Habitat Comparison
Hooded Tinamou
Dense humid montane forest at 2,000–3,000 m in the Andes of Bolivia and Peru. Favors moist steep terrain with thick fern cover and rocky outcrops. Rarely recorded far from dense forest.
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
Hooded Tinamou
A repeated hollow whistle with a slightly quavering quality. The call is 'wheeooo-wheeooo' given slowly from dense highland undergrowth. Rarely heard except at dusk.
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
Hooded Tinamou
Restricted to wet forests and savannas of Patagonia in southern Chile and Argentina. Locally sedentary; some altitudinal movements.
Solitary Tinamou
Restricted to Paraguay, southern Bolivia, and northern Argentina. Sedentary in dry Chaco woodlands and open grasslands year-round.

About These Birds
Hooded Tinamou
A medium-sized tinamou notable for its black crown and nape contrasting with rufous-brown body plumage. Found in humid montane forests of the central Andes. Terrestrial and elusive; detected most easily by its loud clear whistle at dawn and dusk. Forages for fruits and invertebrates.
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.
