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.
Hooded Tinamou
Dense humid montane forest at 2,000–3,000 m in the Andes of Bolivia and Peru. Favors moist steep terrain with thick fern cover and rocky outcrops. Rarely recorded far from dense 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.
Hooded Tinamou
A repeated hollow whistle with a slightly quavering quality. The call is 'wheeooo-wheeooo' given slowly from dense highland undergrowth. Rarely heard except at dusk.
Geographic Range & Migration
Barred Tinamou
Inhabits savannas and forest edges of northeastern Brazil's semi-arid Caatinga region. Sedentary and endemic to this biome.
Hooded Tinamou

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.
Hooded Tinamou
A medium-sized tinamou notable for its black crown and nape contrasting with rufous-brown body plumage. Found in humid montane forests of the central Andes. Terrestrial and elusive; detected most easily by its loud clear whistle at dawn and dusk. Forages for fruits and invertebrates.
