Brushland Tinamou ranges from southern Bolivia through southwestern Paraguay to northcentral Argentina, within which area it generally inhabits dry savanna woodlands, desert scrub, grassy steppes, borders, and even flooded savannas. It is found up to about 2000 m, but usually occurs at lower elevations. The comparatively large range of this species and, more importantly, its habitat requirements (more open areas) have made Brushland Tinamou one of the better studied members of its family. The sexes are basically alike in having grayish to olive brown upperparts barred darker, a blackish crest, and whitish to grayish underparts, with barred flanks. Whereas males are usually solitary birds, females usually move around as 'pairs' or occasionally even in small groups, which may range through the territories of several males. Brushland Tinamous feed on a variety of invertebrate prey, as well as on fruits and seeds.
