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.
Pale-browed Tinamou
Seasonally dry tropical forest and deciduous scrub below 1,000 m in the Tumbesian bioregion of western Ecuador and northwestern Peru. Tolerates degraded habitats. Most active in early mornings.
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.
Pale-browed Tinamou
A hesitant, soft whistle repeated at long intervals. Considered a quieter tinamou; its pale-browed plumage matches its retiring vocal behavior in dry forest.
Geographic Range & Migration
Barred Tinamou
Inhabits savannas and forest edges of northeastern Brazil's semi-arid Caatinga region. Sedentary and endemic to this biome.
Pale-browed Tinamou
Inhabits forests and forest edges from Mexico to Ecuador and Bolivia. Largely sedentary; locally common in humid foothills.
