Anas versicolor - MHNT

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.[2] 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.[3][4]

The silver teal's range includes southern Bolivia, southern Brazil, Paraguay, Argentina, Chile, Uruguay, South Georgia, South Sandwich Islands,[1] and the Falkland Islands.[5] 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.[2]

Description

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.[6]

The Puna teal was previously regarded as a subspecies of this bird. Currently, there are two subspecies:
