Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water.

This is most noticeable when the male puffs out the feathers on the head, thus greatly increasing the apparent size of the head. Description The bufflehead ranges from long and weighs , with the drakes larger than the females. Averaging and , it rivals the green-winged teal as the smallest American duck. The bufflehead has a wingspan of 21.6 in (55 cm). Adult males are striking black and white, with iridescent green ...
