The shallow, seasonal wetlands of the northern prairie pothole region — scattered across the Dakotas, Minnesota, and the prairie provinces — produce more ducks per acre than almost anywhere else in North America, and the green-winged teal (Anas crecca) is among the most abundant. Small, fast-flying, and quick to flush in tight, synchronized flocks, it is often the first dabbling duck a beginner learns to pick out by behavior alone.
North America's smallest dabbling duck. Breeding males show a rich chestnut head with an iridescent green eye-patch outlined in cream, a grey body, and a vertical white bar in front of the wing. Females are mottled brown overall, best told from other small ducks by size, the bright green speculum visible in flight, and their habit of associating in tight flocks with males.
Teal flocks are famous for their speed and agility — they twist, bank, and wheel in unison low over the water with a precision that looks almost choreographed, a trait that made them a classic waterfowl-hunting quarry and remains one of the most reliable ways to identify the species at a distance, well before plumage details are visible.
A duck defined by its flock, not the individual — watch for the wheeling formation before you ever pick out a single bird.
