American Coot

Fulica americana

The American coot (Fulica americana), also known as the mud hen or pouldeau, is a medium-sized waterbird that is a member of the Rallidae family. It is often mistaken for a duck but is only distantly related. The coot has a distinctive white bill and frontal shield, with a body length ranging from 34 to 43 cm and a wingspan of 58 to 71 cm. Both sexes appear similar, though males are slightly larger.

Identification Tips

Adult American coots possess a stout white bill and a white frontal shield, often with a reddish-brown spot near the top. Juveniles are marked by olive-brown crowns and a grey body, maturing to adult coloration at around four months. The coot's lobed toes are a unique feature, aiding in terrestrial locomotion.

Habitat

American coots are commonly found in freshwater environments such as reed-ringed lakes, ponds, marshes, and sluggish rivers. They can adapt to saltwater habitats during winter months.

Distribution

This migratory bird is widespread across North America, inhabiting the Pacific and southwestern United States and Mexico year-round, with northeastern regions hosting them during the summer breeding season. In winter, they can reach as far south as Panama.

Behaviour

Coots are highly sociable, especially in winter when they form large flocks. They exhibit various on-water formations and are known for their aggressive defense of territory and offspring.

Song & Calls

The coot's vocal repertoire includes a range of calls with males and females producing distinct sounds. Alarm calls differ between sexes, with males emitting a "puhlk" and females a "poonk."

Breeding

Breeding occurs in May and June, with coots building floating nests in concealed locations. They are monogamous, with both sexes sharing in nest construction and incubation. Clutch sizes average 8-12 eggs.

Similar Species

The American coot can be confused with other coot species, but its white bill and frontal shield, as well as its distinctive calls and aggressive displays, help differentiate it.

Diet and Feeding

Omnivorous by nature, coots primarily consume algae and aquatic plants, supplementing their diet with arthropods, fish, and other aquatic animals during the breeding season.

Conservation status

The IUCN lists the American coot as "Least Concern." They are common and widespread, and their meat is not highly sought after by hunters, which may contribute to their stable population numbers.

A Friendly Place
I love using the bird app, I have a pretty good knowledge of birds. But I do have some gaps in it, so it’s nice to have a safe space to check on a sighting to confirm the species. It’s really enjoyable and I love the badges you can collect. It’s like a real life Pokémon go.

Birding and wellbeing app
Birda is an excellent platform to share your love of Birding and is a great tool of encouragement for a Birding Beginner like me. Birda has a very kind and supportive community of Birding enthusiasts. For me BIRDA is not only a BIRDING but also a WELLBEING App.

Great app for learning Birds
I’ve been using the app for a couple of months and love it....Someone said it’s like a real life Pokémon Go for birds. They’re not far off! It’s something that the family can do that gets you out and about. Well worth downloading no matter your age.

Learning Birding with Birda
I’m relatively new to birding as a hobby, and Birda is a great way to keep track off all the species I see. I’m still working on my ID skills, but the app is great for figuring out potential species, and the online community is so friendly and helpful. Definitely recommend Birda to both early and serious birders! 🐦
