A bird of the tropical waterways of Central and South America, the Neotropic Cormorant reaches the upper limits of its range in Texas and occasionally, the Great Plains. Although it superficially resembles North America's other freshwater cormorant, the Double-crested Cormorant, the Neotropic Cormorant stands apart in various aspects of behavior, as well as range.
The Neotropic Cormorant is the only cormorant known to plunge-dive into water to catch fish. Unlike gannets and boobies, it does not dive from great heights, restricting its dives to less than a half-meter (1.75 feet) over the water. It is not particularly successful with this technique, catching a fish only once in every six to ten plunges.
In Mexico, Neotropic Cormorants reportedly often fish cooperatively, forming a line across swift-flowing streams and striking the surface with their wings, causing fish to flee, whereupon the cormorants dive and pursue them.Bibliographic Citation
