Brown tinamou

The brown tinamou (Crypturellus obsoletus) is a brownish ground bird found in humid lowland and montane forest in tropical and subtropical South America.

The brown tinamou is approximately 25 to 30 cm (9.8–11.8 in) in length and it weighs about 350 to 550 g (12–19 oz). Depending on the subspecies involved, the upperparts vary from dark sooty-brown to bright chestnut and the underparts, which usually are paler than the upperparts, vary from chestnut to light ochraceous. The subspecies griseiventris is unique in having pale buff-grey underparts. All subspecies can be separated from the superficially similar little tinamou by the greyish (rather than whitish) throat. Females are typically larger and more rufescent than the males.
