N. m. maculosa
The Spotted Nothura is approximately 24–25.5 cm (9.4–10.0 in) in length. The upper parts are brown with streaked buff. The under parts are buff streaked with black and brown on the breast, with barring to the flanks. Its crown is black streaked with buff and the throat is white. The overall hue in colour varies greatly over its range; in part caused by the differences in soil at the specific localities. It and the closely related Chaco Nothura, N. chacoensis, are the only nothuras with barring to both webs of the primaries. The legs are dull yellowish-grey or brown.
The call of the Spotted Nothura is a series of brief high-pitched notes.
This species can reproduce rapidly, as the female is mature within 2 months and can have five to six broods per year. The male does not mature as fast. The male will incubate the eggs and raise the chicks. Like most tinamous, its eggs have a spectacular glossy porcelain-like shell. This is colored a rich maroon or chocolate brown in this species. The clutch contains 4-6 eggs.
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.
