  • Scientific Name: Oxyura australis
  • Lifespan: 10 years
  • Wingspan: 23.6 in
  • Beak Color: Bright blue

Blue-billed ducks are small stiff-tailed ducks – they have long and stiff tail feathers held erected when resting. 

They are native to Australia and inhabit inland wetlands but also artificial wetlands, like sewage ponds. 

Male blue-billed ducks have intense chestnut and black colors and bright blue bills. When the breeding season ends, their elongated bills turn slate blue. 

Females are dark grayish. 

Compared to other ducks, blue-billed ducks sit lower in water and are unlikely to be spotted on land. 

They have difficulty walking and mostly move as penguins do. 

Blue-billed ducks are very social birds and when the non-breeding season comes, they form huge flocks including several hundred. 

They breed from November to March and gather around deep, freshwater swamps with dense vegetation; during the non-breeding season, they are most common around open lakes or dams, far from the shore.

Blue-billed ducks are omnivores and feed on seeds, buds, fruits, underwater plants, small invertebrates like mollusks, and aquatic insects. 

These diving birds can also stay underwater for around 10 seconds while feeding.


Ruddy Duck

ruddy duck
  • Scientific Name: Oxyura jamaicensis
  • Lifespan: up to 13 years
  • Wingspan: 18.5 in
  • Beak Color: Bright blue

Another stiff-tailed bird on our list of ducks with blue bills is the ruddy duck.

This small North American duck is found in the western and southern parts of the USA. 

Identify it by the long stiff tail, short neck, black cap, and white cheeks. 

Male ruddy ducks have rich chestnut plumage and bright blue scoop-shaped bills during summer. 

When the winter comes, they become gray-brown and their beaks become dull grayish-blue. 

Females and immatures have brown plumage, dark caps, and a dark line through their cheeks.

Ruddy ducks breed in marshy lakes and ponds. Females will use grass to build the nests in tall vegetation and lay 5-15 whitish eggs. They have the largest eggs of all ducks, compared to their body size. 

Ruddy ducks become very aggressive during the breeding season; they can be spotted chasing away rabbits feeding on the shore close to them!

When the winter comes, these migratory ducks move to coastal bays and unfrozen lakes and ponds. 

Ruddy ducks are omnivorous and feed on insects, crustaceans, and aquatic plants; they will also dive to grab food. 

Although mainly silent, they might make some nasal calls, high-pitched calls, and hisses when feeling threatened. Males only have belch-like calls they use during courtship.

As part of their courtship ritual, male ruddy ducks will also perform a “bubbling display” where they will beat their bills against their chests in a rapid fashion, forcing air bubbles from their feathers.


American Wigeon

  • Scientific Name: Mareca americana
  • Lifespan: 2 years
  • Wingspan: 30-36 in
  • Beak Color: Pale blue

American wigeons are medium-sized dabbling ducks native to North America. 

They are nicknamed “baldpates” due to the white crowns and foreheads of males.

Identify American wigeons by their round heads and short necks. 

Males have pale cinnamon plumage, white caps, green stripes behind the eyes, and white bellies. Females are warm brown with brownish heads. 

American wigeons also have short pale blue bills with black tips. 

Due to the shorter size of their beaks, they can exert more force at the tip and pluck vegetation more easily.

Recognize these noisy ducks by their distinctive calls; males make wheezy “whoe-whoe” sounds while the females make low “qua-ack” ones. 

American wigeons breed from April to May around wetlands, ponds, lakes, marshes, and rivers of Northern Canada and northwestern parts of the USA (including Idaho, Colorado, Minnesota, Oregon, and Washington). 

They build their nests on the ground, around grasslands and fields, and lay 6-12 creamy white eggs. 

They are migratory ducks and move to southern parts of the USA, Central America, the Caribbean, and parts of South America for winter. 

American wigeons are omnivores that feed on aquatic and terrestrial plants and insects and aquatic invertebrates, especially during the breeding season. 


Northern Pintail

Northern Pintail
  • Scientific Name: Anas acuta
  • Lifespan: up to 22 years in the wild
  • Wingspan: 31-37 in
  • Beak Color: Bluish gray

Northern pintails are rather large ducks widespread across North America, Europe, and Asia. 

They are one of the most numerous duck species in the world and were named after the long central tail feathers males have. 

