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.[4] EtymologyCrypturellus is formed from three Latin or Greek words. kruptos meaning covered or hidden, oura meaning tail, and ellus meaning diminutive. Therefore, Crypturellus means small hidden tail.[5]DescriptionThe grey-legged tinamou is approximately {{convert|30|cm|in|abbr=on}} in length. It is dark brown above with finely barred black on its lower back, it is rufous below, has tinged grey on its upper breast, the sides of its belly are banded buff, its head and neck are rufous, its throat white, and its legs are greyish. The female is darker on her lower back with narrow light buff barring.{{Citation needed|date=February 2009}} BehaviorLike other tinamous, the grey-legged tinamou eats fruit off the ground or low-lying bushes. They also eat small amounts of invertebrates, flower buds, tender leaves, seeds, and roots. The male incubates the eggs which may come from as many as 4 different females, and then will raise them until they are ready to be on their own, usually 2–3 weeks. The nest is located on the ground in dense brush or between raised root buttresses.[4] Range and habitatIt is found in dry shrubland up to {{convert|500|m|ft|abbr=on}} altitude. It may also be found in moist or drier lowland forest. This species is native to east central Colombia, southern Venezuela, and northwestern Brazil.[3] It may also be found in far eastern Peru.[6] ConservationIn 2012 the IUCN classifies this Tinamou as Near Threatened,[1] with an occurrence range of {{convert|59000|km2|sqmi|abbr=on}}.[6][7] Footnotes1. ^1 {{IUCN|id=22678213 |title=Crypturellus duidae |assessor=BirdLife International |assessor-link=BirdLife International |version=2013.2 |year=2012 |accessdate=26 November 2013}} 2. ^Brands, S.
