Habitat Comparison
Puna Tinamou
Open puna grassland, bunchgrass plains, and rocky hillsides at 3,500–5,000 m in the Andes from Peru through Bolivia to northern Chile and northwestern Argentina.
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
Puna Tinamou
A high-pitched, clear whistle from high Andean puna. Call carries through the thin air of altiplano above 4,000 m elevation. Among the highest-dwelling tinamou species.
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
Puna Tinamou
Inhabits marshes and wetland edges across the Southern Cone; from southeastern Brazil to Patagonian Argentina. Partially migratory.
Solitary Tinamou
Restricted to Paraguay, southern Bolivia, and northern Argentina. Sedentary in dry Chaco woodlands and open grasslands year-round.

About These Birds
Puna Tinamou
A large robustly built tinamou with grey-brown streaked plumage and a slightly crested head. The only tinamou with a vestigial crest. Found on high Andean puna and altiplano. Gregarious, foraging in flocks on bunchgrass plains and rocky hillsides.
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.
