The oldest Gadwall duck on record was 19 years old.
Most male ducks sport elaborately colorful plumage, but the Gadwall males have an intricately woven pattern of silver-grey plumes, with a mix of brown and black. The females look a bit like female Mallards but with a darker and slenderer bill.
They are known as a pirate because they tend to snatch and then dash with food from diving ducks as they surface.
