Habitat Comparison
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.
Andean Tinamou
Andean valleys, foothills, scrubby slopes, and agricultural land at 1,500–4,000 m from Ecuador through Peru and Bolivia to northwestern Argentina. Tolerates degraded and cultivated areas with scrub remnants.
Song & Call Comparison

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.
Andean Tinamou
A rising 2-note whistle from Andean scrub and grassland. Frequently heard during early morning. Considered a vocal species within its highland habitat.
Geographic Range & Migration
Little Tinamou
Endemic to subtropical forests of northwestern Argentina, southeastern Bolivia, and adjacent Paraguay. Non-migratory; range restricted.
Andean Tinamou
Inhabits forests and edges in a broad arc from Costa Rica to northern Argentina and southeastern Brazil. Largely sedentary.
