Great Cormorant

Crossley ID Guide

Plenty of these in the Ouse Valley. They nest colonially on a tiny island in a small lake made by the owner of a local farm. The vegetation has been ruined through shear numbers. The Great Cormorant, Phalacrocorax carbo, is not to be confused (but often is) with the Shag, most notably by Christopher Isherwood in his poem The Common Cormorant.
