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.
Cinereous Tinamou
Lowland humid forest and forest edges in the Amazon and Orinoco basins from Venezuela and Colombia to Bolivia and central Brazil. Prefers dense understorey near water. Tolerates some secondary growth.
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.
Cinereous Tinamou
A monotonous, deep whistle repeated at regular slow intervals. The call is a single, resonant 'whoooo' given from forest floor cover. Typical of lowland humid forest.
Geographic Range & Migration
Barred Tinamou
Inhabits savannas and forest edges of northeastern Brazil's semi-arid Caatinga region. Sedentary and endemic to this biome.
Cinereous Tinamou
Ranges through forests of Chile and adjacent western Argentina. Sedentary in temperate Valdivian forests from sea level to 1,500 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.
Cinereous Tinamou
A plain uniformly grey-brown tinamou with barred wings and a pale throat. Widespread in lowland Amazonian and Orinoco basin forests. Often detected by its loud two-note whistle. Males alone incubate the glossy teal-colored eggs. Feeds on fallen fruits, seeds, and invertebrates.
