The chestnut teal (Anas castanea) is a dabbling duck found in southern Australia. It is protected under the National Parks and Wildlife Act 1974.
The chestnut teal is darker and a slightly bigger bird than the grey teal.
The male has a distinctive green coloured head and mottled brown body. The female has a brown head and mottled brown body. The female is almost identical in appearance to the grey teal.
The female chestnut teal has a loud penetrating "laughing" quack repeated rapidly nine times or more.
Chestnut teals form monogamous pairs that stay together outside the breeding season, defend the nest site and look after the young when hatched. Nests are usually located over water, in a down-lined tree hollow abo
