Habitat Comparison
Undulated Tinamou
Humid forests, forest edges, cerrado woodland, and gallery forest in the Amazon basin and adjacent cerrado from Venezuela and Colombia to Argentina. Tolerates seasonally flooded forest and disturbed secondary habitats.
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
Undulated Tinamou
A loud, repeated undulating whistle that rises and falls — matching its name 'undulated'. Carries well through várzea forest and wetland edges across its broad range.
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
Undulated Tinamou
Found in scrubby hillsides and forest edges from Mexico south through Central America to Honduras. Sedentary at low to mid elevations.
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
Undulated Tinamou
A medium-sized tinamou with fine undulating barring throughout its brown plumage, giving it a scalloped look. Widespread in Amazonian and Cerrado habitats. Produces a distinctive three- or four-note fluted call. Feeds on fallen fruits, arthropods, and seeds, often near gallery forests and water.
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.
