Habitat Comparison
Variegated Tinamou
Lowland humid tropical forest in the Amazon basin, from southern Venezuela and the Guianas through Peru, Bolivia, and central Brazil. Prefers undisturbed forest interior, tolerating some várzea and forest edge.
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.

About These Birds
Variegated Tinamou
A medium-sized tinamou with heavily patterned plumage—chestnut, black, and buff barring—making it one of the most intricately patterned tinamous. Found throughout Amazonia. Its loud rolling whistle carries through the forest. Feeds on fruits and invertebrates in forest undergrowth.
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.
