Here's a list of all the UK Large Brown Bird:

Quick Nav

White-Tailed Eagle

White-Tailed Eagles, the UK’s largest birds of prey, are majestic creatures with a distinctive appearance. These birds boast broad wings with ‘fingered’ ends and a wedge-shaped tail. Adults are recognisable by their brown body plumage, pale head and neck, which may appear almost white in older birds, and their signature white tail feathers.

Look for their yellow beaks and watch for their unique flight pattern, where their head protrudes, creating an imposing silhouette against the sky.

Differences Between Male And Female White-Tailed Eagles

Males and females can be tricky to distinguish, but generally, females are slightly larger. Both genders share similar plumage, but keen observers might note subtle differences in their size and wingspan, with females typically boasting a more robust frame.

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.

Whimbrel

The Whimbrel is a large wading bird that boasts long legs. It has a distinctive long bill that curves slightly near the tip.

Brown-coloured above and white below, it displays a white ‘V’ shape up its back in flight. Notably, it breeds exclusively in the northern parts of Scotland in the UK.

Identified by a dark crown, a pale stripe down the middle, and a dark eyestripe, the Whimbrel is slightly smaller than its close relative, the curlew. Its wingspan ranges from 71 to 81cm, and it weighs between 270-450g.

Differences Between Male And Female Whimbrels

Sexual dimorphism in Whimbrels is not readily apparent in external characteristics. Both males and females share similar plumage and physical features. The key distinctions lie in their behaviour, vocalisations, and reproductive roles rather than visual traits.

Tundra Bean Goose

Tundra Bean Geese are notable for their darker, browner shades compared to other grey geese species. These geese feature striking orange legs, a darker head and neck, and a bill typically showcasing a smaller yellow-orange patch.

They are generally smaller and sturdier than the Taiga Bean Goose, with a more compact body and a relatively shorter neck.

Differences Between Male And Female Tundra Bean Geese

While both genders exhibit similar plumage, males are slightly heavier than females. The male Tundra Bean Goose averages around 3.2 kg, while females tend to weigh about 2.84 kg. This subtle difference in size is one of the few distinguishing features between the sexes.

Taiga Bean Goose

The Taiga Bean Goose stands out in the UK for its distinct, darker brown plumage compared to other ‘grey geese’. It’s recognised by its orange legs, a darker head and neck, and a noticeable yellow-orange patch covering more than half of its bill.

Differences Between Male and Female Sooty Shearwaters

Typically, male and female Sooty Shearwaters are similar in appearance, making it challenging to distinguish between them based solely on plumage. Both sexes share the same dark colouration and physical features.

However, subtle differences in size or behaviour during mating and nesting periods might offer clues for differentiation.
