Black-capped Tinamou

The black-capped tinamou is approximately 28 to 30 cm (11–12 in) in length. Its upper-parts are brown, mottled and barred blackish, throat and neck are rufescent, breast is dark grey, and the remainder of underparts are cinnamon to buff. Its cap is blackish and legs could be pale red or bright red. The females are more heavily barred above.

It is found in moist forest lowlands in subtropical and tropical regions up to 900 m (3,000 ft) altitude. This species is native to southeastern Peru and northern Bolivia. It has recently been recorded in Brazil.

Like other tinamous, the black-capped 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.

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.
