Anas gracilis (Grey Teal)

Wikipedia Abstract

The grey teal (Anas gracilis) is a dabbling duck found in open wetlands in Australia and New Zealand. This is a mottled brown duck with white and green flashes on its wings. The male and female grey teal share the same colouration, in contrast to the related chestnut teal, whose male and female are strikingly different. The grey teal has almost identical colouration to the female chestnut teal and the Grey can only be distinguished by its lighter coloured neck and paler face. Juveniles are paler than adults, especially on the head.
