Despite its name, this mid-sized tinamou is not endemic to Brazil, as its range also extends to eastern Peru and northwest Bolivia, as well as across much of Amazonian Brazil south of the Amazon River east as far as the state of Maranhão. There is also an isolated population in northeast Brazil, in the states of Pernambuco and Alagoas. Like most forest-dwelling tinamous, it is a devilishly difficult bird to see, although males respond to playback or imitations of their insect-like, slightly wavering song, which may be heard even during the hottest hours of the day. Typically sedentary, the Brazilian Tinamou feeds on seeds, berries, snails and arthropods, all characteristically foraged among the dense leaf litter of its forest home. Like most Crypturellus tinamous, the nest is a mere depression in the ground, often covered by leaves. Four eggs apparently constitute a regular-sized clutch.
