The silver teal or versicolor teal (Spatula versicolor) is a species of dabbling duck in the genus Spatula. It breeds in South America.
Between April and June they prefer reed beds and will lay 6 to 10 creamy-pink eggs. The eggs will hatch after 25 to 27 days.[2] As with swans and geese, both parents will rear the ducklings.[3] 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.[4][citation needed][5]
The silver teal's range includes southern Bolivia, southern Brazil, Paraguay, Argentina, Chile, Uruguay, South Georgia, South Sandwich Islands,[1] and the Falkland Islands.[6] 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.[3]
Description
[edit]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.[7] The female's plumage is slightly duller and has less yellow at the base of the beak.[2]
The Puna teal was previously regarded as a subspecies of this bird. Currently, there are two subspecies:
- S. versicolor versicolor northern silver teal located in Paraguay, southern Bolivia, and southern Brazil.[6]
- S. versicolor fretensis southern silver teal located in southern Chile, Argentina, and the Falkland Islands.[6]
