Habitat Comparison
Barred Tinamou
Restricted to humid lowland forest along the Casiquiare canal region of southern Venezuela and extreme northwestern Brazil. Associated with river-edge and flooded forest at low elevations. Rarely recorded.
Yellow-legged Tinamou
Atlantic Forest remnants in eastern Brazil from Bahia south to Rio Grande do Sul. Prefers humid lowland and foothill forest with dense understorey. Increasingly restricted to forest fragments due to deforestation.
Song & Call Comparison
Barred Tinamou
A slow, hollow whistle from blackwater river forest of the upper Orinoco. Call is distinctive but rarely recorded given its restricted range on the Venezuela-Colombia border.
Yellow-legged Tinamou
A slow, clear, somewhat melancholic whistle repeated at intervals. Nocturnal calling behavior makes it easier to hear than to see in Atlantic Forest and Cerrado.
Geographic Range & Migration
Barred Tinamou
Inhabits savannas and forest edges of northeastern Brazil's semi-arid Caatinga region. Sedentary and endemic to this biome.
Yellow-legged Tinamou
Inhabits humid forests of eastern Brazil from Bahia to Rio Grande do Sul. Sedentary; restricted to Atlantic Forest remnants.

About These Birds
Barred Tinamou
A small tinamou with distinctly barred brown-and-buff plumage. Restricted to the Casiquiare region of Venezuela and adjacent northwestern Brazil—one of the most restricted tinamou ranges. Nearly all data come from specimens. Inhabits humid lowland forest along river systems.
Yellow-legged Tinamou
A medium-sized tinamou with yellow-orange legs, dark brown upperparts, and pale underparts. Endemic to the Atlantic Forest of eastern Brazil. Largely nocturnal; its mournful whistle is often heard at night. Threatened by continuing deforestation of the Atlantic Forest.
