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.
The brushland tinamou has two subspecies as follows:
- N. c. cinerascens, the nominate race, occurs in southeastern Bolivia, northwestern Paraguay, and central Argentina.
- N. c. parvimaculata occurs in northwestern Argentina in eastern La Rioja Province
The brushland tinamou is approximately 31.5 cm (12.4 in) in length and weighs 540 g (1.19 lb). Its upper parts are grey to olive-brown barred with black and prominently streaked with white. Its crown is black, the sides of its head and its throat are white, its lower throat is barred black, its breast is grey spotted with white, and its belly is whitish. Its legs are dark grey. The female is larger and darker.
The brushland tinamou prefers to live in dry shrubland up to 1,000 m (3,300 ft) in altitude. But it can regularly be found as high as 2,000 m (6,600 ft), and also in dry savanna, dry grassland, or grassland that is seasonally flooded, and also pastureland and farmland.
The call of the brushland tinamou is a series of seven to ten clear whistled notes that carry, and will be hard as they defend their range of about 50 acres (20 ha). They feed off of insects and small animals and some fruit.
Males attract two to four females and supervise their laying of eggs in the nest, which is typically hidden in brush. Females will leave to find other males and the male will incubate the eggs and raise the chicks.
