These birds consume fish, shrimp, frogs, and insect larvae such as dragonfly nymphs. They pursue prey visually, diving and swimming after it, catching it with their beak.
Look for Neotropic Cormorants in fish farms, ponds, lakes, reservoirs, rivers, inlets, and bays.
Neotropic Cormorants spend a lot of time on land, resting or drying their wings. Their plumage becomes wet, reducing their buoyancy and allowing them to move fast underwater and seize prey.
