22 Types of Grey Ducks (With Pictures & ID Guides)

In birds, grey plumage is always great for camouflage. Gray coloration helps birds blend into their environments, making them less visible to predators. This is also true of ducks—and perhaps the reason why many wild species display grey plumage.

But the fact that so many ducks wear shades of grey can make it difficult to tell them apart, especially when the similarities go well beyond size and overall color. Even so, while many grey ducks may look alike at first glance, a closer look usually reveals the subtle differences between them.

If you’re curious about the grey ducks you’ve spotted in a nearby pond or lake, the list below of 22 of the most popular species (along with an accompanying identification guide) will help you tell them apart with ease.

1. Grey Teal

At first glance, the Grey Teal wears a soft, understated mix of grey-brown plumage, finely mottled to create a smooth, almost dusty appearance. The grey tones are most noticeable across the neck and face, which appear paler than in similar species, giving the bird a gently washed look. In flight, however, this subtle duck reveals a flash of contrast—hints of green and white on the wings that briefly break through its otherwise muted coloring.

One thing that really stands out about Grey teals isn’t even their plumage but their eyes. They have a vivid crimson iris that stands out sharply against their calm, grey-toned bodies. They prefer shallow wetlands like lagoons, swamps, and freshwater lakes where its plumage mirrors the surrounding water and vegetation. The Grey Teal is highly adaptable when it comes to movement—it breeds across a wide range of regions including Australia and New Zealand, yet will readily wander beyond these areas when conditions change, appearing as a visitor in more distant islands.

2. Andean Teal

The Andean Teal is a small duck with soft grey-brown feathers that help it blend into high-altitude wetlands. Its head and chest are slightly paler, and delicate speckles break up the grey, making it hard to spot from a distance. In flight, you might catch a flash of darker wing markings that add a touch of contrast to its otherwise muted look.

This duck lives high in the Andes, and prefer mostly freshwater lakes and marshes in Colombia, Venezuela, and Ecuador. Unlike many ducks, it doesn’t migrate far—sometimes it just moves lower down the mountains when the weather changes. Though it’s not considered threatened, the loss of wetland habitats in the Andes is something to watch.

3. Blue Duck / Whio

This is the duck species on the reverse side of New Zealand’s $10 banknote. The Whio, or Blue Duck, wears a dark slate-grey coat with a greenish sheen on its head and a chestnut-speckled chest that adds a splash of color. Both males and females look similar, though females have slightly less chestnut, and its pale pink bill with small fleshy flaps makes it instantly recognizable.

Whio ducks prefer fast-flowing mountain rivers. It’s a powerful swimmer that’s able to handle strong currents with ease, but it rarely takes to the air. It is the male’s sharp, high-pitched whistle that inspired its Māori name, “Whio,” making this duck just as recognizable by its call as it is by its looks.

4. Gadwall

The male Gadwall is mostly grey with a black tail, soft chestnut on its wings, and a bright white patch on the wings that shows clearly in flight or when resting. Outside the breeding season, males look more like females but keep the white wing patch. Females are light brown (like a female mallard), but you can tell them apart by their white belly and dark orange-edged bill.

Gadwalls like open wetlands such as lakes, marshes, and wet grasslands with plenty of plants along the edges. They feed by dabbling, tipping their heads underwater to reach plants, and are masters at staying hidden while looking for food.

5. Garganey

Garganeys are true globe-trotters, traveling thousands of kilometers each year from Europe and northern Asia to spend the winter in Africa, India, Bangladesh, and Australasia. The male is easy to spot with its brown head and chest and a bold white crescent over the eye, while the rest of the body is soft grey with loose scapular feathers.

In flight, a pale blue patch on the wings bordered with white flashes, and when swimming, the edges of its wing feathers show bright white lines. Females are browner and more subtle, but you can tell them apart from similar ducks by their stronger face markings and frequent head-shaking while feeding.

The male’s crackling mating call is another distinctive feature, while the female is mostly quiet, making the male’s song a reliable way to locate them during the breeding season.

6. Maned Duck

Also known as the Australian Wood Duck, the Maned Duck is a familiar sight across much of Australia, including Tasmania. The male has a grey body with a dark brown head, a mottled chest, and thin white and black stripes along the sides. Females are a bit more patterned, with white stripes above and below the eye and mottled underparts. Both males and females share grey wings with black tips and a white patch on the wings that stands out when they fly.

These ducks are very adaptable and can be found in grasslands, open woodlands, wetlands, flooded pastures, and coastal inlets. They are mostly dabblers, and feed on plants in shallow water, and are often seen grazing on land, which is unusual for many other duck species.

