White-Fronted Goose

White-Fronted Geese are medium-sized grey geese, identifiable by their distinctive white facial patch around the bill and contrasting black belly stripes. These geese, larger than a Mallard but smaller than a Mute Swan, feature orange legs, with variations in bill colour – pink for Siberian birds and orange for Greenland birds.

Their wingspan ranges from 130 to 165 cm, and they weigh between 1,900 to 2,500g.

Differences Between Male And Female White-Fronted Geese

Male and female White-Fronted Geese have similar appearance, sharing greyish-brown plumage with light grey breasts marked by darkish brown to black bars and blotches. However, males are typically larger.

Both sexes have pinkish bills and orange-coloured legs and feet.

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.

Unlike the Leach’s Petrel, their tails are square, not forked. When in flight, they are a sight to behold, fluttering just above the water with wings held high in a ‘V’ shape, their feet skimming the waves. These birds are social feeders, often seen in flocks, especially trailing behind ships in hopes of an easy meal.

Differences Between Male And Female Storm Petrels

Male and female Storm Petrels are quite similar in appearance, making it a challenge to differentiate between the two. Both share the same colouration and size, with a length of 14-18 cm and a wingspan of 36-39 cm.

Their plumage is a mix of brown, grey, black, and white, while their legs are a subtle brown.

Starling

Starlings are often mistaken for blackbirds due to their similar size. However, these birds are distinguished by their shorter tails, pointed heads, and triangular wings.

At a distance, Starlings may appear black, but a closer look reveals a glossy sheen with hints of purple and green. Their feathers are speckled, particularly visible in their brown winter plumage adorned with bright white spots.

Starlings are known for their confident walk and run on the ground, and their flight is characterised by its speed and directness.

Differences Between Male and Female Starlings

Male and female Starlings can be differentiated by subtle changes in their beak colour. While both sexes have yellow beaks, the male’s beak turns black during the winter. Additionally, the females tend to have a slightly duller hue in their plumage compared to the males.

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.

Black-Throated Divers are striking waterbirds, larger than Great Crested Grebes but smaller than Cormorants.

In summer, they display a beautiful black throat, a grey head, and neck, along with a distinctive black-and-white chequered back.

Come winter, their plumage transforms to dark grey above and white below, with a noticeable patch of white on the rear flanks.

Differences Between Male And Female Black-Throated Divers

The male and female Black-Throated Divers are visually similar, making it challenging to distinguish between them based on appearance alone.

Black Guillemot

Black Guillemots are easily recognisable, especially in summer, with their stark black and white feathers and striking red feet. They typically appear in smaller groups or individually all over rocky islets.

Found predominantly in western Scotland’s sea lochs and the northern and western isles, these birds also reside in Ireland, the Isle of Man, and some locations in Wales and England.

Differences Between Male And Female Black Guillemots

There’s little to distinguish males from females in the field, as both sexes don similar black summer plumage with prominent white wing patches. Their bill is black, and their feet are a vivid coral-red.

Black Grouse

Black Grouse are striking birds, with males showcasing an all-black plumage, contrasted by a distinctive red wattle above the eye and a white stripe along each wing in flight. Their notable feature is the lyre-shaped tail, which they fan out to display white under-tail feathers during courtship rituals.

Females, smaller in size, don a grey-brown plumage with a slightly notched tail, blending seamlessly into their natural habitat.

Differences Between Male And Female Black Grouse

Males are predominantly black with eye-catching white wing bars and red wattles above their eyes.

In contrast, females are grey-brown with a pattern of black barring, offering them excellent camouflage in the wild.

Coal Tit

Coal Tits are petite birds easily recognised by their agile movements and distinctive colouring. They sport a glossy black cap and bib contrasted sharply with their bright white face and throat. Their wings and tail feature striking black with bold white bars, while their underbellies are a soft grey, fading to a light yellowish hue at the breast.

These birds are well-adapted to cold climates, with a dense feathering that they can puff up to trap air for insulation.

Differences Between Male And Female Coal Tits

While both sexes of Coal Tits share the same vibrant white cheek patches and greyish underparts, subtle differences mark the males and females. Males boast a slightly darker grey on their backs and a more pronounced black on their heads, giving them a sharper contrast.

Females, on the other hand, have a lighter, brownish-grey back which makes their appearance slightly less contrasting than their male counterparts.

Black Redstarts captivate with their sleek black and fiery red plumage. Males are particularly striking, featuring a deep grey to black body contrasted by a vibrant red tail and rump, which they proudly display.

Differences Between Male and Female Black Redstarts
