Anas gracilis is a small Australasian dabbling duck common in New Zealand. It differs from female mallards and grey ducks through its smaller size, pale throat and bright crimson eye. The plumage is finely mottled grey-brown, with a rounded forehead and dark bill. A green-and-white wing panel is visible in flight.
It occurs throughout New Zealand on shallow fresh and brackish waters. Numbers can increase after birds disperse from drought-affected Australia. It dabbles for seeds and aquatic invertebrates in shallow water. Flocks often rest tightly together by day and feed toward evening.
The New Zealand classification is Not Threatened. Lake Ellesmere Te Waihora and Miranda Shorebird Centre wetlands regularly hold grey teal.
