Ducks - Diving and Dabbling
Wing sounds of Surf Scoters
Autumn brings millions of ducks flying south after nesting in the north. In most parts of North America, fall migration brings the greatest diversity of ducks we’ll see all year. Goldeneyes, scaup, wigeons and other species join familiar year-round ducks such as Mallards.
Quacking of mallards
Take a close look at autumn’s ducks as they forage on the water. Some dabble, while others dive.
Whistling calls of American Wigeon
“Dabbling ducks,” like the wigeons we’re hearing, feed by dipping their bills in water just below the surface, or dunking head first, so all you see are their tails pointing skyward.
Whistling calls of American Wigeons
They strain bits of vegetation and small invertebrates with their flattened bills.
“Diving ducks,” including scaup and mergansers, forage while swimming under water, using their feet or wings for propulsion. “Divers” with narrow, pointed bills snatch fish, while those with flatter bills, like Common Goldeneyes search along the bottom for invertebrates such as small clams.

When you stop by a lake or saltwater beach this fall, keep an eye out for “dabblers” and “divers.” And take your time, because the divers may pop into view only when they need to catch a breath of air.
