It looks like a duck, swims like a duck, and hangs out with ducks—but make no mistake: the American Coot is doing its own thing.
The American Coot (Fulica americana) is one of North America’s most recognizable waterbirds, yet also one of its most misunderstood. Often dismissed as “that weird black duck,” the coot is neither weird nor a duck—though it is delightfully awkward, surprisingly aggressive, and endlessly fascinating.
Let’s give this red-eyed marsh menace the respect it deserves.
Meet the American Coot
American Coots are members of the rail family (Rallidae), which also includes rails and gallinules. That family connection explains a lot about their behavior—especially the walking, running, and general disregard for the graceful reputation of waterbirds.
- Scientific name: Fulica americana
- Length: 13–17 inches (33–43 cm)
- Wingspan: 23–28 inches
- Lifespan: Up to 9 years
They’re chunky, dark slate-gray birds with a white bill, a bold frontal shield, and piercing red eyes that suggest they’ve seen some things.
Habitat: Wetlands Are Non-Negotiable
If there’s water and plants, a coot might be there.
American Coots rely heavily on freshwater wetlands and are especially fond of places with abundant aquatic vegetation.
You’ll commonly find them in:
- Marshes and swamps
- Ponds and lakes
- Slow-moving rivers
- Reservoirs and urban wetlands
During migration and winter, coots often gather in large flocks on open water, sometimes numbering in the thousands. These groups—often called “rafts”—can look like floating punctuation marks scattered across a lake.
You can explore their range and seasonal movements via the Cornell Lab of Ornithology.
How to See an American Coot in the Wild
Finding an American Coot is rarely difficult. Recognizing it for what it is—that’s the real win.
Best Tips for Spotting Coots:
- Scan open water. Especially near marshy edges.
- Look for dark bodies with white bills.
- Watch them walk. The chicken-like strut is unmistakable.
- Visit in winter. Numbers increase dramatically.
They’re often mixed in with ducks, but their posture, movement, and attitude quickly set them apart.
Identification: How to Know It’s an American Coot
Once you know the field marks, coots are impossible to unsee.
Key Identification Features:
- Dark gray to black body
- Bright white bill with a white frontal shield
- Red eyes
- Lobed toes (not webbed)
Those lobed toes are a big deal. Instead of webbing like ducks, coots have individual toes with wide lobes—perfect for swimming and walking on vegetation.
In flight, coots show a white undertail and require a comically long running start across the water before liftoff.
For ID comparisons, the Audubon Field Guide is a helpful resource.
Behavior: Aggressive, Social, and Slightly Chaotic
American Coots are famously… spicy.
They’re highly territorial during breeding season and will chase, peck, and body-check rivals with impressive enthusiasm. Outside of breeding season, however, they become intensely social, forming large flocks that feed and move together.
On land, coots walk and run confidently. On water, they bob and dive. In the air, they flap furiously and briefly, as if annoyed by the whole situation.
It’s all very on-brand.
Diet: Aquatic Vegetarians (Mostly)
American Coots are primarily herbivorous, which is somewhat unusual among waterbirds.
- Main diet: Aquatic plants and algae
- Also eaten: Insects, snails, small fish, tadpoles
They often dive underwater to graze on submerged vegetation, popping back up like feathery periscopes.
Fun fact: coots are known to steal food from ducks, particularly when plant resources are scarce. Sharing is optional.
Nesting & Family Life: Organized Chaos
American Coots build floating nests anchored to vegetation. Both parents help construct the nest, incubate eggs, and raise young.
Coot chicks are… unforgettable.
They hatch covered in black down with bright orange and red patches on their heads and necks, looking like tiny punk rockers who wandered into a wetland.
Parents may practice “selective feeding,” favoring stronger chicks—a behavior that sounds harsh but is surprisingly common in birds.
Why the American Coot Matters
Coots play a vital role in wetland ecosystems by:
- Controlling aquatic vegetation
- Recycling nutrients
- Serving as prey for raptors and mammals
Because they rely on healthy wetlands, coots are excellent indicators of water quality and habitat health.
According to the State of the Birds report, protecting wetlands is essential for species like the American Coot—and countless others that share these ecosystems.
Final Thoughts from the Marsh Edge
The American Coot may never win a beauty contest or a grace award—but that’s not the point.
This bird is bold, adaptable, and unapologetically itself. It thrives where water and plants meet, holding its own among ducks, geese, and herons with pure confidence and a white bill that refuses to be ignored.
Next time you see one paddling, strutting, or starting a low-key feud in the marsh, take a moment to appreciate the coot. It’s doing important work—just not quietly.
Stay curious, stay kind—and if a bird poops on you today, take it as a sign of good luck.
