Ducks, Geese and Swans
Available Titles
Mandarin Duck (Aix galericulata)Mandarin Duck (Aix galericulata) One of the most colorful of all ducks, the male Mandarin duck has a red bill, large large white crescent above eye, reddish face and "whiskers," purple breast with two vertical white bars, and orange flanks. Mandarin ducks symbolize wedded bliss and fidelity in traditional Chinese culture.
Northern Pintail (Anas acuta)Northern Pintail (Anas acuta) Also known as sprigs, pintails are fairly small ducks, having a wingspan of about 9 to 11 inches, a body length of 23 to 30 inches and weighing between 1 and 3 pounds. Adult male pintails have a long, thin tail feather than can measure up to 4 inches long. This feather narrows down to a sharp point and is where they get their common name.
American Wigeon (Anas americana)American Wigeon (Anas americana) This species is distinguished from other dabbling ducks by its small bill, the male's white forehead (which also accounts for the alternative name of "baldpate"), and certain aspects of its nesting and feeding behavior. Other characteristic features include the male's bright green face patch, a large white patch on each wing, and a black rear end bordered by white.
Northern Shoveler (Anas clypeata)Northern Shoveler (Anas clypeata) The head, neck, and speculum of male northern shovelers are iridescent green, their chests are white, and the remaining underparts are a bright chestnut. The most distinctive feature of the shoveler is its bill, which is twice as wide at the tip than at the base. This uniquely-shaped bill accounts for this species' common names -- shoveler and spoonbill.
Green-Winged Teal (Anas crecca)Green-Winged Teal (Anas crecca) The smallest dabbling duck in the Americas, the green-winged teal is 13-17 inches long and weighs 13 ounces on average; males are slightly larger than females. Green-winged teals are rapid, agile flyers, and are the only ducks known to scratch while in flight.
Cinnamon Teal (Anas cyanoptera)Cinnamon Teal (Anas cyanoptera) average about 16 inches in length, have an average wingspan of about 7½ inches, and weigh approximately 12 ounces. An adult male's head, chest, and underside is generally purple-chestnut, and the abdomen is dark brown. They take off to flight directly from water, as opposed to the "running start" procedure used by other ducks.
Blue-Winged Teal (Anas discors)Blue-Winged Teal (Anas discors) One of the smallest members of the duck family, the blue-winged teal is 14 to 16 inches long, has a wingspan of 22 to 24 inches, and weighs between 8 and 19 ounces. Both sexes have large light blue patches on the front of each wing, visible in flight.
Mallard (Anas platyrhynchos)The Mallard (Anas platyrhynchos) may very well be the most easily recognized waterfowl in the world. The male (drake) is brightly colored from September to June. His belly and most of his back are gray. His head and neck are a dark glossy green and a white ring at the base of the neck separates the green from the brown of the breast. The familiar quack of ducks is from the female mallard. She will give the call when she wants to bring other ducks to her.
Black Duck (Anas rubripes)Black Duck (Anas rubripes) Breeding males have a buffy head that is heavily streaked with black, especially through the eye and on the tip of the head. In flight, the black duck appears to be nearly black, with an underwing coloration that is in contrast with the rest of its plumage.
Gadwall (Anas strepera)Gadwall (Anas strepera) Gadwalls range in size from 18 to 22 inches long and 1 to 2½ pounds in weight, with both sexes being about the same size. A white speculum is the most distinctive marking on a gadwall, but it is only visible when the bird is in flight.
White-Fronted Goose (Anser albifrons)White-Fronted Goose (Anser albifrons) A medium-sized goose, the white-fronted averages 25 to 32 inches in length, has an average wingspan of 53 inches, and weighs between four and nine pounds. The least distinctively marked of all the geese, white-fronteds are often confused with domestic geese, although domestics lack the black belly markings and have thinner necks and bigger bellies.
Snow Goose (Anser caerulescens)Snow Goose (Anser caerulescens) Snow geese come in two basic "color schemes" -- an adult "snow snow goose" is snowy white, while an adult "blue snow goose" is blue/gray. The colors appear to be genetically determined. Individual snow geese tend to choose mates that resemble their parents, but "mixed" breeding is not uncommon.
Lesser Scaup (Aythys affinus)Lesser Scaup (Aythya affinis) This medium-sized diving duck is 15 to 18 inches long, has a wingspan of 27 to 31 inches, and weighs between 1 and 2½ pounds. The bill is bluish with a small black tip, the eyes are yellow, and the legs are grayish with dark gray webs.
Redhead (Aythya americana)Redhead (Aythya americana) This large diving duck gets its name from the male's chestnut-red head. The male redhead has a high, up-and-downish forehead. His feet are bluish gray, and his eyes are orange-yellow. Both the male and female have a pale blue bill with a white ring around the black tip.
Ring-Necked Duck (Aythya collaris)Ring-Necked Duck (Aythya collaris) An adult male ring-necked duck has a large body that is about 7½ to 8 inches long; the female is slightly smaller. His head, neck and breast are black, he has gray flanks, and there is a white crescent separating the flanks from the breast. The female has tan sides, a brown back and a white belly. Both sexes have a black tip and a ring of gray on their bill, although the female's bill ring is less pronounced than the male's.
Canvasback (Aythya valisineria)The Canvasback (Aythya valisineria) is distinguished from other ducks by its sloping profile. The male has a rusty red head, white body, and black chest and rear end. The female is drabber and marked in brown and gray.
Brant (Branta bernicla)The Brant (Branta bernicla) is a small- to medium-sized goose, averaging about 24 inches in body length and weighing between 42 and 63 ounces.
