Phalacrocorax graadus
A common resident ; perhaps even more numerous than the Cormorant.
There are small colonies on St. Margaret's Island, and on the Channel side of Caldy Island, near Tenby; on Skomer and Ramsey Islands, and at various places on the coast. Mr. Dix, who paid a visit to the Stack Rocks to see the enormous numbers of Guillemots that frequent them in the summer, states that on the west side of the Great Stack is a cave, in which Shags breed in safety, as it is perfectly inaccessible.
