Double-crested Cormorant (Phalacrocorax auritus) Science Article 4
The Double-crested Cormorant Phalacrocorax auritus has been protected by the Migratory Bird Treaty Act since 1972, as a result of a bilateral treaty with Mexico. Since that time, the U.S. Fish and Wildlife Service has had authority for cormorant management and conservation. From the late 1970s to the present, Double-crested Cormorants experienced dramatic population growth.
