The Solitary Tinamou, Tinamus solitarius, is a species
of paleognath ground bird
. This species is native to Atlantic forest of eastern Brazil
.
s. 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. Formerly, this bird was divided into two subspecies
: T. s. pernambucensis in north-east Brazil (Pernambuco and Alagoas
), and T. s. solitarius found in south-east Paraguay and extreme north-east Argentina. The former, however, turned out to be not distinct from the nominate but rather individual birds that showed a particular color morph which is now known to also occur elsewhere. Notably, the hue of the back varies between olive and rusty, and the intensity of the lower neck's plumage color also varies. The black barring in these areas is more or less strong. pernambucensis refers to yellower birds with much barring, especially on the neck.

species, it may soon become vulnerable with a range occurrence of 990000 km² (382,241.1 sq mi). The population formerly believed to be referred to by pernambucensis is either very rare or already extirpated. These northern birds have always been fairly rare in historical times, with possibly not more than 6 specimens in museums.
It has been noted that this species is not hard to introduce to suitable habitat. Solitary tinamous were found to persist in numbers in a forest fragment of 1500 acres (607 ha) where they were not originally found. It is not considered globally threatened by the IUCN.

Behavior
Like other tinamous, it lays oddly-shaped eggs with a glossy, colorful shell, and it eats fruits, and seeds off the ground or low plants. Males will incubate the eggs which are in a nest on the ground, and will also rear the young for the short period of time before they are independent.Ecology