Canada Goose (Branta canadensis)The Canada Goose (Branta canadensis) is a large (up to nine pounds) gray-brown bird with black head and neck and a white patch extending from the chin, up the cheeks to behind the eyes. The tail is black while the feathers around the base of the tail are white. Canada geese are rarely found alone. They fly in flocks in the form of a "V" or a diagonally straight line.
Bufflehead (Bucephala albeola)Bufflehead (Bucephala albeola) This short-billed diving duck is called a bufflehead because its high, rounded head looks a bit too large and puffy for its body. The smallest duck in North America, the bufflehead is only 13 to 16 inches long, and has a wingspan of no more than 22 inches. Unlike most ducks, buffleheads form long-term mating pairs.
Common Goldeneye (Bucephala clangula)The Common Goldeneye (Bucephalus clangula) is distinguished from other goldeneyes by its puffy head shape and a large white wing patch that is conspicuous in flight. And, in flight, its wings produce a characteristic whistling sound. Males have a white body, black back, and iridescent green head, while females are mostly gray and have a dark brown head.
Barrow's Goldeneye (Bucephala islandica)Barrow's Goldeneye (Bucephala islandica) is characterized by its chunky body and large head with steep forehead. One of the longest living of the ducks, Barrow's goldeneyes may reach an age of up to 18 years. In fact, most females don't even breed until after reaching their third year.
Emperor Goose (Chen canagica)The Emperor Goose (Chen canagica) is a medium-sized goose -- 26 to 28 inches long and weighing about 6 pounds. Most emperor geese spend the entire year on the west coast of Alaska, on the Aleutian Islands, or along the eastern coast of Siberia.
Ross' Goose (Chen rossi)Ross' Goose (Chen rossi) is small compared to many other members of the geese family -- about 24 inches long, a wingspan of about 45 inches, and weighing between 30 and 72 ounces. It is completely white except for black primaries, a greenish warty patch at the base of a pink bill, and dark pink legs.
Trumpeter Swan (Cygnus buccinator)Trumpeter Swan (Cygnus buccinator) Once fairly widespread, trumpeter swans are now only found in isolated populations in western Canada and the western United States. It inhabits lakes, ponds, large rivers, bays, and sometimes grain fields with large ponds.
Tundra Swan (Cygnus columbianus)The Tundra Swan (Cygnus columbianus), also known as the whistling swan, can be distinguished from other swans by the presence of a yellow spot at the base of its black beak, the black of the bill extending up to the eye but not encircling it, and the straight demarcation on the forehead between black bill and white feathering.
Mute Swan (Cygnus olor)Mute Swan (Cygnus olor) The most distinguishing features of the mute swan is a black "knob" at the base up the upper bill, and the color of the bill itself, which is orange, with the tip and base colored black. Contrary to the stereotype of the "pining swan" who has lost its mate, mute swans do not actually pair for life.
Harlequin Duck (Histrionicus histrionicus)Harlequin Duck (Histrionicus histrionicus) The male harlequin is blue-gray, appearing black at a distance, with chestnut flanks, wedge on head, and has distinctive white patches on the head and body. These expert swimmers are capable of riding rapids, diving and probing among the bottom stones of swift rivers and streams.
Hooded Merganser (Lophodytes cucullatus)The Hooded Merganser (Lophodytes cucullatus) is the smallest North American merganser. In addition to its small size, it is distinguished from the other mergansers by its brownish-black back and wings, black head with white, fan-shaped crest bordered in black, and white underside. Hooded mergansers are clumsy, but quick, flyers. They take off by running across the water to gain flight speed, and often land by "skiing" across the water to come to a stop.
White-Winged Scoter (Melanitta fusca)White-Winged Scoter (Melanitta fusca) This large, stocky diving duck is 19 to 23 inches long, has a wingspan of about 30 inches, and weighs between 2 and 4 pounds. Males are black except for a white comma-shaped patch around the eyes and a white patch on each wing that is only visible in flight.
Surf Scoter (Melanitta perspicillata)Surf Scoter (Melanitta perspicillata) This large, stocky diving duck is 19 to 24 inches long, has a wingspan of about 30 inches, and weighs between 2 and 4 pounds. The male is entirely black except for one or two white patches on the face. He has a large bill that is patterned with white, red, yellow, and black patch near the base.
Red-Breasted Merganser (Mergus serrator)Red-Breasted Merganser (Mergus serrator) This large, thin diving duck is 20 to 25 inches long, has a wingspan of 26 to 29 inches, and weighs 1½ to 3 pounds. It is differentiated from other mergansers by its extra-long, shaggy crest and white wing patches.
Ruddy Duck (Oxyura jamaicensis)Ruddy Duck (Oxyura jamaicensis) In the spring, the male sports a red-brown chest, rump and flank, and a white streak on the cheeks. Characteristics of the species include large gray feet and a concave bill, which is gray is the winter but will change to a blue-gray in the spring for males. Ruddy ducks are poor fliers and require long "runways" to get airborne, so their best defense against danger is to either swim or dive.
Steller's Eider (Polysticta stelleri)Steller's Eider (Polysticta stelleri) The smallest of the eiders, this duck is only 17 to 18 inches long. It is characterized by a small, thick-based, and slightly drooping bill, steep forehead and nape, and a long, pointed tail held above the water.
Spectacled Eider (Somateria fischeri)The Spectacled Eider (Somateria fischeri) differs from other eiders in that its feathers extend down to the nostrils on the bill, which is bright orange on males and blue-gray on females. Males have a black chest and pale green head, but are best distinguished by the white patches around their eyes, which are encircled by black feathers to give the appearance of spectacles.
King Eider (Somateria spectabilis)King Eider (Somateria spectabilis) This large, stocky duck weighs between 3½ and 4½ pounds, and is 19 to 25 inches long. During the breeding season the male is black and white with a brightly colored head, light blue crown and nape, greenish face, and bright red-orange bill with large orange knob outlined with black.
