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.
Solitary Tinamou
Dense Atlantic Forest of eastern Brazil from Bahia south to Rio Grande do Sul, into northeastern Argentina and Paraguay. Prefers humid lowland and foothill forest with closed canopy and thick undergrowth. Below 900 m.
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.
Solitary Tinamou
Delivers a pure, mournful flute-like whistle repeated slowly. The call is a single clear 'whooo' rising then falling, given from dense understory. Less frequently heard than other tinamous.
Geographic Range & Migration
Barred Tinamou
Inhabits savannas and forest edges of northeastern Brazil's semi-arid Caatinga region. Sedentary and endemic to this biome.
Solitary Tinamou
Restricted to Paraguay, southern Bolivia, and northern Argentina. Sedentary in dry Chaco woodlands and open grasslands year-round.

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.
Solitary Tinamou
A large heavily built tinamou with dark olive-brown upperparts, pale underparts, and distinctive dark barring. Lives singly in dense Atlantic Forest, rarely seen despite its loud melancholic calls. Feeds on fallen fruit, seeds, and invertebrates. Threatened by deforestation across eastern Brazil.
