The Dot-winged Crake of southern South America is tiny, with brown upperparts striped blackish, and whitish barring on the wing coverts, which is only visible in flight. The underparts are dark gray, becoming even darker over the belly, which is barred white. The bill is dark greenish bill, and the legs are gray washed green. This crake is most abundant and widespread in Buenos Aires province in Argentina, but there are also records elsewhere in the same country, as well as from Uruguay and southernmost Brazil. It usually inhabits temporary and tidal marshes, swamps, wet marshy meadows, and wet to dry grassland, and there is some evidence for a recent decline in the species’ numbers.
