The red-winged tinamou (Rhynchotus rufescens) is a medium-sized ground-living bird from central and eastern South America. Other common names for the species include perdiz grande, rufous tinamou, and ynambu.
All tinamou are from the family Tinamidae, and in the larger scheme are also ratites. Unlike other ratites, tinamous can fly, although in general, they are not strong fliers. All ratites evolved from prehistoric flying birds, and tinamous are the closest living relative of these birds.
Coenraad Jacob Temminck first identified the red-winged tinamou from a specimen from São Paulo state, Brazil, in 1815.
