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.

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