How to identify an anhinga
The anhinga is a study in long, thin lines. It has a slender black body, a snaky neck, a long fan-shaped tail, and a sharply pointed dagger of a bill — straight and unhooked. Males are glossy black; females and young birds wear a warm tan neck and chest. On the wings you'll see silvery-white streaks and patches, like frost painted along the shoulders. Perched, it's often frozen in that wings-out crucifix pose, soaking up sun. The long tail, by the way, is why old-timers call it the “water turkey.”
The single most useful field mark is the bill. The anhinga's is a straight spear — perfect for impaling fish. The very similar double-crested cormorant has a stout bill with a hooked tip for grabbing. Get the bill and you've got the bird.
Why it dries its wings
Here's the anhinga's strange genius. Most water birds carry waterproofing oil in their feathers. The anhinga doesn't — at least not much — and that's on purpose. Soggy, non-buoyant feathers let it sink low and slip underwater almost silently to hunt, instead of bobbing on top like a cork. The catch is that after a swim it's genuinely waterlogged and chilled, so it climbs out, finds a sunny snag, and spreads those wings to dry and warm up. That iconic spread-wing silhouette over a quiet creek isn't showing off — it's the bird literally hanging itself out to dry before it can fly well again.
How the snakebird hunts
Underwater, the anhinga is a patient ambush hunter. It swims with its body submerged and only that long neck periscoped up, which is exactly where the “snakebird” name comes from — from a distance it really does look like a water snake gliding along. When a fish swims close, a hinge in the neck lets it shoot the head forward and spear the prey on its dagger bill. Then it surfaces, flips the fish off the bill and into the air, and swallows it head-first. It's a remarkable thing to watch from a quiet boat in the Ten Thousand Islands.

Where to see anhingas near Naples & Marco
Anhingas love calm, sheltered water — the kind you find tucked inside the mangrove creeks and along the quiet shorelines of Rookery Bay and the back bays of the Ten Thousand Islands. Look for them perched on dead mangrove snags and oyster-bar pilings, wings out, catching the morning sun. They're here year-round, and they're one of the easier birds to get a long, clear look at because they sit so still while drying. Our dolphin & wildlife tours idle through that quiet backwater habitat, and the wildlife-by-season guide rounds out what else you'll see.
From the Helm: Anhinga-watching in the mangrove tunnels off the Marco River
Before anyone on deck spots the snakebird itself, our captains are watching the water, not the bird. In the skinny mangrove tunnels off the Marco River, past the no-wake stretch by Isles of Capri, the surface has to go dead still — no wind ripple, no wake rolling off another boat — before an anhinga will settle in long enough to hunt. We ease the throttle back the moment that glassy calm shows up, because a choppy surface just pushes the bird deeper into the roots where you'll never get a clean look at that long, snaky neck.
Once we're idling, we watch for a single thin black line breaking the surface with no splash at all — that's the tell. Unlike a cormorant, which bobs and re-dives in short hops, an anhinga tends to stay under for a long stretch, spearing a fish on that dagger bill before it shows itself again. We'll cut the engine and let the boat drift on the current rather than motor toward it, because powering back up reads to the bird as a threat, and it disappears into the prop roots for good.
When it finally surfaces near a mangrove root or an old channel marker, we hold position and let the guest at the bow point it out first — there's something about a first-timer finding that periscope neck on their own that beats any captain narrating it for them. From there it's a short wait for the real payoff: wings snapped open wide against the sky, held out to dry, since an anhinga's plumage isn't built to shed water the way a duck's is. Perched like that, low light behind it, it reads almost like a black cross nailed to a dead branch.
We ask guests to keep their hands low and their voices lower once we're this close, because a sudden point off the bow or a loud “there it is” spooks the bird faster than the engine ever will. A slow raised hand, or just a quiet nod toward the marker, buys everyone a longer look than calling it out ever does — it's a small habit, but it's the difference between a two-second glimpse and watching the whole drying routine play out.
If the tunnels off the Marco River are running thick with weekend boat traffic, we'll duck into a quieter mangrove cut instead and wait it out there — anhingas don't tolerate much disturbance, so patience beats persistence every time we run this water. On a slower private charter timed away from the midday rush, we can idle in these creeks as long as it takes, which is really the only honest way to get a good look at a bird that spends half its life hidden underwater.
Anhingas share these same quiet mangrove edges with the herons, egrets and nesting colonies we cover in our rookery guide, so a slow morning back in this water rarely turns up just the one bird. We like these tunnels precisely because they reward stillness — ours and the bird's both.
