EURASIAN COOT

Water’s Edge Acrobat: The Eurasian Coot 

If you have ever visited a local Australian park, lake, or wetland, you have almost certainly seen a Eurasian Coot (Fulica atra). Often referred to simply as the Australian Coot, these charcoal-coloured waterbirds are an incredibly common sight, bobbing like little dark corks on the water’s surface.

Because they swim alongside Pacific Black Ducks and swans, most people naturally assume they are a type of duck. However, they are actually members of the rail and crake family (Rallidae)!

Sharon: I found a nice mob of Eurasian Coots on a large outback Queensland dam where they seemed quite at home foraging amongst the reeds. I don’t often get to see them out of the water, so I was lucky, in this ‘Close Encounter’, to see them foraging around the edges of the dam as well.

What Does It Look Like?

To identify a Eurasian Coot, you just need to look for a striking contrast between absolute darkness and brilliant white.

  • The Adult: They are a plump, medium-sized waterbird completely covered in sooty, slate-grey to black plumage. Against this dark canvas, they feature a stark, bright white bill that extends up onto their forehead to form a fleshy white plate known as a “frontal shield”. If you look closely, you will also notice they have piercing, deep-red eyes.
  • The Bizarre Feet: If a coot steps out of the water onto the grassy bank, look at its feet. Unlike ducks, which have fully webbed feet, the coot has massive, pale grey toes fitted with unique, fleshy flaps known as “lobes”. These lobes fan out when they paddle backward to push through the water, and fold back when they step forward, allowing them to swim efficiently and walk on slippery mud without getting stuck.
  • The “Ugly-Cute” Chicks: Baby coots are an absolute riot to look at. They hatch looking a bit like tiny, angry punks! While their bodies are covered in black fuzz, their heads are wildly vibrant, sporting a halo of bright, fiery red and orange wiry fluff and a surprisingly bald crown.

The Wetland Cycle: Breeding and Longevity

The Eurasian Coot is a highly social bird, but when the breeding season arrives, they become incredibly fierce and dedicated parents.

  • Floating Nurseries: Working together, the male and female construct a massive, messy platform nest out of woven reeds, twigs, and water ribbons. These nests are usually built right into the shallow reeds or anchored to submerged branches, keeping them safely surrounded by water.
  • Shared Parenting: The female typically lays a clutch of between 5 and 7 lightly speckled eggs. Both parents share the incubation duties, which last for around three weeks. Once the chicks hatch, the parents will aggressively defend their territory, chasing away much larger swans and ducks that drift too close.
  • Longevity: If they can survive their highly vulnerable chick stage, they are surprisingly resilient. In the wild, Eurasian Coots typically live for around 9 to 10 years, with some banded birds recorded reaching up to 15 years of age!

Fascinating Facts: Water Runners and Strict Parenting

Walking on Water: Coots are heavy birds with relatively short wings. When they are startled or need to take flight quickly, they can’t simply launch into the air. Instead, they perform a spectacular, noisy “run” across the surface of the water, furiously flapping their wings and slapping their lobed feet against the surface until they build up enough speed to lift off!

Feeding: When they forage for aquatic weeds, algae, and small water snails, they don’t just tip upside down like many ducks. A coot will perform a distinct, energetic little “jump” out of the water before diving head-first beneath the surface.

Watching a flock of coots feed is a study in diverse hunting styles. They have developed a few highly effective—and sometimes hilarious—ways to fill their bellies:

The Deep Dive: While ducks often just tip their tails in the air to reach the bottom (dabbling), the coot puts its whole body into it. With a distinct, energetic little upward leap, they plunge entirely underwater. They can stay submerged for up to 10 seconds, using their powerful lobed feet to propel themselves to the muddy bottom to rip up fresh aquatic weeds.

The Lawn Mowers: Because their unique feet make walking on land surprisingly easy, coots don’t just stay in the water. You will frequently see large flocks wandering out onto the grassy banks of the lake, grazing methodically on the short grass and clover just like a flock of tiny, dark sheep.

Strict Survivalists: Life on an Australian wetland during a drought is incredibly harsh. If a pair of coots has too many chicks and food becomes critically scarce, they will aggressively peck at their own begging young, prioritising food for only the strongest chicks to ensure at least some of the brood survives the season.

Conservation Status and Environmental Threats

Globally and nationally, the Eurasian Coot is classified as a species of Least Concern. Their sheer adaptability means they have successfully colonised urban stormwater drains, ornamental park lakes, and agricultural dams across the country.

However, this reliance on suburban and agricultural waterways comes with significant localised threats. Poor water quality due to industrial chemical run-off, heavy agricultural fertilizers, and blue-green algae blooms severely impacts their health and destroys the aquatic plants they rely on for food. Furthermore, as they forage in heavily populated areas, they frequently become fatally entangled in discarded recreational fishing lines and plastic rubbish.

What Can We Do to Help the Species?

Protecting the Eurasian Coot is all about ensuring our shared waterways remain clean, healthy, and thriving. Here is how you can help:

  • Dispose of Fishing Line: The absolute best thing you can do for all waterbirds is to cut up and safely bin any discarded fishing line or tackle you find by the water’s edge.
  • Don’t Feed Them Bread: While it is tempting to feed the coots at the local park, human bread offers zero nutrition, pollutes the water, and causes severe bone deformities in growing chicks. If you must feed them, offer thawed frozen peas or shredded leafy greens instead!
  • Support Wetland Planting: Advocate for your local council to keep the edges of urban lakes and stormwater drains heavily planted with native reeds and sedges. This provides the crucial nesting materials and hiding spots the coots need to safely raise their fiery-headed chicks.
