Humid forest and scrub on tepui highlands at 1,000–2,000 m in the Gran Sabana region of Venezuela. Extremely restricted to isolated table-mountain plateaus. Rarely studied or observed.
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
Tepui Tinamou
