Bartlett's Tinamou only
Curve-billed Tinamou only
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.
Curve-billed Tinamou
High puna grassland, paramo, and scrubby slopes at 3,000–4,500 m in the Andes of Ecuador and northern Peru. Associated with wet paramo, cushion bogs, and rocky terrain.
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.
Curve-billed Tinamou
A soft, falling 2-note whistle from Andean cloud forest edges. Carries well through mist-shrouded vegetation. Considered a quieter species overall among highland tinamous.
Geographic Range & Migration
Bartlett's Tinamou
Ranges from southern Mexico through Central America to northern South America. Sedentary in humid lowland forest understory.
Curve-billed Tinamou
Restricted to the Atlantic Forest of southeastern Brazil (Rio de Janeiro, São Paulo, Minas Gerais). Sedentary; critically threatened.

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.
Curve-billed Tinamou
A small compact tinamou with a notably long decurved bill, brown-streaked plumage, and pale underparts. Found in high Andean grasslands in Ecuador and Peru. The curved bill is adapted to probing soil for invertebrates and tubers in puna habitats.
