Habitat Comparison
Brushland Tinamou
Dry brushland, thorny scrub, and chaco woodland in Bolivia, Paraguay, and northwestern Argentina. Prefers hot semi-arid environments with sparse tree cover and dense ground vegetation.
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
Brushland Tinamou
A low, repeated whistle from dry Chaco scrub. Call is unremarkable — a simple repeated note. Cryptic and secretive; the call is often the only indication of presence.
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
Brushland Tinamou
Found on the Pacific slopes of the Andes from Colombia to northern Chile. Sedentary in dense cloud forest between 800–2,500 m.
Solitary Tinamou
Restricted to Paraguay, southern Bolivia, and northern Argentina. Sedentary in dry Chaco woodlands and open grasslands year-round.

About These Birds
Brushland Tinamou
A medium-sized plainly colored tinamou with grey-brown plumage and subtle barring. Found in dry brushland and thorny scrub of the Gran Chaco and Pampas regions. Terrestrial and secretive; calls infrequently. Adapted to arid and semi-arid open habitats of central South America.
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.
