Rails, Gallinules, and Coots
Gallinula galeata
The Common Gallinule is an adaptable marsh bird found across the Americas, often seen swimming with a head-bobbing motion or walking on floating vegetation. This species, formerly considered the same as the Old World Common Moorhen, is distinguished by its striking facial shield and white flank stripe. It is a conspicuous member of the rail family, frequently vocalizing from dense wetland cover.
Typical adult measurements.
Individuals and populations vary.
01 / The telltale details
Start with shape and behavior. Then look for the smaller details.
Slaty-gray body with a browner back, a prominent white stripe along the side, and white outer tail feathers.
Adults have a thick, bright red bill with a yellow tip, extending into a brilliant red shield on the forehead.
Long, greenish-yellow legs with large, unwebbed toes adapted for walking on soft surfaces and vegetation.
Paler gray or olive-brown plumage, duller legs and bill, and lacking the vibrant red frontal shield of adults.
02 / A place in the world
Common Gallinules inhabit freshwater and brackish marshes, reedy ponds, lakes, and canals. They prefer areas with a mix of open water and dense emergent vegetation, such as cattails, often with some open ground along the margins.
This species breeds from southern Canada through much of the eastern and southwestern United States, south through Central America, the Caribbean, and into South America to northern Argentina, Uruguay, and Brazil. It is also found in the Galápagos and Hawaiian Islands.
Northern populations are migratory, moving south for the winter to more temperate climates, including the southern U.S., Mexico, and Central America. Year-round resident populations exist in parts of the southwestern U.S., Mexico, and throughout its southern range.
03 / Listen a little closer
Common Gallinules produce a variety of vocalizations, including clucking, squawking, yelping, and whinnying calls. They may also emit loud hisses when threatened.
04 / The life behind the feathers
Common Gallinules are omnivorous, primarily consuming a variety of plant material including seeds, leaves, stems, and roots of aquatic plants. They also eat small invertebrates such as insects, spiders, earthworms, snails, and occasionally small fish and tadpoles.
They forage by swimming, walking on floating vegetation, or pecking at the ground near water. They may scoop items from the water surface, dive for submerged plants, or flip over leaves with their feet to find hidden prey.
Nests are typically wide, bowl-shaped structures made of grasses and sedges, often built on thick mats of aquatic plants near the water's edge or in emergent vegetation. Both parents construct the nest and tend to the young.
These birds swim buoyantly, often bobbing their heads, and can clamber through dense reeds. During the breeding season, they are territorial, but in winter, they may gather in groups, sometimes alongside American Coots. They often stay hidden in vegetation but can become accustomed to human presence.
One more reason to pay attention
Newly hatched Common Gallinule chicks possess wing spurs that aid them in climbing into the nest or grasping vegetation.
The Common Gallinule was reclassified as a distinct species from the Old World Common Moorhen in 2011, based on genetic and morphological differences.
Some young Common Gallinules from a first brood may assist their parents in raising subsequent broods, a behavior known as cooperative breeding.
05 / An eye for the difference
Coots have a whitish bill and lack the red frontal shield and white flank stripe of the Common Gallinule.
Purple Gallinules are more vibrantly colored with iridescent purple-blue plumage and a pale blue frontal shield.
The Common Moorhen is an Old World species, visually very similar but genetically distinct from the Common Gallinule.
