Its total length is {{convert|27|to(-)|32|cm|in|abbr=on}}. Its brownish upper parts and grey chest contrasts clearly with the buff belly. The back and wings are barred, but this is faint (often barely visible) in the males. Additionally, the amount of barring to the upperparts varies among the subspecies. It is the only tinamou in its range with rosy-red legs. BehaviorAs 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. EtymologyCrypturellus is formed from three Latin or Greek words/parts. kruptos meaning covered or hidden, oura meaning tail, and -ellus a Latin diminutive suffix. Therefore Crypturellus means small hidden tail.[5]TaxonomyAll 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.[6] Red-legged tinamou subspecies are:
The taxonomy, beyond this, 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.[7] 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.{{Citation needed|date=February 2009}} Range and habitatThe red-legged tinamou lives in Guyana, Suriname, Colombia, Venezuela and northeastern Brazil, and on Margarita Island.[8] It may also be found in French Guiana.[1] It is favored habitat is dry forest, although it can be found in moist forest and lower elevation shrubland and grasslands. It prefers elevations below {{convert|1300|m|ft|abbr=on}}.[24] ConservationThe red-legged tinamou is uncommon to locally common in most of its range, but the Magdalena tinamou is very rare (perhaps extinct), while the Colombian tinamou is endangered. In both cases the main problem is habitat destruction, but hunting is another issue. The IUCN lists this bird as Least Concern,[1] with an occurrence range of {{convert|1800000|km2|sqmi|abbr=on}}.[9] Footnotes1. ^1 2 {{IUCN|id=22729569 |title=Crypturellus erythropus |assessor=BirdLife International |assessor-link=BirdLife International |version=2013.2 |year=2012 |accessdate=26 November 2013}} 2. ^1 2 3 4 5 6 7 Brands, S.
