paine, Chile, December 2005 - click for larger image It is a very attractive duck with the male showing iridescent green on the back of the crown and neck. His face is largely white and there is a small white patch below the ear-coverts. The female is similar but duller with less white and iridescent green on the head. Both sexes have a smallish blue-grey bill with a black tip. The first photo shows a group of 3 males and 2 females.
