Habitat Comparison
Grey-legged Tinamou
Montane forest and shrubby tepui slopes at 600–1,800 m on isolated table-mountains in southern Venezuela and adjacent northern Brazil. Restricted range; known from very few locations.
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
Grey-legged Tinamou
A series of hollow whistles with a slightly husky tone. Calls from dense forest floor cover in tepui foothills. Considered vocally conservative among Crypturellus tinamous.
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
Grey-legged Tinamou
Endemic to the humid Andean slopes of western Colombia and northwestern Ecuador. Sedentary in cloud forest from 800 to 2,200 m.
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
Grey-legged Tinamou
A poorly known medium-sized tinamou with brown plumage and conspicuously grey legs. Restricted to the tepui region of southern Venezuela and adjacent northern Brazil. Known from very few observations. Forages terrestrially in dense undergrowth of montane 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.
