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.
Learn moreTufted 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.
Learn moreStorm Petrel

Storm Petrels are charmingly petite seabirds, slightly larger than sparrows, with a distinct appearance. They exhibit a predominantly black colouration, contrasted by a striking white rump.
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.
Learn moreSlavonian 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.

When in flight, one can observe grey wedges on their wingtips and a forked tail. These birds are medium-sized and slender with long, pointed wings, making them a standout species in the UK, especially in nature reserves where they thrive.
Differences Between Male And Female Sandwich Terns
Interestingly, male and female Sandwich Terns share a similar appearance. Both genders boast the same colour patterns, with breeding adults showcasing a pale grey upper body, white underparts, and a black crest.
The key identifier when looking for Sandwich Terns, is their black bill with a yellow tip. The only notable difference is their size, with males generally being slightly larger than females.
Learn moreRazorbill

Razorbills are medium-sized seabirds, easily identified by their black upperparts and white underbelly. A defining feature is their thick, black beak, marked by a distinctive white line.
Measuring 37-39 cm in length with a wingspan of 63-67cm, they’re a sight to behold on the UK’s rocky coasts.
Differences Between Male And Female Razorbills
While male and female Razorbills are similar in plumage, males are generally larger. However, this size difference is subtle and can be challenging to discern in the field.
