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.
Black Tinamou
Humid cloud forest at 1,000–1,800 m in the Andes of southwestern Colombia and northern Peru. Favors steep terrain with dense undergrowth and mossy forest floor. Extremely range-restricted and rarely observed.
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.
Black Tinamou
A deep, resonant, single-note whistle with a sad, hollow quality. Poorly documented due to its remote Peruvian cloud forest habitat. Calls infrequently compared to other large tinamous.
Geographic Range & Migration
Bartlett's Tinamou
Ranges from southern Mexico through Central America to northern South America. Sedentary in humid lowland forest understory.
Black Tinamou
Inhabits tropical and subtropical forests from southern Mexico to Bolivia and central Brazil. Largely sedentary across its wide range.
