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.
Lesser Nothura
Native campo sujo and campo limpo grasslands of the cerrado biome in central Brazil. Highly dependent on intact native grassland with bunchgrass structure; very sensitive to exotic grass invasion and burning.
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.
Lesser Nothura
A thin, high whistle, poorly documented due to its vulnerable status and restricted campos habitat in interior Brazil. Rarely recorded; calls are considered similar to Spotted Nothura.
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.
Lesser Nothura
Found in open grassy habitats of central South America from Bolivia and Brazil to Argentina. Sedentary; forages in short grassland.

About These Birds
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.
Lesser Nothura
A very small tinamou with finely streaked brown plumage and whitish underparts. One of the smallest tinamous. Restricted to the cerrado campos and grasslands of central Brazil. Critically Endangered due to loss of native cerrado. Calls with a thin high-pitched whistle.