They can be recognized by their long necks and long and narrow wings. 

Males are mostly gray and have chocolate brown heads, white breasts, and a white stripe extending up the side of their necks. Females are patterned light brown and have gray-brown heads and shorter tails than males. 

Northern pintails have bluish bills they use to filter out seeds and insects. 

Males will often make soft “proop-proop” whistling calls while the females make low croaks and mallard-like quacks.

In North America, northern pintails breed in wet grassland, lakesides, and tundras of Canada, Alaska, and the Midwestern USA. 

They are one of the earliest nesting ducks there and their breeding season lasts from April to June; a female will lay 7-9 creamy eggs.  

When the winter comes, they move to sheltered estuaries, brackish marshes, and coastal lagoons of Southern USA, Mexico, Central, and South America.

They are very social birds outside the breeding season and will often mix with other ducks. 

Northern pintails feed by dabbling in shallow waters, consuming plants, aquatic insects, mollusks, and crustaceans.

Harlequin Duck

Harlequin Duck
  • Scientific Name: Histrionicus histrionicus
  • Lifespan: up to 20 years
  • Wingspan: 26 in
  • Beak Color: Blue-gray

Harlequin ducks are small sea ducks named after Harlequin, a character from an Italian comedy wearing a mask and an oddly painted costume. 

These ducks are also known as lords and ladies. 

Males have slate blue plumage with white stripes and chestnut sides during the breeding season; females have grayish-brown plumage. 

Harlequin ducks also have small pale blue-gray bills. To maintain a bond, pairs will often nod with their bills at one another, shake them from side to side, and dip between the nods. 

Harlequin ducks breed in fast streams of north-western and north-eastern North America, Greenland, Iceland, and eastern Russia. 

These ducks with blue beaks are migrants and will move to winter on rocky windswept shorelines of the Atlantic and Pacific Oceans. 

Such a lifestyle takes a toll on their bodies, as they end up with broken bones and skulls from being tossed around by the water. 

Harlequin ducks will make small flocks during winter. 

They are carnivores and have a diet consisting of insects, fish, and aquatic invertebrates. 

Harlequin ducks are very vocal and will often make cute mouse-like squeaks.


Greater Scaup

Greater Scaup
  • Scientific Name: Aythya marila
  • Lifespan: up to 20 years
  • Wingspan: 28-33 in
  • Beak Color: Dull blue with black tip

Greater scaups are medium-sized diving ducks known as “bluebills” in North America. 

They have rounded heads and yellow eyes. 

Males have black breasts, gray backs, and white sides, while the females are brown overall with white wing markings similar to those that males have. 

Greater scaups also have dull blue bills with black tips. 

In North America, they breed in shallow lakes and ponds of Northern Canada and Alaska and winter along the coasts of North America, shores of the Great Lakes, and in the Gulf of Mexico. 

Greater scaups are monogamous and females will lay 6-9 olive-brown eggs. 

During winter, they will form large groups consisting of hundreds and thousands of birds.

Greater scaups are omnivores and feed on insects, mollusks, crustaceans, plants, and seeds. 

They are great at diving and can go up to 23 feet below the surface. 

Identify them by males’ soft nasal courting whistles and females by their raspy “arr-arr” alarm calls.


Lesser Scaup

  • Scientific Name: Aythya affinis
  • Lifespan: up to 18 years
  • Wingspan:  27-31 in
  • Beak Color: Blue with black tip

Lesser scaups are small North American diving ducks. 

They are also known as “little bluebills” or “broadbills” because of their distinctive bills.

Identify males by their black and white plumage, iridescent black heads (green or purple in the right light), white sides, black rumps, black and white barred backs, and yellow eyes. 

Females have dark brown upperparts, white underparts, brown sides, and a white ring around their bills.

Lesser scaups have bluish beaks that are 1.4–1.7 inches long and have a small black “nail” at the tips.

They often form large flocks and inhabit lakes, ponds, and rivers.

They breed in inland lakes and marsh ponds in the tundra in northern parts of North America; typically from May to June and lay 9-11 eggs.

They will then migrate south to winter on lakes, rivers, sheltered coastal lagoons, and bays in western and southern parts of the USA, Mexico, and Central America.

Lesser scaups are the most widespread species of diving ducks in North America, with an estimated population of slightly under 4 million.

