Shag
Shags are goose-sized, dark, long-necked birds similar to cormorants but smaller and generally slimmer with a characteristic steep forehead. In the breeding season adults develop a dark glossy green plumage and prominent crest on the front of their head.
In the UK they breed on coastal sites, mainly in the north and west. Over half their population is found at fewer than 10 sites, making them an Amber List species. Shags usually stay within 100-200km of their breeding grounds.
Nests are in coastal colonies on ledges and sea cliffs, or among large boulders.
Fish and occasionally crustacea and molluscs.
Grunts and croaks during the breeding season; generally silent in winter.
All year round on the Bass Rock, Isle of May, Fidra and Craigleith.
