- Common Moorhen, Florida Gallinule
- Gallinule poule-d'eau, Poule d'eau (French)
- Pollo de agua, Gallareta frentirroja, Pollona negra (Spanish)
- The Common Gallinule has long toes that makes it possible to walk on soft mud and floating vegetation. The toes have no lobes or webbing to help in swimming, but the moorhen is a good swimmer anyway.
- The Common Gallinule sometimes lifts its feet out of the water in front of the body while swimming, perhaps to pass over vegetation.
- Newly hatched chicks of the Common Gallinule have spurs on their wings that help them climb into the nest or grab emergent vegetation.
- One subspecies of the Common Gallinule is found only in the Hawaiian Islands and has been known as the Hawaiian Moorhen, or 'alae 'ula.
- The oldest recorded Common Gallinule was at least 9 years, 10 months old when it was recaptured in Louisiana in 1940, during some of the very earliest banding studies in the U.S.
Freshwater or brackish marshes with tall emergent vegetation, ponds, canals, and rice fields.
Seeds of grasses and sedges, and some snails.
- Clutch Size
- 3–15 eggs
- Egg Description
- Gray or buff with variable speckles and splotches.
- Condition at Hatching
- Eyes open; covered with gray down except on head and wings.
A wide bowl of grasses and sedges, usually taken from near the nest site. Most commonly anchored to emergent vegetation within a meter of water.
Picks food from water surface or from emergent plants while walking or swimming. Dips head, dabbles, and occasionally dives. Flips floating leaves to take snails clinging to undersides.
Common Gallinule populations decreased between 1966 and 2014, according to the North American Breeding Bird Survey. These birds are listed as threatened or as a species of special concern in several Midwestern and Northeastern states because of loss of wetland habitat, predation by introduced mammals, and other factors. The Hawaiian Common Gallinule population is on the on the 2014 State of the Birds Watch List, which lists bird species that are at risk of becoming threatened or endangered without conservation action.
