Habitat Comparison
Black-capped Tinamou
Humid foothill and lower montane forest at 250–1,200 m on the eastern Andean slopes from southern Colombia to Bolivia. Prefers dense undergrowth with mossy forest floor near streams.
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.
Song & Call Comparison
Black-capped Tinamou
A deep, hollow whistle repeated slowly. Considered vocally similar to Variegated Tinamou but delivers its call from Andean foothill forest at lower elevations.
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.
Geographic Range & Migration
Black-capped Tinamou
Found in arid scrublands and dry woodlands of Peru and Bolivia. Sedentary; restricted to western slope Andean valleys below 2,500 m.
Barred Tinamou
Inhabits savannas and forest edges of northeastern Brazil's semi-arid Caatinga region. Sedentary and endemic to this biome.

About These Birds
Black-capped Tinamou
