Cormorants swim with their bills angled upward. Flocks often fly in a V formation. They can often be seen resting with their wings open drying. They nest in colonies in Cypress trees and Mangroves.
They live on the coasts and near large bodies of inland water. Florida has a resident breeding population and there are numerous migrants from northern U.S. from November through April.
