Habitat Comparison
Ornate Tinamou
High puna grassland, rocky outcrops, and shrubby slopes at 3,000–4,800 m in the Andes from Peru through Bolivia to northwestern Argentina and Chile. Often near rocky gullies and streams.
Grey Tinamou
Tropical and subtropical humid montane forest from Venezuela and Colombia south to Bolivia and northern Brazil at 200–1,800 m. Favors dense undergrowth near forest streams. Nests on the ground among leaf litter.
Song & Call Comparison

A musical, clear whistle from Andean puna and bofedales. Call is a repeated 2-note phrase. Considered one of the more melodic high-elevation tinamous in the genus.
Grey Tinamou
A series of haunting, flute-like hollow whistles 'whooo-wooo' delivered at dawn and dusk from within humid forest. Mournful, far-carrying quality typical of large forest tinamous.

Ornate Tinamou
Ranges along Pacific slopes of the Andes from Ecuador to central Chile. Sedentary in arid and semi-arid foothill scrub.
Grey Tinamou
