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.
Highland Tinamou
Humid montane and cloud forest at 1,000–2,500 m in the Andes from Venezuela and Colombia south to Bolivia. Favors dense undergrowth with mossy ground cover near streams. Makes slight downhill movements in winter.

Highland Tinamou
A series of clear, flute-like whistles at varying pitches. The call descends in scale, creating a melancholic phrase. Sings from dense Andean cloud forest understory.
