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.
Dwarf Tinamou
Intact campo sujo and campo limpo grasslands of the cerrado in central Brazil. Extremely sensitive to burning, grazing, and conversion of native grasslands. One of the world's most poorly known birds.
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.
Dwarf Tinamou
Poorly documented; the Dwarf Tinamou is an endangered cerrado endemic whose call is a thin, very high-pitched whistle. Rarely recorded; secretive in tall grass.
Geographic Range & Migration
Barred Tinamou
Inhabits savannas and forest edges of northeastern Brazil's semi-arid Caatinga region. Sedentary and endemic to this biome.
Dwarf Tinamou
Found in the coastal Humboldt Current region of Peru and Chile. Largely sedentary; range closely tied to cold upwelling waters.

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.
Dwarf Tinamou
The smallest tinamou in the world, weighing only 40–50 g, with brown-streaked plumage and a very short bill. Critically Endangered and poorly known; restricted to intact cerrado grasslands of central Brazil. Considered one of South America's rarest and most enigmatic birds.
