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.

About These Birds
Tepui Tinamou
A small little-known tinamou with dark brown plumage confined to the tepui highlands of southern Venezuela. Known from very few specimens. Terrestrial and secretive; its call is rarely heard. Forages in dense submontane and montane forest undergrowth.
Solitary Tinamou
A large heavily built tinamou with dark olive-brown upperparts, pale underparts, and distinctive dark barring. Lives singly in dense Atlantic Forest, rarely seen despite its loud melancholic calls. Feeds on fallen fruit, seeds, and invertebrates. Threatened by deforestation across eastern Brazil.
