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.
Choco Tinamou
Dense humid lowland forest in the Darién region of eastern Panama and Chocó of Colombia, below 300 m. Extremely restricted to this narrow Pacific bioregion. Rarely encountered even by experienced field ornithologists.
Song & Call Comparison

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.
Choco Tinamou
A soft, hesitant whistle from dense Choco rainforest — one of the most poorly documented tinamou calls, reflecting its restricted and threatened lowland Pacific rainforest habitat.

About These Birds
Barred Tinamou
