Habitat Comparison
Cinereous Tinamou
Lowland humid forest and forest edges in the Amazon and Orinoco basins from Venezuela and Colombia to Bolivia and central Brazil. Prefers dense understorey near water. Tolerates some secondary growth.
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
Cinereous Tinamou
A monotonous, deep whistle repeated at regular slow intervals. The call is a single, resonant 'whoooo' given from forest floor cover. Typical of lowland humid forest.
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
Cinereous Tinamou
Ranges through forests of Chile and adjacent western Argentina. Sedentary in temperate Valdivian forests from sea level to 1,500 m.
Ornate Tinamou

About These Birds
Cinereous Tinamou
A plain uniformly grey-brown tinamou with barred wings and a pale throat. Widespread in lowland Amazonian and Orinoco basin forests. Often detected by its loud two-note whistle. Males alone incubate the glossy teal-colored eggs. Feeds on fallen fruits, seeds, and invertebrates.
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.
