Generally a smaller bird than the Great Northern Diver. In winter it is mostly black and white. In breeding plumage it has a grey head and neck, a wide black throat patch and white blocking on its back.

It can be found in north-west Scotland during the breeding season. Birds spend the winter on the coast.

It breeds on clear, fish-holding freshwater lakes, and builds its nests on small islets near the waterline.

Black-throated Divers are often gregarious in winter.

Amber status. Up to 250 pairs breed in the UK, and about 560 birds over-winter here.
