Gannet
Morus bassanus (Northern gannet)
Adults are large and bright white with black wingtips. They are distinctively shaped with a long neck and long pointed beak, long pointed tail, and long pointed wings. At sea they flap and then glide low over the water, often travelling in small groups. They feed by flying high and circling before plunging into the sea. It breeds in significant numbers at only a few localities and so is an Amber List species.

The Gannet's World
There are currently estimated to be over 150,000 Atlantic gannets on the Bass Rock, making it the world's biggest single rock gannetry and, in the words of David Attenborough "one of the Twelve Wildlife Wonders of the World". Go to "A Bit of History" to find out about the Bass Rock and its Gannets from author, scientist and world authority on gannet behaviour, Dr Bryan Nelson.
