Behavior

The Neotropic Cormorant is a highly social and masterfully adapted waterbird. Unlike many other aquatic species, its feathers are not entirely waterproof; while this might seem like a disadvantage, it actually allows the bird to sink more easily and maneuver with incredible speed underwater. This physical trait leads to their most iconic behavior: perched on a branch or pier with wings spread wide to dry in the sun and wind.

These birds are gregarious hunters, often seen in small groups or occasionally in large flocks where they may engage in 'communal fishing,' driving schools of fish into shallower water. In suburban settings, they are remarkably tolerant of human presence, frequently utilizing backyard boat docks and fence posts as vantage points. They are quieter than many other waterbirds, though they may emit low, pig-like grunts when at their nesting colonies.

Camera Tips

To capture the best footage of a Neotropic Cormorant, focus your camera placement on 'drying stations' rather than the water itself. These birds have favorite perches—usually a semi-submerged log, a low-hanging branch over water, or a private dock—where they spend hours drying their wings. Set your camera at a slight side-angle to these perches to capture the full wing extension, which provides a dramatic and educational silhouette. Aim for a height of 3 to 5 feet above the water level to get a natural, eye-level perspective.

Because cormorants have dark, iridescent plumage, they can be difficult for AI cameras to expose correctly, often appearing as a black silhouette. If your camera allows for exposure adjustments, try a slight negative compensation to preserve the detail in their feathers, especially in the bright midday sun. If you are placing a camera near a backyard pond, avoid using bait; instead, ensure there is a sturdy, horizontal branch or post at the water’s edge, as this is the best 'natural lure' for this species.

Action shots of Neotropic Cormorants diving or surfacing are exhilarating but require fast trigger speeds. Set your camera to 'Burst Mode' or high-frequency photo capture to catch the moment they emerge from the water with a fish. Since they are most active during the morning and late afternoon, ensure your camera's PIR sensor is sensitive enough to trigger in the softer light of dawn and dusk. In the winter months, look for them near spillways or areas where water remains open and moving, as fish tend to congregate there.

Finally, consider the background. Because these birds are dark, a background with lighter reeds, water reflections, or green foliage will help the bird 'pop' in the frame. Avoid pointing the camera directly toward the sun (south-facing in the northern hemisphere) to prevent lens flare and washed-out images during their peak activity hours.

Frequently Asked Questions

The Neotropic Cormorant is smaller with a much longer tail relative to its body. The best clue is the yellow-orange throat pouch: in Neotropic Cormorants, it forms a sharp, pointed 'V' shape at the base, whereas in Double-crested Cormorants, the pouch is larger and more rounded.

Their feathers are not fully waterproof, which helps them dive deeper without air bubbles floating them back up. After fishing, they must spread their wings to dry them out in the sun to maintain body temperature and flight ability.

They are diurnal, meaning they are active during the day. You will see them most frequently during the 'golden hours' of early morning and late afternoon when they are actively foraging for breakfast or a final meal before roosting.

Yes, if your backyard pond has small fish like goldfish or koi, a Neotropic Cormorant may stop by for a meal. They are excellent divers and can easily navigate small suburban water features.

Very much so! They are one of the most adaptable waterbirds in the Americas and are frequently found in golf course ponds, park lakes, and residential retention basins throughout the southern US and Central/South America.
