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.
Puna Tinamou
A high-pitched, clear whistle from high Andean puna. Call carries through the thin air of altiplano above 4,000 m elevation. Among the highest-dwelling tinamou species.

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.
Puna Tinamou
A large robustly built tinamou with grey-brown streaked plumage and a slightly crested head. The only tinamou with a vestigial crest. Found on high Andean puna and altiplano. Gregarious, foraging in flocks on bunchgrass plains and rocky hillsides.
