Habitat Comparison
Brazilian Tinamou
Dense lowland terra firme and seasonally flooded várzea rainforest in central and eastern Amazonian Brazil. Favors undisturbed forest interior with dense leaf litter and undergrowth.
Solitary Tinamou
Dense Atlantic Forest of eastern Brazil from Bahia south to Rio Grande do Sul, into northeastern Argentina and Paraguay. Prefers humid lowland and foothill forest with closed canopy and thick undergrowth. Below 900 m.
Song & Call Comparison
Brazilian Tinamou
A series of pure, resonant whistles from Amazonian terra firme forest. Call is similar to other lowland Crypturellus but slightly rougher in quality.
Solitary Tinamou
Delivers a pure, mournful flute-like whistle repeated slowly. The call is a single clear 'whooo' rising then falling, given from dense understory. Less frequently heard than other tinamous.

Brazilian Tinamou
Ranges through forests from southern Mexico to Bolivia and central Brazil. Sedentary in dense lowland and foothill forest undergrowth.

About These Birds
Brazilian Tinamou
A small rufous-brown tinamou with fine pale streaking on its breast. Endemic to the Amazon basin of Brazil and adjacent areas. Terrestrial and secretive. Its clear fluted whistle is often the only indication of its presence in dense rainforest undergrowth.
Solitary Tinamou
A large heavily built tinamou with dark olive-brown upperparts, pale underparts, and distinctive dark barring. Lives singly in dense Atlantic Forest, rarely seen despite its loud melancholic calls. Feeds on fallen fruit, seeds, and invertebrates. Threatened by deforestation across eastern Brazil.
