Habitat Comparison
Andean Tinamou
Andean valleys, foothills, scrubby slopes, and agricultural land at 1,500–4,000 m from Ecuador through Peru and Bolivia to northwestern Argentina. Tolerates degraded and cultivated areas with scrub remnants.
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
Andean Tinamou
A rising 2-note whistle from Andean scrub and grassland. Frequently heard during early morning. Considered a vocal species within its highland habitat.
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
Andean Tinamou
Inhabits forests and edges in a broad arc from Costa Rica to northern Argentina and southeastern Brazil. Largely sedentary.
Solitary Tinamou
Restricted to Paraguay, southern Bolivia, and northern Argentina. Sedentary in dry Chaco woodlands and open grasslands year-round.

About These Birds
Andean Tinamou
A medium-sized tinamou with brown streaked plumage and pale supercilium. Widespread in Andean foothills and inter-Andean valleys from Ecuador to Argentina. Adaptable and locally common; inhabits a variety of open and scrubby habitats at mid to high altitudes.
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.
