The Choco tinamou or Chocó tinamou (''Crypturellus kerriae'') is a type of
tinamou found in lowland forest and
montane forest in subtropical and tropical regions of
Colombia
Colombia (, ; ), officially the Republic of Colombia, is a country in South America with insular regions in North America—near Nicaragua's Caribbean coast—as well as in the Pacific Ocean. The Colombian mainland is bordered by the Car ...
and
Panama.
Description
The Choco tinamou is approximately in length. It is a small, plain dark
tinamou. Its upperparts are dark brown, with blackish crown, slate-grey sides of neck, whitish throat and indistinct dusky barring. Its legs are red. The females are darker with coarser barring on wing-coverts and breast, and grey flanks.
[BirdLife International (2008)]
Behavior
It has a low, faint, mournful, three-note whistle voice.
Like other tinamous, the Choco 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.
Taxonomy
The Choco tinamou is a monotypic species.
[Clements, J (2007)] All tinamou are from the family Tinamidae, and in the larger scheme are also
ratite
A ratite () is any of a diverse group of flightless, large, long-necked, and long-legged birds of the infraclass Palaeognathae. Kiwi, the exception, are much smaller and shorter-legged and are the only nocturnal extant ratites.

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.
[Davies, S. J. J. F. (2003)]
Etymology
''Crypturellus'' 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.

Habitat
The Choco tinamou resides in tropical and sub-tropical moist evergreen
forests both lowland and
montane up to altitude. However, it seems that it prefers higher elevations.
Threats
The Choco tinamou is currently threatened by the vast
destruction of its habitats caused by
road construction,
human settlement,
timber extraction and
mining. The completion of a new road-bridge has made unprotected areas of coastal plain forest adjacent to the
Ensenada de Utría National Park accessible to settlement and further threatens its habitats. The population at Atrato valley, Colombia, would probably be the most threatened caused by human settlement, and
conversion to farmland
Land development is the alteration of landscape in any number of ways such as:
* Changing landforms from a natural or semi-natural state for a purpose such as agriculture or House, housing
* subdivision (land), Subdividing real estate into Lot (re ...
and
banana plantations. It is presumably hunted wherever humans are present. The completion of the
Pan-American highway through
Darién and the canalisation of the Truandó and lower
Atrato Rivers, to make an inter-oceanic fairway, are currently on hold, but could have serious effects on the species if it is to be completed. The biggest threats are hunting, and the on-hold transportation plans.
Conservation measures
The Choco tinamou is currently protected in
Darién National Park, Panama, and Ensenada de Utría National Park, Colombia.
