Anas versicolor (Silver Teal)

Wikipedia Abstract

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. 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. Silver teals are on the whole placid ducks but may be protective of eggs, young and females.
