Understanding the Cormorant: A Large Waterbird of North America

The Cormorant is a large, dark waterbird characterized by its long, hooked bill and slender neck, reaching 27 inches in length with a wingspan of up to 50 inches. These birds possess a distinctive pale throat and chest that darkens further down, with entirely black plumage and small white plumes during breeding. Preferring marine and inland waters, Cormorants feed during the day by swimming and diving for fish and other aquatic prey. While they are protected by law in certain regions, they can be seen as pests by some due to their impact on aquaculture.
