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.
Highland Tinamou
Humid montane and cloud forest at 1,000–2,500 m in the Andes from Venezuela and Colombia south to Bolivia. Favors dense undergrowth with mossy ground cover near streams. Makes slight downhill movements in winter.
Song & Call Comparison
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.
Highland Tinamou
A series of clear, flute-like whistles at varying pitches. The call descends in scale, creating a melancholic phrase. Sings from dense Andean cloud forest understory.

Little Tinamou
Endemic to subtropical forests of northwestern Argentina, southeastern Bolivia, and adjacent Paraguay. Non-migratory; range restricted.
Highland Tinamou
Found in dense forests and thickets from Colombia and Venezuela to Argentina. Sedentary; locally common in humid lowland forests.
