Auks

Here's a list of all the UK Auks:

Razorbill

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.

Puffin

Puffins, belonging to the genus Fratercula, are small, charming seabirds with a distinct appearance. They have black or black and white plumage, a stout build, and large, colourfully hued beaks during the breeding season.

Their short wings are designed for swimming underwater. When flying, they beat their wings rapidly, giving them a distinctive flight pattern.

Differences Between Male And Female Puffins

Male and female Puffins are similar in size and colouration. However, males generally have slightly larger bodies and beaks. The gender differences are subtle and often not easily discernible.

Little Auk

Little Auks, resembling starlings in size, boast a distinctive black and white plumage. During flight, their dark underwings contrast starkly with their white underparts.

These birds are notable for their stubby black bill and short neck and tail, giving them a compact appearance. Their rapid wingbeats create a unique visual as they skim low over the sea’s surface.

Differences Between Male and Female Little Auks

Males and females are similar in appearance, both in their summer and winter plumages. However, upon closer inspection, females are slightly smaller and lighter than their male counterparts.

Guillemot

The Guillemot, a member of the auk species, is a distinctive seabird known for its summer breeding on land. It’s slightly bigger than the razorbill and sports a brown head and upper body with a contrasting white lower body.

In good light, you can discern its brown colouring, which often appears black from a distance. Notably, its head, neck, and long, slender black bill blend smoothly, and its short tail leaves its feet protruding in flight.

Differences Between Male And Female Guillemots

Males and females are similar in appearance, making it a challenge to distinguish them in the wild. Both genders share the characteristic brown and white plumage and sleek black bill, with subtle size differences.

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.
