The silver teal or versicolor teal (Anas versicolor) 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]
