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.
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.
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.
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.

Bartlett's Tinamou
Ranges from southern Mexico through Central America to northern South America. Sedentary in humid lowland forest understory.
Choco Tinamou
Inhabits open grasslands and steppes of Patagonian Argentina and Chile. Largely sedentary; some seasonal altitudinal movements.
