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.
Brown Tinamou
Humid forests from sea level to 2,200 m along the Andes and in Atlantic Forest of Brazil, Bolivia, Argentina, and Paraguay. Prefers dense forest interior and forest-edge thickets. Tolerates secondary forest.
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.
Brown Tinamou
A slow series of rich, whistled notes, descending or ascending. Call carries through secondary forest. One of the more musical tinamous in the Crypturellus genus.
Geographic Range & Migration

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.
Brown Tinamou
A medium-sized dark brown tinamou with paler underparts, barred flanks, and a red bill. Widespread through Atlantic Forest and humid Andean slopes. Its loud mournful whistle is a familiar sound in foothill forests. Omnivorous, eating fruits, seeds, and invertebrates on the forest floor.
