Habitat Comparison
Bartlett's Tinamou
Lowland humid forest in the western Amazon basin of Peru, Ecuador, and adjacent Colombia and Brazil. Prefers undisturbed terra firme and seasonally flooded forest interior below 400 m.
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
Bartlett's Tinamou
A soft, repeated whistle from Amazonian lowland forest. Less well known than other Crypturellus; its call is a simple 2-note descending whistle given from dense cover.
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
Bartlett's Tinamou
Ranges from southern Mexico through Central America to northern South America. Sedentary in humid lowland forest understory.

About These Birds
Bartlett's Tinamou
A small brown tinamou with obscure barring and a grey throat, named after naturalist Edward Bartlett. Found in the western Amazon basin in Peru, Ecuador, and adjacent Brazil. Terrestrial and cryptic; detected mainly by its soft clear whistle in humid 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.
