Cerrado woodland, savanna grassland, gallery forest edges, and campo sujo in central Brazil, Bolivia, and Paraguay. Tolerates degraded habitats and cultivated areas. Most common in open and transitional zones.
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

A high-pitched whistle with minimal variation. Among the smaller tinamous; call reflects its tiny size with a thinner tone. Found in open Cerrado grassland-forest edge.
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.

About These Birds
Small-billed Tinamou
A small tinamou with brown plumage, pale underparts, and a notably short fine bill. Widespread in cerrado, savanna woodlands, and forest edges of central South America. Often calls from dense grass or low scrub. One of the few tinamous adapted to open and semi-open habitats.
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.
