Where Does the Anhinga Live?

The Anhinga is a native specialist of the warmer regions of the Americas, thriving in both the Northern and Southern Hemispheres. Its core range begins in the southeastern United States, particularly Florida and the Gulf Coast, and extends through Mexico and Central America into the tropical heart of South America as far south as Argentina. While they are year-round residents in most of their range, some northern populations in the U.S. may move southward during particularly cold winters.

Behavior

The Anhinga is famously known as the 'Snakebird' because of its habit of swimming with its entire body submerged, leaving only its long, slender neck and head visible above the water. This gives the appearance of a snake moving through the reeds. Unlike many other water birds, Anhingas do not have waterproof feathers. While this makes them less buoyant and better divers, it also means they get waterlogged easily.

To dry off after a hunt, they spend hours perched on branches with their wings spread wide to catch the sun's rays. This iconic 'sunning' posture is a common sight along lake edges. They are solitary hunters but often share nesting colonies with other wading birds like egrets and herons. Despite their somewhat prehistoric appearance, they are graceful fliers and can often be seen soaring high on thermal air currents like hawks.

Camera Tips

To capture high-quality footage of an Anhinga, your best bet is to locate their favorite drying perch rather than trying to film them in the water. Look for dead branches or logs that extend into the water in sunny, wind-protected areas. Mount your camera on a nearby tree or post at a height of 3-5 feet, angled slightly downward toward the perch. Because Anhingas often return to the same spot daily to dry their wings, a fixed camera position is highly effective.

Since these birds are active during the day, you don't need to worry about infrared range, but you should prioritize a camera with a high trigger speed. Anhingas can be very still while sunning, so setting your camera to 'Video Mode' or 'Burst Mode' is essential to capture the moments when they stretch their necks, preen their feathers, or suddenly dive into the water. If your camera supports it, a time-lapse setting during the mid-morning hours can produce a beautiful sequence of the drying process.

If you have a backyard pond, you can attract them by ensuring there are 'loafing' spots—submerged logs that break the surface are ideal. Avoid placing cameras too close to active nests, as this can stress the birds; instead, focus on the edges of the water where they forage. Anhingas are visual hunters, so keeping the water surface clear of heavy debris in front of your camera's field of view will help you catch clear shots of their 'snake-neck' swimming style.

Frequently Asked Questions

Anhingas are strictly diurnal, meaning they are active during the day. They are most frequently seen hunting at dawn and dusk, but the best time to spot them on camera is mid-morning, between 9 AM and 12 PM, when they are most likely to be perched and drying their wings in the sun.
If you have a backyard pond or live near a canal, you can attract Anhingas by providing 'sunning logs' or branches that hang low over the water. They require these perches to dry their non-waterproof feathers after hunting. Maintaining a healthy population of small fish in the water will also keep them coming back.
Anhingas are specialized hunters that primarily eat fish. Unlike ducks, they use their sharp, needle-like bills to spear fish through the side. They then bring the fish to the surface, toss it in the air, and swallow it headfirst. They also occasionally eat crayfish, shrimp, and aquatic insects.
Yes, in the southeastern United States, Anhingas are very common in suburban areas that feature golf course ponds, drainage canals, or decorative neighborhood lakes. As long as there is fresh water and plenty of fish, they adapt well to human-altered landscapes.
While they look similar, the easiest way to tell them apart is the bill: Anhingas have a straight, pointed, dagger-like bill, while Cormorants have a hooked tip. Additionally, Anhingas have much longer, fan-shaped tails and silver-white patches on their wings that Cormorants lack.
