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.

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.
White-throated Tinamou
A medium-large tinamou with bold white spotting on brown upperparts and a distinctive white throat patch. Found in lowland Amazonian rainforest. Its resonant flute-like call is one of the signature sounds of Amazonian forests. Feeds on fallen fruits, seeds, and invertebrates on the forest floor.
