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.
Little Tinamou
Forest edges, dense secondary growth, overgrown clearings, and thickets from sea level to 1,500 m, from southern Mexico through Central America and throughout tropical South America. Highly adaptable.
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.
Little Tinamou
A soft, high-pitched, repeated whistle — higher in pitch than most tinamous due to its small size. Song is 2-3 ascending notes. Gives thin alarm 'seet' when disturbed.
Geographic Range & Migration
Barred Tinamou
Inhabits savannas and forest edges of northeastern Brazil's semi-arid Caatinga region. Sedentary and endemic to this biome.
Little Tinamou
Endemic to subtropical forests of northwestern Argentina, southeastern Bolivia, and adjacent Paraguay. Non-migratory; range restricted.

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.
Little Tinamou
One of the smallest tinamous, with warm brown plumage, rufous underparts, and a red bill. Widespread from southern Mexico to Bolivia and central Brazil. Inhabits forest edges, thickets, and secondary growth in humid lowlands. Its loud ascending whistle carries far through dense vegetation.
