Habitat Comparison
Tepui Tinamou
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.
Solitary Tinamou
Dense Atlantic Forest of eastern Brazil from Bahia south to Rio Grande do Sul, into northeastern Argentina and Paraguay. Prefers humid lowland and foothill forest with closed canopy and thick undergrowth. Below 900 m.
Song & Call Comparison
Tepui Tinamou
A clear, whistled phrase from Tepui tabletop habitats. Call is a 2-note falling whistle. Poorly documented; restricted range makes systematic study difficult.
Solitary Tinamou
Delivers a pure, mournful flute-like whistle repeated slowly. The call is a single clear 'whooo' rising then falling, given from dense understory. Less frequently heard than other tinamous.
Geographic Range & Migration
Tepui Tinamou
Found in forests and scrub of southern Bolivia and northwestern Argentina. Sedentary; inhabits dry montane valleys at 1,500–3,000 m.
