While the status of the Anatidae as a family is straightforward, and there is little debate about which species properly belong to it, the relationships of the different tribes and subfamilies within it are poorly understood. Alternatively, the Anatidae may be considered to consist of 3 subfamilies (ducks, geese, and swans, essentially) which contain the groups as presented here as tribes, with the swans separated as subfamily Cygninae, the goose subfamily Anserinae also containing the whistling ducks, and the Anatinae containing all other clades.

The word duck (from Anglo-Saxon dūce), meaning the bird, came from the verb "to duck" (from Anglo-Saxon supposed *dūcan) meaning "to bend down low as if to get under something" or "to dive".  All domestic ducks are descended from the wild Mallard Anas platyrhynchos, except the Muscovy Duck. Many domestic breeds have become much larger than their wild ancestor, with a "hull length" from base of neck to base of tail of 30 cm or more. A common urban legend says that quacks do not echo, however this has been shown to be false.

Duck is the common name for a number of species in the Anatidae family of birds. Ducks are mostly aquatic birds, mostly smaller than their relatives the swans and geese, and may be found in both fresh water and sea water.
Most ducks have a wide flat beak adapted for dredging. They exploit a variety of food sources such as grasses, aquatic plants, fish, insects, small amphibians, worms, and small molluscs.
Many species of duck are temporarily flightless while moulting; they seek out protected habitat with good food supplies during this period. This moult typically precedes migration. Some duck species, mainly those breeding in the temperate and Arctic Northern Hemisphere, are migratory; those in the tropics, however, are generally not. Some ducks, particularly in Australia where rainfall is patchy and erratic, are nomadic, seeking out the temporary lakes and pools that form after localised heavy rain.

The males of northern species often have extravagant plumage, but that is moulted in summer to give a similar appearance like females. Most people use "duck" specifically for adult females and "drake" for adult males. A duckling is a young duck in downy plumage or baby duck. Ducks have become an accepted presence in populated areas. Migration patterns have changed such that many species remain in an area during the winter months. In spring and early summer ducks sometimes influence human activity through their nesting; sometimes a duck pair nests well away from water, needing a long trek to water for the hatchlings.

A worldwide group like the ducks has many predators. Ducklings are particularly vulnerable, since their inability to fly makes them easy prey not only for avian hunters but also large fish like pike, crocodilians, and other aquatic hunters, including fish-eating birds such as herons. Ducks' nests may be raided by land-based predators, and brooding females may sometimes be caught unaware on the nest by mammals like foxes and large birds like hawks and eagles.
Adult ducks are fast fliers, but may be caught on the water by large aquatic predators. This can occasionally include fish such as the muskie in North America or the pike in Europe. In flight, ducks are safe from all but a few predators such as humans and the Peregrine Falcon, which regularly uses its speed and strength to catch ducks.

Diving ducks and sea ducks forage deep underwater. To be able to submerge more easily, the diving ducks are heavier than dabbling ducks, and therefore have more difficulty taking off to fly.
Dabbling ducks feed on the surface of water or on land, or as deep as they can reach by up-ending without completely submerging. Along the inside of the beak they have tiny rows of plates called lamellae like a whale's baleen. These let them filter water out of the side of their beaks and keep food inside.
A few specialized species such as the smew, goosander, and the mergansers are adapted to catch and swallow large fish.

Economics

Ducks have many economic uses, being farmed for their meat, eggs, feathers, (particularly their down). They are also kept and bred by aviculturists and often displayed in zoos. In many areas, wild ducks of various species are hunted for food or sport, by shooting, or formerly by decoys. From this came the expression "a sitting duck", which means "an easy target".
FAO reports that China is the top duck market in 2004 followed by Vietnam and other South East Asian countries. Foie gras is often made using the liver of domestic ducks, rather than of geese.
