Common Moorhen
Gallinula chloropus
The Common Moorhen is a widespread waterbird of the rail family, often found in well-vegetated freshwater habitats. Known for its distinctive red frontal shield and bill, this species navigates aquatic environments with ease, swimming like a duck and walking across floating vegetation with its long toes. It is a familiar sight across much of the Old World.

01 / The telltale details
You’ll know it
when you see it.
Start with shape and behavior. Then look for the smaller details.
- 01
Adult Plumage
Predominantly dark gray to black body with brownish upperparts, white streaks on flanks, and a prominent white undertail.
- 02
Bill and Frontal Shield
Bright red bill with a yellow tip, extending into a rounded, red frontal shield on the forehead.
- 03
Legs and Feet
Yellow-green legs with long, unwebbed toes, enabling it to walk on floating vegetation.
- 04
Juvenile Appearance
Young birds are browner overall and lack the distinctive red frontal shield of adults.
02 / A place in the world
Where life
takes it.
Common Moorhens inhabit a variety of freshwater wetlands, including marshes, ponds, canals, and rivers. They prefer areas with emergent vegetation for cover and open water for foraging.
Stay a while. Or follow the season.
Common Moorhens can be both resident and migratory, depending on the region. Populations in areas where waters freeze, such as eastern Europe, will migrate to more temperate climates for the winter.
03 / Listen a little closer
A voice
of its own.
Emits a variety of loud, harsh calls, including clucking sounds, chicken-like grunts, and an explosive croak during the nesting season.
04 / The life behind the feathers
A day in its world.
On the menu.
An opportunistic omnivore, its diet includes aquatic vegetation, seeds, grasses, and fruits. It also consumes small aquatic creatures such as insects, snails, worms, small fish, and crustaceans.
Moorhens forage both in and out of the water. They swim, dipping their heads to sift the surface or dive for submerged items. On land, they graze on vegetation or glean insects.
A place to begin.
The nest is a bulky, well-rimmed cup constructed from dead vegetation and lined with grass, typically situated over water and anchored to emergent plants or shrubs. Both parents share incubation duties.
The little routines.
Often secretive, Common Moorhens can become accustomed to human presence in some areas. They are territorial during breeding season, defending their nesting space. They roost in low trees or bushes at dusk.
One more reason to pay attention
A familiar face.
A few surprises.
The name 'moorhen' derives from an old sense of 'moor' meaning marsh, accurately reflecting its preferred habitat.
Common Moorhen chicks are precocial, meaning they are relatively mature and mobile shortly after hatching.
Some subspecies, such as the Mariana Common Moorhen, are endangered due to habitat loss and other threats.
05 / An eye for the difference
Could it be
someone else?
Common Gallinule
Gallinula galeataThe Common Gallinule, found in the Americas, was formerly considered the same species but is now recognized as distinct; it has a frontal shield that is less wide towards the bill with a straighter top.
Eurasian Coot
Fulica atraEurasian Coots are entirely black with a white frontal shield and bill, lacking the red and yellow coloration of the moorhen.
Water Rail
Rallus aquaticusWater Rails are much more secretive, typically smaller, and have a longer, thinner bill without a frontal shield.
