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.
Grey-legged Tinamou
Montane forest and shrubby tepui slopes at 600–1,800 m on isolated table-mountains in southern Venezuela and adjacent northern Brazil. Restricted range; known from very few locations.
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.
Grey-legged Tinamou
A series of hollow whistles with a slightly husky tone. Calls from dense forest floor cover in tepui foothills. Considered vocally conservative among Crypturellus tinamous.
