Spot-flanked Gallinule
Porphyriops melanops
Paddling briefly into open water before slipping back into dense marsh vegetation, a spot-flanked gallinule reveals the line of white spots along its flanks that gives this quiet South American marsh bird its name.
Overview
The spot-flanked gallinule, Porphyriops melanops, is a Least Concern marsh bird found across freshwater wetlands throughout much of South America. A close relative of coots and moorhens, it shares their swimming lifestyle while remaining a secretive and relatively unobtrusive presence within dense marsh vegetation.
A quiet life in the reeds
Unlike some of its louder marsh-dwelling relatives, the spot-flanked gallinule keeps a low profile, spending most of its time concealed within reeds and other dense vegetation and venturing into open water only briefly before retreating back to cover.
Status
Least Concern, remaining widespread across suitable freshwater marsh habitat throughout its South American range.
