Common Gallinule
Common Gallinule
Gallinula galeata
At a Glance
Adaptable and successful, this bird is common in the marshes of North and South America. It was formerly considered to belong to the same species as the Common Moorhen, widespread in the Old World. The gallinule swims buoyantly, bobbing its head; it also walks and runs on open ground near water, and clambers about through reeds and cattails above the water. Related to the American Coot and often found with it, but not so bold, spending more time hiding in the marsh.

Habitat
Fresh marshes, reedy ponds. May be on still or slow-moving waters. Favors fresh marshes with some open water, ideally with some open ground and some dense cover along margins. Sometimes on more open ponds with only small amount of marsh cover. Found with American Coot in many places, but requires more marsh growth.

Behavior
Eggs
8-11, sometimes 5-13. Buff, irregularly spotted with brown. Incubation is by both sexes, 19-22 days.
Young
Can swim well shortly after hatching. Young fed by both parents, sometimes by older siblings from earlier broods; gradually learn to feed themselves, finding most of own food after about 3 weeks, though still fed sometimes by parents past 6 weeks. Young capable of flight at 40-50+ days. 1 or 2 broods per year, rarely 3.
Feeding Behavior
Forages while swimming, walking on land, or climbing through marsh vegetation. While swimming, may dip head underwater, or may up-end with tail up and head down; sometimes dives.
Diet
Omnivorous. Major food items include leaves, stems, and seeds of various water plants, also fruits and berries of terrestrial plants. Also eats insects, spiders, earthworms, snails and other mollusks, tadpoles. Sometimes eats carrion, eggs of other birds.
Nesting
In courtship, male chases female on land; both stop, bow deeply, preen each other's feathers. Other displays involve lowering head and raising tail, exposing white patches under tail. Nest site is in marsh over shallow water, sometimes on ground or in shrub near water. Nest (built by both sexes) is solidly constructed platform (or wide, shallow cup) of cattails, bulrushes, reeds; often has a ramp of similar material leading down to water. Similar platforms built nearby, may be used for resting or brooding.
Conservation
Conservation Status
Undoubtedly has declined over much of range owing to loss of wetlands. Still widespread and may be locally common where good marsh habitat exists within historical range.
