What’s that small black duck with a white bill?

2010 November 14

VICKSBURG, MISS. — As autumn deepens across North America, waterfowl numbers are swelling in lakes, rivers, ponds, and even puddles. You might be seeing some new birds on the water near you. And every year, there’s one bird that seems to get people especially curious. It’s smaller than a Mallard, its head and body are black, and its bill is white. It’s usually found in swimming in groups, often in parks and other areas near people. But what is it called?

The black “duck” with a white beak is an American Coot

Here’s a picture of a coot (Fulica americana):

American Coot, Fulica americana

If you look closely, you can see the American Coot’s bright red eye and dark reddish forehead knob, the dark ring near the end of its bill, and white under its tail. (Note: If you live in Europe or another part of the world, odds are you have a similar-looking but slightly different coot species in your area. There are several species around the world, including the very widespread Eurasian Coot in Europe, north Africa, Asia, and Australia.)

At this point, you may be thinking that this sort of looks like the birds you saw, but you aren’t quite sure. Maybe you’re thinking something like this: But the birds I saw were darker black or slate gray. Or, I didn’t see the red eye, forehead knob, or ring on the bill. Or, The birds I saw were bigger/smaller than that. Don’t worry. No other North American bird shares the coot’s dark body plumage and bright white bill. Light and distance can affect how you perceive a bird, and which details you see or remember. If you got the white bill and the blackish head and body, you got a coot. Now, here’s step two.

Coots aren’t ducks

Yes, they float and swim like ducks. But lots of different birds do that. Aside from their swimming habits, coots are actually quite different from ducks. Start by studying the coot’s bill shape:

American Coot head and bill

See how pointed the coot’s bill is? And it’s a little bit laterally compressed. That means it’s slightly flattened on the sides, as if you took it between your palms with your thumbs facing up and gave it a little squeeze. You can even see the bird’s nostrils — slits about halfway down the the sides of its bill. All this is very different from a blunt, flat, shovel-shaped duck bill with nostrils on top.

And there’s more. We often see coots swimming in the water, but if you see one on land, be sure to check out its feet. Here’s a beautiful shot by markjdos.

lobed feet of American Coot

Look at those long, lobed toes! Totally different from ducks’ fully webbed (and much shorter) feet. Coots’ toes are suitable for swimming but also for walking around in dense, wet reeds and vegetation.

So if coots aren’t ducks, what are they?

Coot family tree

Coots belong to a family that includes rails, gallinules, and moorhens. Here’s a very colorful coot relative, the Purple Gallinule (Porphyrio martinica). Notice the similarities in its head and bill structure. It has long toes like a coot, but they aren’t lobed. Purple Gallinules spend less time swimming and more time creeping through dense vegetation.

Purple Gallinule, Porphyrio martinica

And here’s another family member, the Clapper Rail (Rallus longirostris), which lives in saltmarshes, where it often remains hidden in thick grasses.

Clapper Rail, Rallus longirostris

Coots, gallinules, and rails are in an order called Gruiformes, along with the big, stately cranes and a handful of other birds like the Limpkin (familiar to many Florida residents), and a few odd birds of the South American rain forests. The order name Gruiformes comes from the Latin word grus, which means “crane.” These words are similar in many European languages; they all came from an ancient Indo-European root word.

So now when you see coots mixed in with domestic ducks at the park…

…or grazing on grass and other plants on the lawn…

…you will know their name and a little bit more about them. Enjoy the coots!

    I thought I was seeing things when I noticed this creature swimming around a retention pond here in the city. I only saw a single bird which seems odd , especially since the article mentions that they travel in groups. It was a nice change from the mallards, Canadian geese and the gulls that frequent Indianpolis, IN.

    I just saw a group of coots for the first time myself today. I thought it was a group of black ducks. They were fishing in the water so I did not get to see those amazing feet. They are all the way up here in northern illinois. Quite amazing!

    Вчера в Горелово (Санкт-Петербург) в небольшом пруду наблюдали ПАРУ лысух в обществе обыкновенных уток. Кормили уток внучки, но лысухи робели, возможно, боялись собаки. Размер ЭТИХ необычных для наших мест птиц такаой же, как и у “наших уток”, правда, БЕЛОГО цвета оперенья”сзади” не заметил.

    Kayaking on a lake in Montana today I saw my first large group of American Coots. I got quite close to them as they fed on the plant life in the shallow cove. Unfortunately, I didn’t see their feet. Wish I had, they are spectacular!

    thanks for this great article! I stumbled upon a huge flock of these birds for the first time today in a public park I always go to, and took many pictures, came home and easily identified the American Coot when I read this.

    Does anyone know why Coots would bamd together in large, dense groups? More than 50 birds floating so close together that they’re actually touching. Two nights in a row we’ve witnessed this behavior – and no one has ever seen them do it before. It’s been very warm here (highs in the 80′s ), but other than that nothing unusual…

    A few will break off from the group if food is offered, but the majority stays in formation.

    We have a place on Cedar Creek Lake in Texas. This week we have hundreds of American Coots flying in. The swarm in formation. Then land in the shallow cove to feed. They take off together making waves and rustling sounds on the water as they take off and move on.

    We live in North Texas and have a beautiful lake outside our independent senior living apartment. About 3 weeks ago must have been 80 or so land on this lake in the middle of town and they seem quite delighted to stay – I hope they do. They are noisy and seemingly cranky little rascals and as I read very territorial. It is in high 70′s here in early December. I hope they stay and breed as we have had such mild winters last couple of years. We have beautiful swans in our lake (3 pairs) and they all have babies. But after 4-7 weeks they all disappear. I guess from the turtles pulling them under.

    When I first saw these cute, sweet little birds, I couldn’t figure out if they were a duck or a type of chicken from far away! But as they got closer to me I was sure that they were from the duck family. So after getting onto your wonderful site and seeing the beautiful pictures you posted, I realized that they are called a Coot! I told my husband to feed them some bread yesterday and to our wonderful surprise they returned this morning for more, about 50 of them! I actually heard their little peeps and knew when they arrived. We used to have ducks and also raised their babies so it was a pleasent surprise seeing them at our RV park in Lake Elsinore, Ca. Cute Coots! Not chickens or ducks! Thanks, Terese’

    We live in West Bloomfield, MI on a canal that leads into Pine Lake. A pair of unusual looking ducks were swimming by our shoreline and we discovered that they are American Coots. This is the first time in 37 years we have seen American Coots. So how do we get them to get them to show us their feet?!

    I was walking in my local Los Angeles County, California park yesterday, and out in the pond I saw one, lone “black duck with a white bill”. I took a picture of it. Today when I was trying to figure out what it was, I stumbled upon this website. Thanks for letting me know it was an American Coot. I could definitely see the “bright red eye and dark reddish forehead knob” on it, and noticed its oddly-shaped, white bill.

    Have an American Coot swimming in our backyard pool today and has been there for over a hour now. Our pool motor has been broke so the pool is a little green (won’t last as the pool guy came by this morning and fixed it) so I guess this Coot thinks it is a pond right now.

    I live in clearlake California we have a home on the east shore of the lake and three times a day I go down to our beach and feed the waterfowl I buy special food for them at walmart,as I was researching wild ducks and bread is bad for there health…I love the variety of birds that come and the little black coots are always the bravest ones…they come right to me now it took a couple of weeks to earn there trust. Also I have mallards and canadian geese ,blue harrons and one bald eagle…its always fun to watch them together,although they all split when the eagle comes..
