How to identify

The Cormorant is a large, black waterbird whose size and colour make it very visible. With a reptilian neck, it has an almost prehistoric appearance. It is often seen standing with its wings held out to dry. Cormorants are supreme fishers which can bring them into conflict with fisherman and has seen them persecuted in the past. The UK holds internationally significant wintering numbers of cormorants.

These familiar fish-eating waterbirds are a common sight on both inland freshwater and along our coasts. The similarly looking, sea-faring Shag can confuse some of the most experienced birders on a coastal cliff. In the breeding season, Cormorants have white patches near the base of their beaks and on their thighs. They’re also a stockier bird than the slender Shag – the latter also sports a mohican-like crest during breeding season.

Did you know?

Despite being an agile underwater hunter, its feathers aren’t waterproof. In fact, wet feathers help this species to move quicker when on the prowl, reducing the bird’s buoyancy as it darts through the depths.

Where and when to see them

Difficult rating - Easy

From coastal cliffs to city centre canals, a Cormorant can be seen almost anywhere where there’s water! Did you know there are actually fewer Cormorants than there are Shags in the UK? But their more varied habitats mean that you’ve likely had more close encounters with Cormorants.
