Silver Teal

The Silver Teal (Anas versicolor) or Versicolor Teal is a species of dabbling duck in the genus Anas. It breeds in South America.

Between April and June they prefer reed beds and will lay 6 to 10 creamy-pink eggs. As with swans and geese, both parents will rear the ducklings.[citation needed] A pair may bond long term. It lives on fresh water in small groups, and feeds primarily on vegetable matter such as seeds and aquatic plants.[citation needed]

The Silver Teal's range includes southern Bolivia, southern Brazil, Paraguay, Argentina, Chile, Uruguay, South Georgia, South Sandwich Islands[1], and the Falkland Islands[2]. The southernmost birds migrate to southern Brazil in the winter.

Silver Teals are on the whole placid ducks but may be protective of eggs, young and females.[citation needed]

They have a black cap that extends below the eyes, and a bluish bill with a yellow tip. They also have a green speculum with a white border.[3]
The Puna Teal was previously regarded as a subspecies of this bird. Currently, there are two subspecies:

A. versicolor versicolor Northern Silver Teal located in Paraguay, southern Bolivia, and southern Brazil[2].
A. versicolor fretensis Southern Silver Teal located in southern Chile, Argentina, and the Falkland Islands[2].
