Fun Facts about the Green-winged Teal
- Green-winged teals are among the fastest ducks, able to fly up to 60 mph.
- They are very active on foot and can run and walk for long distances.
- They capture smaller food items than other dabbling ducks due to the lamellae (closely spaced, comb-like projections) around the inner edge of their bill.
- The males whistle while the females quack.