They are omnivores and have a diet consisting of insects, mollusks, invertebrates, aquatic plants, and seeds.

Lesser scaups are related to greater scaups but there are several differences between the species.

Lesser scaups are slightly lighter and shorter; greater scaups have more rounded heads and larger and wider beaks.

Females will often make high-pitched “purr” calls.

During summer these black and white ducks can be also seen in Colorado and Northern Texas.


White-headed Duck

White-headed Duck
  • Scientific Name: Oxyura leucocephala
  • Lifespan: n/a
  • Wingspan: 23.6-27.5 in
  • Beak Color: Bright blue

White-headed ducks are small diving ducks found in Europe, Africa, and Asia. 

They have long tails that they often hold cocked.

Male white-headed ducks have reddish-gray plumage, striking white faces, and black crowns that contrast well with their large blue bills. 

Females are gray-brown and have white faces and darker bills. 

White-headed ducks breed in lakes with open water and dense vegetation, in Europe (Spain), northern parts of Africa, and western and central parts of Asia.

These diving ducks are mainly quiet and do not fly that often; they will often swim away from danger rather than try to fly.

White-headed ducks are omnivores and have a diet consisting of plants, seeds, small fish, snails, and crabs. 

In the last decade, their numbers have been seriously dropping due to habitat loss and hunting; these blue-billed ducks are now listed as Endangered by the International Union for Conservation of Nature (IUCN).


Lake Duck

When the non-breeding season comes, their heads turn brown. 

Females have gray-brown plumage, white bellies, brown breasts, and yellow-brown heads and necks. 

Redheads breed in central and western parts of North America, and parts of Alaska, around wetlands with dense vegetation. 

They winter in southern USA, Mexico, and Central America, around reservoirs, lakes, wetlands, coastal marshes, estuaries, and bays. 

Recognize male redheads by distinctive wheeze “whe-ough” courting calls and females by their deeper “kur-kur” warning calls. 

These blue-billed ducks are parasites and will often lay their eggs in nests of mallards, northern pintails, ruddy ducks, and American wigeons for them to raise. 

They will often dive to grab underwater vegetation; redheads are omnivores and consume plants, mollusks, and insect larvae.


Baer’s Pochard

Named after a Prussian naturalist Karl Ernst von Baer, these ducks are also known as Siberian white-eye pochards or green-headed pochards. 

Baer’s pochards have steely blue-gray bills, dark gray heads, necks, and backs, reddish-white flanks, and bellies. 

Females and immatures have dark brown heads and dark eyes.

Although mostly quiet, they become vocal during their breeding season. 

Baer’s pochards are listed as Critically Endangered by the IUCN with some estimates claiming just 300-1,000 of these blue-billed birds in existence today. 

They are omnivores and feed on plants, mollusks, frogs, small fish, and insects. 


Tufted Duck

Tufted Duck
  • Scientific Name: Aythya fuligula
  • Lifespan: n/a

  • Scientific Name: Oxyura maccoa
  • Lifespan: n/a
  • Wingspan: n/a
  • Beak Color: Bright cobalt blue

Maccoa ducks are small stiff-tailed ducks found in Africa. 

They inhabit freshwater wetlands such as lakes, ponds, lagoons, and occasionally saline lakes of the eastern and southern parts of the continent. 

They breed from January to May, males are polygynous (they mate with multiple females), and do not help with nest building or raising the young. 

Females will lay from 5-12 eggs, occasionally in another duck’s nest. 

To move quicker in water, these ducks have legs that are set further back on their bodies; this can make them look awkward when walking out of water. 

Breeding male Maccoa ducks have conspicuous cobalt blue bills, black heads and throats, brownish underparts, and black rumps, tails, and feet. 

Non-breeding males and females have mostly dark brown plumage with white head stripes. 

Male Maccoa ducks will make short whistles and 2-3 seconds long “prr” sounds during their mating display; both sexes will make low grunts when threatened. 

Instead of flying away from danger, they prefer to dive and can stay underwater for over 20 seconds. 

Maccoa ducks are omnivores and consume plants, seeds, small fish, snails, crabs, and larvae. 

Due to ever-increasing pollution, habitat loss, and accidental capturing, these ducks are now listed as Endangered by the IUCN.
