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.
Solitary Tinamou
Dense Atlantic Forest of eastern Brazil from Bahia south to Rio Grande do Sul, into northeastern Argentina and Paraguay. Prefers humid lowland and foothill forest with closed canopy and thick undergrowth. Below 900 m.
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.
Solitary Tinamou
Delivers a pure, mournful flute-like whistle repeated slowly. The call is a single clear 'whooo' rising then falling, given from dense understory. Less frequently heard than other tinamous.
Geographic Range & Migration
Little Tinamou
Endemic to subtropical forests of northwestern Argentina, southeastern Bolivia, and adjacent Paraguay. Non-migratory; range restricted.
Solitary Tinamou
Restricted to Paraguay, southern Bolivia, and northern Argentina. Sedentary in dry Chaco woodlands and open grasslands year-round.

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.
Solitary Tinamou
A large heavily built tinamou with dark olive-brown upperparts, pale underparts, and distinctive dark barring. Lives singly in dense Atlantic Forest, rarely seen despite its loud melancholic calls. Feeds on fallen fruit, seeds, and invertebrates. Threatened by deforestation across eastern Brazil.
