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.
Highland Tinamou
Humid montane and cloud forest at 1,000–2,500 m in the Andes from Venezuela and Colombia south to Bolivia. Favors dense undergrowth with mossy ground cover near streams. Makes slight downhill movements in winter.
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.
Highland Tinamou
A series of clear, flute-like whistles at varying pitches. The call descends in scale, creating a melancholic phrase. Sings from dense Andean cloud forest understory.

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.
Highland Tinamou
A medium-sized tinamou with dark brown upperparts, rufous-streaked breast, and a long slightly decurved bill. Inhabits Andean cloud forests. Its rich plaintive whistle is heard more often than the bird itself. Feeds on berries, seeds, and invertebrates on damp mossy forest floors.
