Ynghylch

Shags are large, dark waterbirds, a little bit smaller than cormorants. They feed on fish, which they catch with their long, hook-tipped bills while swimming underwater. Shags nest on cliffs around our coasts, but are very rarely seen inland. They can often be spotted perched on a rock or bank with their wings held out. In this stance, they are able to dry their feathers off which are not waterproof.
