Habitat Comparison
Choco Tinamou
Dense humid lowland forest in the Darién region of eastern Panama and Chocó of Colombia, below 300 m. Extremely restricted to this narrow Pacific bioregion. Rarely encountered even by experienced field ornithologists.
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
Choco Tinamou
A soft, hesitant whistle from dense Choco rainforest — one of the most poorly documented tinamou calls, reflecting its restricted and threatened lowland Pacific rainforest 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
Choco Tinamou
Inhabits open grasslands and steppes of Patagonian Argentina and Chile. Largely sedentary; some seasonal 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
Choco Tinamou
A small dark tinamou with black-barred olive-brown plumage. One of the least-known tinamous in the world, restricted to the Chocó bioregion of Colombia and Panama. Known from very few specimens; virtually unstudied in the field. Inhabits dense lowland Pacific forest.
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.
