A large, glossy, black, underwater swimmer that dives to find its prey and often swims with just its neck and head visible. It has a long tail and neck, a yellow-orange throat patch, and can appear to have a green sheen in certain lighting. The “double-crest” refers to the crests that grow during breeding season but are often hard to see. These birds hunt in packs. Like the Anhinga, the Cormorant lacks oil glands, making them not fully waterproof. They can often be seen with their wings outstretched allowing them to dry. Despite years of persecution by fisherman who viewed them as competitors, the Cormorant population is currently increasing.

Common
Diurnal
Mainly eats fish, but will sometimes also eat amphibians, crustaceans and insects.
Double-breasted Cormorants can be found in small and large groups both on the breeding grounds, and during the winter. They breed in colonies and often feed in large flocks. They also migrate in large groups. Double-crested cormorants feed during the day by diving for fish. After diving, cormorants look for an elevated spot to perch with their wings outspread. This is most likely done to dry out the feathers.
