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.
Geographic Range & Migration
Yellow-legged Tinamou
Inhabits humid forests of eastern Brazil from Bahia to Rio Grande do Sul. Sedentary; restricted to Atlantic Forest remnants.
Solitary Tinamou
Restricted to Paraguay, southern Bolivia, and northern Argentina. Sedentary in dry Chaco woodlands and open grasslands year-round.

About These Birds
Yellow-legged Tinamou
A medium-sized tinamou with yellow-orange legs, dark brown upperparts, and pale underparts. Endemic to the Atlantic Forest of eastern Brazil. Largely nocturnal; its mournful whistle is often heard at night. Threatened by continuing deforestation of the Atlantic Forest.
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.
