The splash came from my right. A Neotropic Cormorant ran across the water, flapping its wings, trying to gain lift. It was coming along the shoreline and would pass our boat as we floated on the Rio Sararé in the Pantanal. They typically need to run into the wind, but this morning it was calm, and surprisingly it had taken off by coming right toward us.
These cormorants are compact, dense, and look like torpedoes. They are pursuit hunters, chasing down fish underwater. Their body, neck, and head are all hydrodynamic for the least drag possible. Their feet are set well back on their body; this makes them ideal for propulsion underwater but not the best for walking around on land. All four of their toes are connected by webbing, totipalmate feet, where a duck or goose only has three toes webbed.
I’d brought my GoPro on this trip in the hopes of doing some underwater filming. But unfortunately, the water here in the Pantanal of Brazil is high in tannins and organic matter, so nothing is visible a few feet out. So, no luck, but the athleticism of this bird taking off was a treat to watch.

To take off, the bird pushed hard down with both feet like it was trying to launch from the water’s surface. At the same time, it flapped its wings, the outer primaries hitting the water, helping to lift its body. It then drew both feet forward as far as possible and pushed hard on the water, flapping again. In essence, it was hopping as fast as it could while smacking the water with its wings. Finally, it gained enough altitude to fold back its feet and move just to wing beats.

The cormorant disappeared down the river. Neotropic Cormorants are smaller than the widespread Double-crested Cormorant of Northern America. They live all through Latin America and even extend into Southeast Texas. This is one of the most adaptable birds in the Western Hemisphere, ranging from sea level to some Andean Lakes at 5,000 meters.

Neotropics and Double-crested look much alike, and the size difference is often impossible to tell. Double-cresteds don’t occur in South America. The best characteristic to separate them is to look at the profile of their gular pouch, the yellowish area behind the bill, and at the top of their neck. On an adult Neotropic, this structure looks like a horizontal “V” with the bottom pointed backward and is less than 50% of the rest of the head. The V also has a thin white border along the back edge. In the Double-crested, the pouch is bigger and rounded rather than “V” shaped.
Farther down the river, a cormorant sat on a branch hanging over the river. Its webbed feet curled around the twig as the combination swayed slightly. In this morning sun, the feathers had a sheen to them. It didn’t fly as we cruised by.

The Neotropic cormorant is common here in New Mexico and breeds here in the summer. One of my fav birds to watch for.
So cool. I hadn’t realized they bred in New Mexico. I’d seen them in Mexico; such a great bird. Thanks for reading this. Have fun birding.
Great pics of Cormorant
