Call Ducks are primarily known for their very small size, and they are often referred to as toy ducks. Their bodies are short, as are their legs, and they have thin necks. They appear in a variety of colors. The Blue-Fawn male Call Duck has a gray blue breast and dark red body. The bill is green. Female Blue-Fawns have light brown bills and blue body feathers. The Silver drake's head resembles a mallard and its breast is a wine color. They have gray and black backs and green bills. The Silver female is primarily brown and gray colored. Apricot drakes resemble the Blue-Fawn variety, although they are lighter in color. The duck, however, is apricot and gray in color. White Call Ducks, regardless of the sex, are entirely white. Mallard Call Duck drakes have green and white heads and purple breasts. The back is green and gray. The Mallard Call Duck is primarily brown. Pied drakes have the same green and white head as the mallard, with a white ring around the neck, white underside and white tail feathers. The female is similar in coloration, but often has more white.
