Habitat Comparison
Undulated Tinamou
Humid forests, forest edges, cerrado woodland, and gallery forest in the Amazon basin and adjacent cerrado from Venezuela and Colombia to Argentina. Tolerates seasonally flooded forest and disturbed secondary habitats.
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
Undulated Tinamou
A loud, repeated undulating whistle that rises and falls — matching its name 'undulated'. Carries well through várzea forest and wetland edges across its broad range.
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
Undulated Tinamou
Found in scrubby hillsides and forest edges from Mexico south through Central America to Honduras. Sedentary at low to mid elevations.
Solitary Tinamou
Restricted to Paraguay, southern Bolivia, and northern Argentina. Sedentary in dry Chaco woodlands and open grasslands year-round.

About These Birds
Undulated Tinamou
A medium-sized tinamou with fine undulating barring throughout its brown plumage, giving it a scalloped look. Widespread in Amazonian and Cerrado habitats. Produces a distinctive three- or four-note fluted call. Feeds on fallen fruits, arthropods, and seeds, often near gallery forests and water.
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.
