Ducks

Here's a list of all the UK Ducks:

Quick Nav

Wigeon

Wigeons are medium-sized ducks, recognised by their round heads and relatively small bills. The males boast a striking appearance with their chestnut heads and necks, complemented by a yellow forehead, pink breast, and a grey body. What sets them apart in flight is their white underbellies and, for the males, a prominent white wing patch.

These ducks are a common sight, particularly in the UK, due to their significant wintering numbers.

Differences Between Male And Female Wigeons

Male Wigeons are easily distinguishable with their colourful plumage – a mix of chestnut, yellow, pink, and grey. The females, on the other hand, tend to have a more understated mottled brown or grey appearance, resembling female mallards but with a pointed tail.

Both sexes share a common feature – a small grey bill tipped with black.

Velvet Scoter

Velvet Scoters are remarkable for their bold, contrasting colours and robust build. Males are predominantly black with a distinctive white eye patch and a conspicuous white wing patch.

Their large, bulbous bill is a vivid yellow, adding a splash of colour to their otherwise dark plumage. Females, on the other hand, sport a more subdued brown colouration with paler head patches and white wing markings.

Both sexes showcase a hefty body and long wings, measuring around 51 to 58 cm in length with a wingspan stretching between 86 to 99 cm.

Differences Between Male and Female Velvet Scoters

Distinguishing male and female Velvet Scoters is quite straightforward.

Males boast a glossy black plumage with a yellow-edged bill and a unique white mark near the eye.

Females, however, are cloaked in dark brown with less pronounced white head patches and a darker bill. During flight, both genders reveal the characteristic white wing patches, a key identification feature of this species.

Tufted Duck

The Tufted Duck is a charming, medium-sized diving bird, slightly smaller than the familiar Mallard. Recognisable by their bold black and white colouring, the males boast a sleek black head, neck, breast, and back, contrasted by striking white sides.

Notably, both sexes flaunt a unique feather tuft at the back of their heads, with males displaying a more pronounced version. They have golden-yellow eyes and a small crest, with a notable white stripe across the wing in flight. Measuring 40-47 cm in length with a wingspan of 67-73 cm, they are a frequent sight across the UK’s water bodies.

Differences Between Male And Female Tufted Ducks

Males are distinguished by their stark black and white plumage and a blue-grey bill. In contrast, females wear a more subdued brown attire with paler flanks, occasionally showing white around the bill base. While the male is mostly silent, the female’s vocalisation is a distinctive, harsh “karr”, primarily heard in flight.

Teal

Teals, the smallest of dabbling ducks, exhibit distinct colours and patterns.

Male teals boast a chestnut head with a striking green patch near the eye, a speckled chest, and grey sides, highlighted by a yellow-tailed border. In contrast, female teals display a mottled brown plumage.

Both sexes share a notable feature: vivid green wing patches visible during flight. These ducks are commonly found in UK’s marshlands and exhibit a blend of colours that make them easily distinguishable from other duck species.

Differences Between Male And Female Teals

Male and female teals can be differentiated by their distinct colouration. The males, or drakes, are characterised by their grey bodies, speckled breasts, and the notable chestnut head with a green eye patch.

Females, or hens, are predominantly mottled brown, which offers camouflage in their natural habitat. However, both genders share the bright green wing patch, a key identifying feature, especially visible during flight.

Learn more

Scaup

Scaups are striking diving ducks, often confused with Tufted Ducks.

The males boast a splendid black head, shoulders, and breast, contrasted with white flanks and a grey back. Their black tails add to their distinct appearance. Females, meanwhile, wear a brown plumage adorned with prominent white patches near their bill.

When these birds take flight, they reveal white stripes along their wing’s back edge.

Differences Between Male And Female Scaups

Male and female Scaups differ notably. Males display a glossy greenish-black head, lacking the crest seen in Tufted Ducks, and have a rounder shape.

Their white flanks and grey backs set them apart. Females are brown but can be easily identified by the bold white patch around the bill base, more striking than in any female Tufted Duck. Juvenile Scaups, usually dark brown, might exhibit a subtle white bill patch.

Smew

Smews are distinctive ducks, making them a fascinating subject for observation.

Male smews are particularly striking with their bold black-and-white plumage, which has earned them the nickname ‘panda ducks’. They exhibit a ‘cracked ice’ appearance, predominantly white with a stark black back, and a distinctive black mask. Their flight reveals contrasting black and white wings.

Female smews, also known as ‘redheads’, have a more subdued grey body with a chestnut head and a white cheek patch. In flight, they display notable oval white wing-patches.

Young males and females can be easily mixed up with other species, but the smew’s hooked, serrated bill sets it apart, aiding in its fish-catching endeavours. Measuring about 38-44 cm in length with a wingspan of 55-69 cm, they are relatively small yet robust.

Differences Between Male And Female Smews

Distinguishing between male and female smews is quite straightforward. Males are predominantly white with black markings, presenting a stark contrast, while females sport a grey plumage with a reddish-brown head.

Both genders share the characteristic white cheek patch, but it’s the male’s striking black-and-white combination that truly sets them apart.

Learn more

Slavonian Grebe

Slavonian Grebes are remarkable for their golden ear tufts, a feature that has earned them the nickname ‘horned grebe’ in America. These birds, comparable in size to a moorhen, boast a length of about 31-36 cm and a wingspan of 62cm.

Weighing around 410g, they have a distinctive appearance, especially in their breeding plumage, which includes golden ‘horns’, black cheeks, and a vibrant red neck and flanks. In contrast, their winter attire is a more subdued black and white, blending seamlessly with other grebe species.

Differences Between Male And Female Slavonian Grebes

Male and female Slavonian Grebes share similar plumage, with males being slightly larger and more vividly coloured. However, these differences are subtle, making it a bit of a challenge to distinguish between the two.

Shoveler

Shovelers are easily recognised by their large, spoon-shaped bills, perfect for surface feeding. The males boast a striking appearance with dark green heads, contrasting white breasts, and chestnut sides. Females, on the other hand, display a mottled brown plumage.

Both genders exhibit distinctive light blue and green patches on their wings when in flight. These ducks typically measure 44-52cm in length with a wingspan of 70-84cm.

Differences Between Male And Female Shovelers

During the breeding season, male Shovelers are particularly colourful with their dark green heads and bright white breasts, accompanied by orange-brown sides. Females, in contrast, are more subtly coloured with mottled brown feathers.

Interestingly, male Shovelers undergo a transformation outside the breeding season, adopting a more camouflaged, mottled brown ‘eclipse’ plumage similar to the females.

Shelduck

Shelducks stand out with their vibrant and unique appearance. They’re larger than your typical mallard but smaller than a goose. These birds boast a dark green head and neck, complemented by a chestnut belly stripe. Their red bill adds a dash of bright colour, making them easily identifiable.

Differences Between Male And Female Shelducks

While male and female Shelducks share similar colouration, there are subtle differences. The male Shelduck, especially during the breeding season, displays more vivid colours. His bill turns a brighter red and features a noticeable knob on the forehead.

Females, on the other hand, are generally smaller and have distinct white facial markings.
