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.
Black Tinamou
Humid cloud forest at 1,000–1,800 m in the Andes of southwestern Colombia and northern Peru. Favors steep terrain with dense undergrowth and mossy forest floor. Extremely range-restricted and rarely observed.
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.
Black Tinamou
A deep, resonant, single-note whistle with a sad, hollow quality. Poorly documented due to its remote Peruvian cloud forest habitat. Calls infrequently compared to other large tinamous.

Barred Tinamou
Inhabits savannas and forest edges of northeastern Brazil's semi-arid Caatinga region. Sedentary and endemic to this biome.

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.
Black Tinamou
A large darkly colored tinamou with blackish-brown plumage and pale spotting on the wings. One of the least-known tinamou species, inhabiting cloud forests in Colombia and Peru. Terrestrial and secretive; rarely observed. Known primarily from specimens and occasional recordings.
