Freshwater ponds and swamps with thick vegetation, especially where there are large trees.


Breeds near Atlantic and Gulf coasts from North Carolina to Texas, in Florida, and in Mississippi Valley north to southern Missouri and Kentucky. Winters along Gulf Coast north to South Carolina. Also in tropical America.


Also known as the "Snakebird," the Anhinga often swims with its body submerged and only its head and long slender neck visible above the water. Its long, dagger-shaped, serrated bill is ideally suited for catching fish, which it stabs and then flips into the air and gulps down headfirst. Cormorants and Anhingas lack oil glands with which to preen and so must perch with their wings half open to dry them in the sun. Anhingas often soar in circles high overhead.


3-5 chalky blue eggs in a nest of sticks lined with fresh green leaves and built in trees. Often nests in colonies of Double-crested Cormorants.