7. Marbled Duck

The Marbled Duck is a rare and secretive species that prefers quiet wetlands and marshes. Adults have a pale sandy-brown body with off-white blotches, a dark patch around the eye, and a slightly shaggy head that gives them a soft, marbled look. Males and females look very similar, though females are a bit smaller, and juveniles show even more off-white markings. In flight, their wings appear pale and plain, lacking the bright wing patches seen in many other ducks.

Sadly, the Marbled Duck is considered near threatened because of habitat loss and hunting. Found across southern Europe, northern Africa, and western to central Asia, this duck is a gentle reminder of how delicate wetland ecosystems can be.

8. Freckled Duck

Sometimes referred to as the Monkey Duck or Oatmeal Duck, the Freckled Duck has one of the most unusual and eye-catching patterns among Australian waterfowls. Its dark grey to black feathers are covered in tiny white spots, giving it a true “freckled” look. Both sexes share slate-grey bills, legs, and feet. Freckled Ducks stick mostly to inland wetlands in eastern Australia, including New South Wales, Victoria, and Queensland, with smaller populations in South and Western Australia.

9. Patagonian Crested Duck

Found in the Falkland Islands and the southern regions of Chile and Argentina, the Patagonian Crested Duck prefers coastal bays and inland wetlands. Its grey chin, neck, and face blend with a mottled mix of brown and grey on the body, giving it a soft, camouflaged look. Dark feathers crown the head and surround its striking red eyes, while a black beak and dark grey legs and webbed feet complete its subtle, yet distinctive appearance.

These ducks are non-migratory, staying put through the colder months by finding sheltered spots. They thrive in marshes, lakes, swamps, and coastal inlets, quietly shaping the character of southern South America’s wetland landscapes.

10. Philippine Duck

The only endemic duck in the Philippines, the Philippine Duck has a black crown, nape, and eye stripe set against a warm cinnamon-colored head and neck, with greyish-brown body feathers and a bright green patch on the wings that shines in flight. Its legs are greyish-brown, and its bluish-grey bill completes the look. Females are slightly smaller than males but otherwise share the same coloring. This duck lives on all the major Philippine islands and several smaller ones, though most sightings today are on Luzon and Mindanao. Rare vagrants have even been spotted in Taiwan and Japan.

11. Pink-eared Duck

Also called the Zebra Duck, the Pink-eared Duck is a small but unmistakable Australian species. Its brown back and crown contrast sharply with black and white barred sides, and bold black eye patches stand out on an otherwise white face. They have large, spatula-shaped bills, which also make them easy to identify. They are highly mobile and can show up anywhere in Australia where standing water exists, especially in dry inland regions.

12. Yellow-billed Duck

The Yellow-billed Duck is a common duck of southern and eastern Africa, easily recognized by its bright yellow bill and mainly grey body with a slightly darker head. Its wings are whitish underneath, while from above you can see a green wing patch bordered with white. Males and females look alike, and juveniles are a little duller than the adults.

These ducks are not migratory, but they do wander during the dry season in search of water. Outside the breeding season, they are highly gregarious, often forming large flocks that can be a striking sight on African lakes and wetlands.

13. Green-winged Teal

These are the smallest dabbling duck in North America. The male has grey flanks and back, a yellow rear end, and a green wing patch edged in white that stands out in flight or at rest. Its chestnut head with a bright green eye patch and a vertical white stripe on the breast help distinguish it from similar Eurasian teals.

These ducks live in sheltered wetlands, including bogs and shallow ponds, where they feed by dabbling in the water or grazing on land. Despite their small size, Green-winged Teals are widespread and abundant, showing how even the tiniest ducks can thrive across vast landscapes.

14. Yellow-billed Teal

The Yellow-billed Teal is a widespread duck of South America, found from Argentina and Chile to Brazil, Uruguay, and even the Falkland Islands. It has mostly grey body with a darker head, which is further complemented by a bright yellow bill, making it easy to spot. The wings show a green patch edged with white from above, and appear whitish from below. Males and females look very similar, while juveniles are slightly duller. Its northeastern subspecies has a darker body, brighter bill, and a blue-tinted wing patch.

These teals prefer freshwater wetlands, especially marshy areas rather than rivers. They are well adapted to a variety of habitats, and some populations have even established themselves on remote islands like South Georgia, showing their ability to thrive far from the mainland.

15. Falcated Duck

The Falcated Duck is a long-distance traveler, migrating across Asia and spending winters in Southeast Asia. The male is striking, with finely patterned grey feathers on most of its body and long, curved wing feathers ( tertials) hat hang gracefully off its back, giving the duck its name. Its head is dark green with a white throat, a bronzed crown, and a green collar, while the vent shows a mix of yellow, black, and white.

