We've gathered a selection of 14 species that are way more unusual than your average mallard at the local pond (though mallards are gorgeous ducks, too). We can't stop staring at these species! Harlequin duck While we typically think of ducks as quietly meandering around ponds, a few species live their lives in much rougher waters. The gorgeous sea duck pictured above is one of them. Found along fast-moving streams and rocky coastlines, the males of this species have a complex plumage pattern. The species goes by many names, including painted duck, sea mouse, rock duck, glacier duck and white-eyed diver. King eider With the yellow knob on its beak, the king eider has a very distinctive face. AndreAnita/Shutterstock Few duck species have more distinctive faces than the eiders. The prominent yellow knob at the top of male king eiders' beaks is the source of their name, as the knob resembles a crown. The king eider is an arctic species, breeding on the tundra during summer and spending winters at sea, diving as deep as 80 feet to feed on crustaceans, mollusks and other prey. Long-tailed duck The long-tailed duck is a deep diver, swimming as far as 200 feet below the surface for food. Elliotte Rusty Harold/Shutterstock The long-tailed duck has fancy plumage from head to extra-special tail. This species is one of the deepest-diving ducks, swimming as far as 200 feet below the surface of the ocean for food. According to the Cornell Lab of Ornithology, the species spends more time underwater than at the surface compared with other diving ducks. The long tail is actually two extra-long central tail feathers. Mandarin duck The male mandarin duck has impressively colorful plumage. Panu Ruangjan/Shutterstock This perching duck species is native to East Asia, though it can now be found in several parts of the world including England, Ireland and California, as captive individuals escaped and created wild breeding populations. The wild ducks in Asia, however, face a population decline due to logging and habitat loss. Thankfully for these ducks, despite the males' impressive breeding plumage, they are not typically targeted by hunters. "One factor that has helped the Mandarin to survive," according to the University of Michigan Museum of Zoology, "is their bad taste." Hooded merganser The hooded merganser is known for its striking crest. Paul Reeves Photography/Shutterstock The extraordinary crest on this little duck is the source of its name. Both males and females have crests they can raise in display, but only the male has the striking black-and-white coloring. Males raise their crest and perform a head-bobbing maneuver when trying to impress females during courtship. These small ducks can be found on ponds and in streams diving for fish, insects and other invertebrates. Pink-eared duck With that burst of pink on its head, it's easy to see how the pink-eared duck got its name. Katarina Christenson/Shutterstock This unusual duck species is named for the flash of punk-rock pink on the side of its head, but its most distinguishing feature is actually its bill. According to the Guardian, "The large, flat, square-ended bill evolved for filter-feeding: The bill is fringed with fine lamellae (grooves) that filter microscopic plants and animals that make up most of this species' diet. The pink-eared duck can often be seen with its bill submerged in shallow, warm waters and it often feeds circling head-to-tail in pairs or groups." With such a distinctive look, this Australian species is never mistaken for any other species. Smew duck The smew duck is known for its unique black-and-white coloring. Bildagentur Zoonar GmbH/Shutterstock The smew is another species of merganser found in Europe and Asia. It is unmistakable in its black-and-white plumage. The males of this species are snow-white with black accents on the wings and chest, black "panda" eye markings, and a streak of black along the crest atop the head. They can be found nesting in the taiga of Europe and Asia, taking advantage of crevices in trees, such as woodpecker holes, to raise their young. Spectacled eider The spectacled eider is aptly named for its distinctive face. Robert L. Kothenbeutel/Shutterstock Another eider species with an incredibly distinctive face is the spectacled eider — named such for obvious reasons. The pale green patch of feathers on the back of its head and the vividly orange bill of the males help to exaggerate the spectacle-like eye markings even more. These beautiful birds are found in coastal Alaska and Siberia, nesting on the tundra during summer. The species is not very well known, is not very common and is on the decline. The breeding population in western Alaska declined by 96 percent from 1970 to 1993. Surf scoter Thanks to its unusual face, the surf scoter is nicknamed 'skunk-headed coot.'. Steve Byland/Shutterstock The surf scoter has a striking face, one that has earned it the nickname of "skunk-headed coot." Its markings and build make it look a bit like a mix between the harlequin duck and an eider. Surf scoters are found in coastal waters of the Pacific and Atlantic during summer, where they dine on mollusks, crustaceans, aquatic insects and other small prey. White-faced whistling duck The white-faced whistling duck makes a sound much like a squeaker-toy whistle. Vladimir Wrangel/Shutterstock This beautiful duck species is fascinating not only for its looks but also its call. It's named a whistling duck because the sound it makes is much like a squeaker-toy whistle. Have a listen: Baikal teal The Baikal teal is popular with birders because of its gorgeous plumage. Daniel Prudek/Shutterstock From the iridescent patch of green on the back of the male's head to the pheasant-like feathers decorating its shoulders, this beautiful duck species is one birders could watch for hours. The Baikal teal easily stands out from other teal species with plumage that is recognizable from a distance. The species is native to eastern Asia, and sometimes though rarely is spotted in Alaska. Though the species took a downturn in the late 20th century due to hunting and habitat loss, it seems to be rebounding, with an estimated 1 million individuals as of 2010. Wood duck The vibrant wood duck is one of the most colorful water-bird species in North America. Keneva Photography/Shutterstock The wood duck is related to the mandarin duck, and you might see a family resemblance in the wild array of colors and markings and the elaborate crest on the head. This is one of the most colorful water-bird species in North America. The species suffered a serious decline and near extinction in the late 19th century due to hunting and the loss of large trees where the ducks nest. Conservation efforts — including habitat preservation, thousands of nesting boxes and an end to unregulated hunting — have brought wood ducks back. Ruddy duck The ruddy duck has a bright blue bill that fades to gray in winter. Herman Veenendaal/Shutterstock This handsome fellow is a ruddy duck. The species easily stands out from the crowd thanks to a brilliant blue bill. Males have this plumage and bill color during the breeding season, when they want to look their best for any interested females. During winter, their shiny chestnut bodies as well as their blue bill fade to gray. Northern shoveler Although it looks like a mallard, the northern shoveler is different because of its oversized bill. Bildagentur Zoonar GmbH/Shutterstock While this species' markings may look much like a mallard, you can certainly tell it apart by its oversized bill. The northern shoveler has an elongated, spoon-shaped bill that features 110 comb-like projections along the edges. These help the duck filter out small crustaceans and other invertebrates from the water. Because its bill is so specialized for sifting through muddy marshes, it doesn't have to compete with other paddling ducks for food during much of the year.
