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.
Little Tinamou
Forest edges, dense secondary growth, overgrown clearings, and thickets from sea level to 1,500 m, from southern Mexico through Central America and throughout tropical South America. Highly adaptable.
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.
Little Tinamou
A soft, high-pitched, repeated whistle — higher in pitch than most tinamous due to its small size. Song is 2-3 ascending notes. Gives thin alarm 'seet' when disturbed.
Geographic Range & Migration
Bartlett's Tinamou
Ranges from southern Mexico through Central America to northern South America. Sedentary in humid lowland forest understory.
Little Tinamou
Endemic to subtropical forests of northwestern Argentina, southeastern Bolivia, and adjacent Paraguay. Non-migratory; range restricted.

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.
Little Tinamou
One of the smallest tinamous, with warm brown plumage, rufous underparts, and a red bill. Widespread from southern Mexico to Bolivia and central Brazil. Inhabits forest edges, thickets, and secondary growth in humid lowlands. Its loud ascending whistle carries far through dense vegetation.
