Habitat Comparison
Yellow-legged Tinamou
Atlantic Forest remnants in eastern Brazil from Bahia south to Rio Grande do Sul. Prefers humid lowland and foothill forest with dense understorey. Increasingly restricted to forest fragments due to deforestation.
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.
Song & Call Comparison
Yellow-legged Tinamou
A slow, clear, somewhat melancholic whistle repeated at intervals. Nocturnal calling behavior makes it easier to hear than to see in Atlantic Forest and Cerrado.
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.
Geographic Range & Migration
Yellow-legged Tinamou
Inhabits humid forests of eastern Brazil from Bahia to Rio Grande do Sul. Sedentary; restricted to Atlantic Forest remnants.
Ornate Tinamou
Ranges along Pacific slopes of the Andes from Ecuador to central Chile. Sedentary in arid and semi-arid foothill scrub.

About These Birds
Yellow-legged Tinamou
A medium-sized tinamou with yellow-orange legs, dark brown upperparts, and pale underparts. Endemic to the Atlantic Forest of eastern Brazil. Largely nocturnal; its mournful whistle is often heard at night. Threatened by continuing deforestation of the Atlantic Forest.
Ornate Tinamou
A striking medium-sized tinamou with intricately patterned brown, black, and white plumage—one of the most ornately marked tinamou species. Found in Andean puna from Peru to Argentina. Terrestrial and gregarious, often found in small flocks. Calls with a clear fluted whistle.
