The different types of wild ducks can be grouped into puddle, aka “dabbling” and diving ducks. The dabblers mostly feed in smaller bodies of shallow water or along shorelines, where they are able to tip their bodies forward to reach their food on the bottom. There are divers who feed in deeper water where they dive and pursue their quarry. Some of these birds, the Harlequin Duck for example, actually dives to the bottom of fast-flowing waters and feeds on life forms attached to rocks.
