wards the centre of their bodies. They walk well on land, and some species feed terrestrially.

"Puddle ducks" generally feed on the surface of the water or feed on very shallow bottoms. They are not equipped to dive down several feet like their diving counterparts. The most prominent difference between puddle ducks and divers is the size of the feet. A puddle duck's feet are generally smaller because they do not need the extra propulsion to dive for their forage.

Another distinguishing characteristic of puddle ducks when compared with diving ducks is the way in which they take flight when spooked or are on the move. Puddle ducks spring straight up from the water, but diving ducks need to gain momentum to take off, so they must run across the water a short distance to gain flight.

Traditionally, most ducks were assigned to either the shelducks, the perching ducks, and the dabbling and diving ducks; the latter two were presumed to make up the Anatinae. However, the perching ducks turned out to be a paraphyletic assemblage of various tropical waterfowl that happened to evolve the ability to perch well in their forested habitat. Several of these, such as the Brazilian teal, were subsequently assigned to the Anatinae.

As for the diving ducks, mtDNA cytochrome b and NADH dehydrogenase subunit 2 sequence data indicates that they are fairly distant from the dabbling ducks. The morphological similarities are due to convergent evolution.

In addition, the genus Anas, as traditionally defined, is not monophyletic; several South American speci
