Curve-billed Tinamou only
Solitary Tinamou only
Curve-billed Tinamou
High puna grassland, paramo, and scrubby slopes at 3,000–4,500 m in the Andes of Ecuador and northern Peru. Associated with wet paramo, cushion bogs, and rocky terrain.
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
Curve-billed Tinamou
A soft, falling 2-note whistle from Andean cloud forest edges. Carries well through mist-shrouded vegetation. Considered a quieter species overall among highland tinamous.
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
Curve-billed Tinamou
Restricted to the Atlantic Forest of southeastern Brazil (Rio de Janeiro, São Paulo, Minas Gerais). Sedentary; critically threatened.
Solitary Tinamou
Restricted to Paraguay, southern Bolivia, and northern Argentina. Sedentary in dry Chaco woodlands and open grasslands year-round.

About These Birds
Curve-billed Tinamou
A small compact tinamou with a notably long decurved bill, brown-streaked plumage, and pale underparts. Found in high Andean grasslands in Ecuador and Peru. The curved bill is adapted to probing soil for invertebrates and tubers in puna habitats.
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.
