Razorbill vs Little Auk

In short

The Razorbill and Little Auk are both members of the Alcidae family, but they can be distinguished by their size and bill shape. The Razorbill is larger with a distinctively thick, blunt bill, while the Little Auk is smaller with a short, stubby bill. Both species are black and white, but their size and bill differences are key in the field.

Identification tips

1. Size and Bill: Look for the larger size and thick, blunt bill of the Razorbill compared to the smaller, stubby-billed Little Auk. 2. Habitat: Consider the location; Razorbills are more coastal, while Little Auks are often further north. 3. Vocalizations: Listen for the Razorbill's low calls versus the Little Auk's high-pitched chatter.

Size

The Razorbill is significantly larger than the Little Auk, which is one of the smallest auks.

Plumage

Both species have black upperparts and white underparts, but the Razorbill's larger size and more robust appearance help differentiate it from the smaller, more compact Little Auk.

Behaviour

Both species are often seen swimming and diving, but the Razorbill may be more likely to be seen in slightly larger groups compared to the typically smaller flocks of Little Auks.

Habitat

Razorbills are often found along rocky coasts and islands in the North Atlantic, while Little Auks are more associated with Arctic waters and are often seen further north.

Voice

The Razorbill has a low, guttural call, while the Little Auk produces a high-pitched, chattering call. These vocal differences can be useful in identifying them when visual cues are insufficient.
