You can often see the cormorants sitting on top of pilings holding their wings out to dry. The cormorant dives from the surface and swims around looking for prey. It dives to depths of 5 to 25 feet below the surface and stays under from 30 to 70 seconds. Sometimes you can see it surface with its catch's tail still sticking out of its mouth. It also eats crustaceans such as crabs, shrimp, and crayfish.
Cormorants nest in colonies.
Both the males and females build the nests which take about 4 days to build. Old nests may be used for 4 years. Nests are built in trees out of sticks and weed stems and are lined with leafy twigs and grass. Nests built on rocks are often made of seaweeds and trash gathered at the water's edge or in diving. Cormorants add objects like feathers and twigs of evergreen.
