Its upperparts are dark brown, with grey to brownish under parts and head. Its bill and legs are red. TaxonomyThe small-billed tinamou is a monotypic species.[3] 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.[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]BehaviorLike other tinamous, the small-billed 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] DomesticationThe small billed tinamou has been considered an ideal candidate for domestication as the birds can raise 3-4 broods per year and are resistant to diseases that affect chickens Range and habitatThe small-billed tinamou prefers dry savanna, but will also reside in lowland shrubland.[6] Its range is Amazonian South America; Brazil except for the southeastern portion, northeastern Peru, eastern Bolivia, Paraguay, and northeastern Argentina.[3][6] ConservationThe IUCN classifies this tinamou as Least Concern,[1] with an occurrence range of {{convert|6700000|km2|sqmi|abbr=on}}.[6] Footnotes1. ^1 {{IUCN|id=22678232 |title=Crypturellus parvirostris |assessor=BirdLife International |assessor-link=BirdLife International |version=2013.2 |year=2012 |accessdate=26 November 2013}} 2. ^Brands, S.
