Cormorants are mostly seen in groups or even in large flocks while Anhinga birds are seen by themselves or a mate (occasionally in a small flock but spread-out). The Cormorants often travel with White Pelicans to hunt fish cooperatively.
The Cormorants have a chunky thick body and a slight hook to the end of their bill. Anhingas have a thinner body and have a thin sword-like bill. Female Anhingas have a light brown ruff of feathers on the underside of their neck. Both birds are diving birds and their appearance in the water when surfacing is snake-like. Both bird must spread their wings to dry them after diving. Both are great fliers and perch in water-front trees.
The Anhingas are considered to be tropical birds and are most often here in Florida or very near. The Cormorants can be found in many places throughout the United States.
