NEOTROPIC CORMORANT
(Phalacrocorax brasilianus)
eBird offers this description of the Neotropic Cormorant: Black body. Immatures have dark brown breast. Orange facial skin comes to a point and is bordered by thin white line. Smaller, longer-tailed and shorter-legged than Double-crested Cormorant. Dives underwater to capture fish. Often perches with spread wings to dry them out. Most widespread species of cormorant from Mexico south. In U.S., seen mostly in Texas. All About Birds gives this basic description of the Neotropic Cormorant: A nearly all-black waterbird with a snaky neck, the Neotropic Cormorant occurs in sheltered waters of southern U.S. states, the Caribbean, and Latin America. It is smaller and longer-tailed than other cormorants, but otherwise looks very similar to the Double-crested Cormorant, and the two species often flock together. Unlike its larger cousin, it sometimes plunge-dives for fish from a few feet above the water, almost like a booby, though it dives mostly as it paddles along the water’s surface, catching fish as it darts through the water.
I saw my first Neotropic Cormorant early on the morning of June 18, 2020. I was headed to my doctor’s office when, crossing the Common Street Bridge in New Braunfels, Texas, I caught a glimpse of two large, dark birds in the Guadalupe River. I pulled over, got my camera ready, and walked slowly toward them. They turned out to be two Neotropic Cormorants, one breeding adult and one juvenile. A few minutes later, a second juvenile flew to a nearby rock and dried its wings. All three birds were willing subjects for my camera!
“Cool Facts” About The Neotropic Cormorant From All About Birds…
- After a population drop in the 1960s, possibly due to the effects of DDT, the Neotropic Cormorant has rebounded and expanded its range rapidly in the United States. The species now nests in new areas including Arizona, New Mexico, Arkansas, Oklahoma, Florida, and Louisiana. In some places where their ranges meet, Neotropic and Double-crested Cormorant have nested together in mixed pairs and have produced hybrid offspring.
- Neotropic Cormorant’s calls are sometimes likened to piglike grunts. In Mexico and other Spanish-speaking countries, local names that allude to this call include “pig duck” (pato cerdo, pato puerco), “dirty duck” (pato chancho), and “oinking duck (pato gruñón)!
- The Neotropic Cormorant is the only cormorant that plunges from midair into water to catch fish. Unlike gannets and boobies, it does not dive from great heights, restricting its dives to less than a 2 feet over the water.
- In Mexico, Neotropic Cormorants reportedly fish cooperatively. The birds form a line across swift-flowing streams and strike the surface with their wings. This scares fish into motion, whereupon the cormorants dive and pursue them.
- The oldest recorded Neotropic Cormorant was at least 11 years, 9 months old when it was found in Louisiana.
