    Common Gallinule Life History


    Habitat Marshes

    Common Gallinules use freshwater and brackish marshes, ponds, and lakes that have a mix of submerged, floating, and emergent aquatic vegetation and are open water year-round. They also use artificial aquaculture ponds, rice fields, sewage lagoons, and urban stormwater retention ponds.

    Food Plants

    Common Gallinules eat vegetation, seeds, snails, and insects. They pick sedge, grass, pondweed, duckweed, and flower seeds from the water surface or just below the surface. Gallinules flip over leaves with their feet to grab snails and insects hidden below.

    Nest Placement

    Nest Floating

    Common Gallinules nest in marshes, lakes, and ponds with emergent vegetation. They tend to build nests on top of thick mats of aquatic plants near the water's edge, but sometimes nest in trees or shrubs.

    Nest Description

    Males and females construct a wide bowl of grasses and sedges. Males tend to collect most of the nesting material while females arrange and anchor it to emergent vegetation near the water's edge. Common Gallinule nests are around 10–12 inches wide.

    Clutch Size:3-15 eggs
    Number of Broods:1-2 broods
    Egg Length:1.5-2.1 in (3.9-5.3 cm)
    Egg Width:1.1-1.4 in (2.8-3.5 cm)
    Incubation Period:19-22 days
    Egg Description:

    Light gray with darker scattered specks and spots.

    Condition at Hatching:

    Eyes open and covered in blackish down.

    Behavior Dabbler

    The long-toed Common Gallinule walks atop floating vegetation and soft soils in a crouched position while slowly flicking its tail up. Seldom do you see them fly, but when they do, their flight is labored. They stride through water pumping their head forward with tail held horizontally and wings held up over the back. During the breeding season, they are territorial and generally associate only with their family group, but during the winter they forage in groups often with American Coots and ducks. Common Gallinules can form long-lasting pairs, but sometimes males mate with more than one female. Females may occasionally share a mate and a nest with their daughter and cooperatively raise the offspring. Young birds that have not found a mate of their own sometimes help their parents brood and feed nestlings.

    Conservation Low Concern

    Common Gallinules are common, but their populations declined by nearly 1.5% per year between 1966 and 2015, according to the North American Breeding Bird Survey, resulting in a cumulative decline of 52%. The species rates a 10 out of 20 on the Continental Concern Score, which means it is not on the Partners in Flight Watch List and is a species of low conservation concern. The Hawaiian subspecies is endangered in Hawaii due to habitat loss and predation by introduced predators such as rats, mongoose, cats, and dogs. Threats to Common Gallinules in North America are not well known. In some areas loss of wetland habitat may threaten them, but in other areas populations have grown, taking advantage of newly created marshy areas such as retention ponds and rice fields. In North America Common Gallinules are hunted in several states, but the impacts due to hunting are unclear because available hunting data lump Purple and Common Gallinule species together.
