Habitat Comparison
Black-capped Tinamou
Humid foothill and lower montane forest at 250–1,200 m on the eastern Andean slopes from southern Colombia to Bolivia. Prefers dense undergrowth with mossy forest floor near streams.
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
Black-capped Tinamou
A deep, hollow whistle repeated slowly. Considered vocally similar to Variegated Tinamou but delivers its call from Andean foothill forest at lower elevations.
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.

Black-capped Tinamou
Found in arid scrublands and dry woodlands of Peru and Bolivia. Sedentary; restricted to western slope Andean valleys below 2,500 m.
