High-altitude puna grassland, scrubby slopes, and rocky terrain at 3,500–5,000 m in the Andes of Peru. Strongly associated with puna bunchgrass and cushion plant zones.
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
Taczanowski's Tinamou
A slow, mournful whistle from Andean puna grassland. Considered a quieter and less frequently heard tinamou; its VU status reflects range contraction and population decline.
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.
