Habitat Comparison
Yellow-legged Tinamou
Atlantic Forest remnants in eastern Brazil from Bahia south to Rio Grande do Sul. Prefers humid lowland and foothill forest with dense understorey. Increasingly restricted to forest fragments due to deforestation.
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
Yellow-legged Tinamou
A slow, clear, somewhat melancholic whistle repeated at intervals. Nocturnal calling behavior makes it easier to hear than to see in Atlantic Forest and Cerrado.
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.
