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.
Geographic Range & Migration
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.

About These Birds
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.
Highland Tinamou
A medium-sized tinamou with dark brown upperparts, rufous-streaked breast, and a long slightly decurved bill. Inhabits Andean cloud forests. Its rich plaintive whistle is heard more often than the bird itself. Feeds on berries, seeds, and invertebrates on damp mossy forest floors.
