Chestnut Teal 

The Chestnut Teal (Anas castanea) is more often found in the estuarine, occasionally coastal areas, than most species of ducks. They feed by dabbling or up-ending, often grazing and also taking plant seeds and leaves as well as some insects and crustaceans. They are usually seen in small groups although larger flocks may congregate at times. They do not undertake extensive movements typical of the Grey Teal, preferring to remain where permanent water exists. They will use nest-boxes quite readily
