Key field marks

Smallest dabbling duck, iridescent green head patch on males, horizontal white scapular line along the back, and buffy patch under the tail.

Size & weight

Length: 31-39 cm (12-15 inches), Wingspan: 58-64 cm (23-25 inches), Weight: 140-500 g (5-18 oz)

Voice — call & song

Males give a clear, musical, rising whistle (kree-eek), while females emit a soft, low quack.

Diet & foraging

Primarily feeds on seeds of aquatic grasses, sedges, and weeds, as well as aquatic insects, crustaceans, and mollusks by dabbling or tipping up in shallow water.

Habitat

Shallow freshwater marshes, ponds, estuaries, sheltered coastal bays, and flooded fields.

Migration & movement

Strongly migratory, traveling in flocks from northern breeding grounds to southern wintering areas.

Nesting & breeding

Nests on the ground in well-concealed spots among tall grass or shrubs near water. Lays 6 to 11 creamy-white or buff eggs. Incubation is done entirely by the female for about 21 to 23 days.

Similar species

Eurasian Teal (Anas crecca), which males differ from primarily by lacking the vertical white breast stripe, though the two are often considered conspecific.

Ecological significance

Acts as an important seed disperser for aquatic plants and helps control invertebrate populations in wetland ecosystems.

Conservation status

Least Concern, with stable populations globally.

Observation tips

Look for them in shallow wetlands, marshes, and flooded agricultural fields, often feeding alongside other dabbling ducks. They are skittish and flush quickly when approached.

Interesting facts

Despite their small size, Green-winged Teals are exceptionally strong flyers capable of taking off vertically straight out of the water.
