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.
Brushland Tinamou
Dry brushland, thorny scrub, and chaco woodland in Bolivia, Paraguay, and northwestern Argentina. Prefers hot semi-arid environments with sparse tree cover and dense ground vegetation.
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.
Brushland Tinamou
A low, repeated whistle from dry Chaco scrub. Call is unremarkable — a simple repeated note. Cryptic and secretive; the call is often the only indication of presence.
Geographic Range & Migration
Barred Tinamou
Inhabits savannas and forest edges of northeastern Brazil's semi-arid Caatinga region. Sedentary and endemic to this biome.
Brushland Tinamou
Found on the Pacific slopes of the Andes from Colombia to northern Chile. Sedentary in dense cloud forest between 800–2,500 m.

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.
Brushland Tinamou
A medium-sized plainly colored tinamou with grey-brown plumage and subtle barring. Found in dry brushland and thorny scrub of the Gran Chaco and Pampas regions. Terrestrial and secretive; calls infrequently. Adapted to arid and semi-arid open habitats of central South America.
