These ducks use all four flyways, but are most plentiful in the west. They are extremely graceful and fast fliers, fond of zig-zagging from great heights before leveling off to land.
The long neck and tail make them appear longer than mallards, but in body size and weight they are smaller. They are agile on land and often feed in grain fields. The drakes whistle; the hens have a coarse quack.
