The generally common White-winged Coot is widely distributed across the southern third of South America, from Chile and Argentina in the south, north to southernmost Brazil, Paraguay, and Bolivia. It is found on a wide variety of inland wetlands, provided there is grassy or vegetation-free shores. Like other coots, this species is principally blackish with white undertail coverts, but has a small orange-red frontal shield, and a yellow to greenish-yellow bill, sometimes marked with a dark tip. In the north of the species’ range it appears to breed mainly in the austral spring and summer, but further south the season appears to be more prolonged and seems to commence in the late autumn. The nest is a floating platform of vegetation, similar to that constructed by most coot species.
