Habitat Comparison
Black Tinamou
Humid cloud forest at 1,000–1,800 m in the Andes of southwestern Colombia and northern Peru. Favors steep terrain with dense undergrowth and mossy forest floor. Extremely range-restricted and rarely observed.
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
Black Tinamou
A deep, resonant, single-note whistle with a sad, hollow quality. Poorly documented due to its remote Peruvian cloud forest habitat. Calls infrequently compared to other large tinamous.
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
Black Tinamou
Inhabits tropical and subtropical forests from southern Mexico to Bolivia and central Brazil. Largely sedentary across its wide range.
Solitary Tinamou
Restricted to Paraguay, southern Bolivia, and northern Argentina. Sedentary in dry Chaco woodlands and open grasslands year-round.

About These Birds
Black Tinamou
A large darkly colored tinamou with blackish-brown plumage and pale spotting on the wings. One of the least-known tinamou species, inhabiting cloud forests in Colombia and Peru. Terrestrial and secretive; rarely observed. Known primarily from specimens and occasional recordings.
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.
