Shearwaters earned their name by their ability to cut - or shear - the water with their wings, although until recently they were known as 'muttonbirds'. This name was given to them by early European settlers, who killed the birds for food and found that their flesh tasted like mutton.
After feeding, cormorants need to dry their wings. They do not have oil in their skin to protect their feathers from getting wet, like ducks and othe water birds do. Cormorants find a perch and stretch their wings out until they are dry. Double-crested Cormorants often associate with other birds.uring breeding season, males have two curly black crests on their heads. Cormorants are water birds, and are found at lakes, rivers, streams, marshes, bays, and coasts. They are great swimmers and divers, as well as good flyers. Double-crested Cormorants usually travel, feed, and roost in groups.