Females are dark brown, similar to a female wigeon, but their long grey bill helps tell them apart. These ducks prefer wetlands where they can dabble for food, and their unique wing shape and colorful patterns make the males especially noticeable during the breeding season.

16. Chubut Steamer Duck

Originally thought to be found only along the southern coast of Chubut Province in Argentina, the Chubut Steamer Duck actually has a larger range, stretching from the southern part of San Matías Gulf to Islote Chato. Its most important populations live in Bahía San Gregorio, Bahía Melo, and Caleta Malaspina in the San Jorge Gulf.

Adult males have white heads and bright yellow-orange bills with a black tip, and their webbed feet match the bill with yellow-orange coloring and black claws. The body is mostly grey with a white belly, and during molting, the bill dulls slightly. These ducks are powerful swimmers and use their strong wings to “steam” across water, making them well adapted to the coastal habitats of southern Argentina.

17. Falkland Steamer Duck

The Falkland Steamer Duck is a flightless duck found only on the Falkland Islands in the South Atlantic. The male has brown to grey body feathers with a pale grey-white head and a bright orange bill that stands out. Its wings show white secondary feathers and large featherless spurs, while a short brown-grey tail completes its compact look. The eyes are brown, highlighted by a white eye-ring and faint eye-streak that give it a sharp expression.

These ducks are strong swimmers, using their powerful wings to paddle across water instead of flying. Their flightless nature and bold appearance make them a unique and unmistakable part of the Falkland Islands’ wildlife.

18. Flying Steamer Duck

These are the smallest of the four steamer duck species, but they share many features with their larger relatives. They have brown heads and necks with white stripes running from the eyes to the back of the neck, and their bodies show a soft brown-grey gradient. Their underbellies are mostly white, and their feet are bright orange. Males have darker grey bills with a hint of yellow, while females’ bills are smaller and orange with black tips.

Flying Steamer Ducks live in southern South America, including Chile, Argentina, Tierra del Fuego, and the Falkland Islands. They prefer coastal waters and sheltered bays, and despite their small size, they are strong swimmers that use their wings to “steam” across the water, just like the other steamer ducks.

19. Fuegian Steamer Duck

This is the largest of all steamer ducks, with males weighing between 3.5 and 7 kg and measuring up to 84 cm long. Males are noticeably bigger than females, giving them a commanding presence on South American waters. The male has a blue-gray head and neck, a paler crown and forehead, a narrow white eye-ring that continues as a stripe, and a reddish-brown throat. Its abdomen, vent, and undertail are white, while the tail is grey. Females are darker, with a gray-brown head and a dark reddish throat, and may show brown or wine-colored feathers on their body and wings.

Native to southern South America, these flightless ducks dominate coastal waters and sheltered bays. Despite being unable to fly, their powerful build and strong swimming skills make them masters of their habitat, able to move quickly across water and defend their territory with confidence.

20. Eastern Spot-billed Duck

Also known as the Chinese Spot-billed Duck, this dabbling duck breeds across East and Southeast Asia and migrates south in the winter to places like southern China. It has a mostly grey body with a paler head and neck, and a black bill tipped with bright yellow. The wings are whitish underneath with black flight feathers, and from above you can see a green patch edged in white.

Outside the breeding season, Eastern Spot-billed Ducks are social birds, often forming small flocks. Populations in Japan and the Russian Far East have even expanded northwards in recent years, showing how adaptable this duck is to different wetland habitats.

21. Indian Spot-billed Duck

The Indian Spot-billed Duck gets its name from the red spot at the base of the male’s bill, a feature that sets it apart from other similar ducks. Its body is mainly grey with a paler head and neck, and a black bill tipped with bright yellow. The wings are whitish underneath with black flight feathers, and from above you can see a green wing patch bordered in white. In water, the white-edged tertials form a stripe along the side, making it visible from a distance, while in flight, the green-and-white wing patch stands out.

These ducks are residents throughout Pakistan and India, and prefer medium-sized wetlands with plenty of vegetation to very large open waters. Females are smaller and usually lack the red spot on the bill, but otherwise look much like the males.

22. Northern Pintail

With its slender, graceful shape and long tail feathers, the Northern Pintail is one of the most elegant dabbling ducks. The male stands out with a chocolate-brown head, white breast, and a thin white stripe running down the neck, while elongated grey feathers with black stripes drape across its back. Its yellow vent contrasts sharply with the black underside of the tail, and the central tail feathers can grow nearly 10 cm long. Females are more muted, sporting drab brown plumage that helps them stay hidden while nesting.

These ducks are true migrants, breeding across northern Europe, Asia, and North America, then traveling south in winter to regions as far as Panama, northern sub-Saharan Africa, and tropical South Asia. They thrive in shallow wetlands and marshes, feeding by dabbling for aquatic plants.
