Purple Gallinule

How to find it

Look in dense freshwater wetlands with floating plants such as water lilies and water hyacinth. It is fairly easy to see when walking on floating plants, and harder to see in tall rice stalks. The usual way to bird the northern wetlands is by boat, with guides drifting quietly through the channels to the lily-pad lagoons. A tour boatman at the Medio Queso marsh knew where to find it, and the group saw several birds. Flooded rice paddies are another place to look. One Costa Rica birder finds it generally less common than northern jacanas and black-necked stilts sharing its wetlands, so scan carefully.

How to recognise it

Adults have a deep violet-blue head, neck and breast, a bronzy-green back, a red bill with a yellow tip, and yellow legs. The undertail is white. Above the red and yellow bill sits a pale blue shield on the forehead, the single best mark to look for.

Immatures look quite different: brownish bronze with a pale bill and shield. A juvenile has been photographed in Costa Rica, so it is worth knowing the young birds too.

Light changes how it looks. In good sun the dark plumage shows purple, green and turquoise. In dim light the adult can look dusky or brownish. One Costa Rica writer notes it looks purple or blue only when the sun hits it just right, and otherwise reads as a shiny blackish bird.

Behaviour and diet

Very long toes let it walk across floating plants such as lily pads. In flight the legs dangle, and it usually flies only short distances.

In Costa Rica and Panama, Purple Gallinules often raise several broods a year. Young from earlier broods help feed and defend the new chicks. When people threaten the chicks, they can dive fully underwater with eyes shut and stay there until the danger passes.

Where it lives

In Costa Rica it occurs from sea level up to about 1500 m or higher, and one Tico Times writer says it can be found in suitable habitat anywhere in the country. It prefers swampy areas, ponds and flooded pastures with still or slow water, tall grass at the edges and plenty of floating plants. In the tropics it may also use smaller ponds and ditches. It also lives and nests in rice fields.

When to see it

For the northern wetlands, one tour company gives January to March as the best time, when low water concentrates the birds and boat access is at its best. After heavy rains in January and February 2025 the water was still high and birds were scattered, yet the gallinule was still seen on the boat trip. In Guanacaste it breeds in the rainy season, with nesting from mid-May to November and a peak in August.

Similar birds

The Common Gallinule is the look-alike that shares the same wetlands, and a tour report on canoe trips at Aviarios found both species there. The pale blue forehead shield separates the Purple Gallinule from similar species such as the Common Gallinule. In dim light the adult can look dusky or brownish, so wait for better light or a clear view of the shield.

Names and lore in Costa Rica

Costa Rican sources list several Spanish names: gallareta morada, calamón morado, gallina de agua (literally 'water chicken') and polla de agua. Gallareta morada is the name used in Costa Rica and Panama, while other countries use different names, such as gallineta morada in Mexico and polla azul in Colombia.

Status and conservation

The AOCR list marks it as a resident (R), a Costa Rican natural history note calls it common in some places where habitat suits it, and the IUCN lists it as Least Concern.

Photography tips

Wait for good sun, when the dark plumage shows purple, green and turquoise. In dim light it can look dark or brownish. Birds walking on floating plants are fairly easy to see, while tall rice stalks hide them. A quiet drift by boat lets you approach without flushing it, and it usually flies only short distances.
