Neotropic Cormorant


IUCN Conservation Status: Least Concern

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.

Cool Facts

  • 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.



Various wetlands, including fresh, brackish, and saltwater habitats. Nests and roosts mostly in trees, but also on cliffs and human-made structures.



Small fish and shrimp.

Least Concern

In the 1960s, Neotropic Cormorant populations declined severely in Texas; since then, these populations have shown a general trend toward growth. The cause of the declines is not conclusively understood.
