The term waterfowl is used to describe any member of the order Anseriformes. A series of articles describes all the waterfowl. This specific article describes the "dabbling ducks" which belong to family Anatidae, subfamily Anatinae.
Anseriformes
Most species of the order Anseriformes spend a considerable amount of time in water. In fact, they are called waterfowls. Their webbed feet make for efficient swimming. A few species spend little time in water and thus their feet are only partially webbed. Most waterfowl are also good flyers, many migrating long distances to escape the cold and others migrating shorter distances for optimizing their food supply. All species, except the screamers, have a wide and relatively flat bill. The shape of a species bill and also their tongue is a function of their diet. Considering the entire order, they eat aquatic plants, grasses, sedges, algae, plankton, insects, insect larvae, mollusks, crustaceans, fish, fruits, grains, rice. Most species are monogamous and if they lose a partner seem to mourn. Males are larger and heavier than females. The chicks are well developed when they hatch and can walk almost immediately.
The order Anseriformes has 3 familes: Anatidae, Anhimidae, Anseranatidae. Family Anatidae is comprised of the ducks, swans, and geese which amounts to about 160 species. Family Anhimidae is made up of 3 screamer species while family Anseranatidae has only one species, the magpie goose. Since these latter two families contain so few species, it seems appropriate to consider the entire order in this series of articles.
Anatidae
The Anatidae family has the following subfamiles:
Anatinae: dabbling ducks and teals
Anserinae: geese, swans
Aythyinae: diving ducks
Dendrocygninae: whistling ducks
Merginae: sea-ducks
Oxyurinae: stiff-tailed ducks
Plectropterinae: spur-winged goose
Stictonettinae: freckled duck
Tadorninae: shelducks, shelgeese
Dabbling Ducks
The members of subfamily Anatinae are refered to as dabbling ducks because they do not totally submerge when feeding and are often seen with just their rears showing as they search for food. Because of their feeding method, dabbling ducks have evolved to be more buoyant than diving ducks. The dabbling duck only rarely dives. In fact, the stiff-tailed ducks that do dive and yet have been placed in Anatinae, is placed by some (including this author) in its own sub-family.
Not all species in this subfamily have "duck" in their name. Other names used are gadwall, garganey, mallard, pintail, shoveler, teal, and wigeon.
The genus that contains the most species is Anas. This genus used to contain even more species, as it has often been a "catch all" for species that were only distantly related. More species may be removed in the future. Many of the anas species are closely related to mallards. Mallards are a very wide spread species and have been so for a very long time. After a considerable time, "mallards" in a particular region have evolved to have their own characterestics thus leading to a new species. But "true" mallards may inter-breed wild mallard-like species thus producing hybrids which can present identification problems.
Speculum
The speculum is a patch on the upper surface of secondary feathers. For the mallard show below, it is the bright blue patch plus the white borders.

Not all birds have speculums. The dabbling ducks have especially vivid speculums many of which are iridescent. The speculum is best seen while the duck is in flight; when the duck is at rest the speculum may be partially or completely hidden. Very often careful observation of a duck's speculum is sufficient to identify the species. Pay attention not to just the main color of the speculum, but also the top and bottom borders. These borders are often referred to as the "leading edge" and "trailing edge" respectively.
A duck's speculum can be considered to be its barcode. Read it carefully and you can know the species. Of course speculums did not evolve to make birders happy! They must have evolved to help ducks easily recognize kindred spirits. In the material that follows, when possible a speculum image is included for each species.
Habitat and Diet
It is not surprising that the dabbling duck subfamily preferred habitat is water. Most prefer freshwater, at least for a considerable portion of the year. Some will choose brackish or saline habitats in the winter. The purpose of dabbling is to obtain food which implies that dabbling duck prefer shallow wetlands so they can reach the bottom. The typical dabbling duck's diet is comprised of aquatic vegetables and insects, seeds, crustaceans, and mollusks. In a number of species, the juveniles often have a higher proportion of invertebrates than the more vegetarian adults.
Genus Anas
This genus is the prototype for dabbling ducks. Most of the species are buoyant and will dabble with the head under water and the rear above water pointing skyward. The genus contains many species that are termed teals, but they are not included in this article. See teals.

Genus Spatula
The shovelers have very long bills. Their wide-flat bill is equipped with small, comb-like structures on the edge of the bill that act like sieves, allowing the birds to skim crustaceans and plankton from the water's surface. The genus contains many species that are termed teals, but they are not included in this article. See teals.
Garganey Spatula querquedula
Description: The male garganey has a brown head and breast, a reddish-brown face, and a broad white crescent over the eye. The rest of the plumage is grey as well as the bill and legs. The brown female garganey has a dark eye-line with a pale supercilium above. There is a white loral spot. The speculum is green (male) or greenish-brown (female). The female can be told from the female blue-winged by that specie's white eye-ring. Its white loral spot helps to differentiate the female garganey from the female green-winged teal.
Range: Europe, Asia, Africa, Australasia.
Habitat: Wetlands with vegetation showing above the surface.
Diet: Aquatic plants, seeds, fish, mollusks, crustaceans, This species feeds mainly by skimming rather than upending.
Conservation status: Least Concern.
