The Red-legged Tinamou, Crypturellus erythropus, is a dumpy, ground-dwelling bird found in the tropics and lower subtropics of northern South America in the Guyanas (French Guiana, Guyana and Suriname), Colombia, Venezuela and north-east Brazil, the north-east Amazon Basin. It is commonly found in dry forest and dry shrubland at altitude up to 1,300 m. However, it may also be found at humid forest habitats.
As other tinamous, it is recorded infrequently, except by its whistling voice. It has been recorded feeding on seeds, berries, snails and insects. Little is known about its breeding behavior, but the glossy eggs are pale greyish lavender with a variable amount of pink suffusion.
The taxonomy remains unclear, with some authorities considering the taxa saltuarius, idoneus, and columbianus as monotypic species rather than subspecies of the Red-legged Tinamou. The SACC rejected a proposal to elevate these to species status, arguing that the presently available data fail to support the split.
Additionally, several subspecies usually associated with the Red-legged Tinamou have been associated with other species in the past, especially the Thicket Tinamou, the Choco Tinamou and the Yellow-legged Tinamou.
