[3] Other common names for the species include perdiz grande, rufous tinamou, and ynambu.

[4] Coenraad Jacob Temminck first identified the red-winged tinamou from a specimen from São Paulo state, Brazil, in 1815.

The red-winged tinamou is approximately 40 to 41 cm (15.7–16.1 in) in length, and weighs 830 g (29 oz), and the female may be slightly larger.

Its range is southeastern, northeastern and central Brazil, eastern Paraguay, southeastern Peru, Bolivia and eastern Argentina[3] At lower elevations (1,000 m (3,300 ft)), it favours marshy grasslands (seasonally flooded) and forest edges.

It can be an agricultural pest, feeding on cereals, rice and peanuts, as well as being predatory, taking poisonous snakes and even jumping up into the air to snatch an insect off a leaf.
