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.
Darwin's Nothura
Puna grassland, Andean steppe, and altiplano at 3,000–4,500 m from Peru through Bolivia and Chile to central Argentina. Tolerates dry exposed conditions and some human disturbance.
Song & Call Comparison
Ornate Tinamou
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.
Darwin's Nothura
A fast, rippling 3-note whistle from puna grassland and desert scrub. Call is considered brighter and faster than related nothuras. Heard during morning and evening activity.
Geographic Range & Migration
Ornate Tinamou
Ranges along Pacific slopes of the Andes from Ecuador to central Chile. Sedentary in arid and semi-arid foothill scrub.
Darwin's Nothura
