Habitat Comparison
White-bellied Nothura
Caatinga scrubland, dry cerrado grassland, and campo sujo of northeastern Brazil. Adapted to hot semi-arid habitats with sparse thorny vegetation. Often found on sandy soils.
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

A loud, melodic 3-note whistle from cerrado and dry scrub of interior Brazil. Considered one of the more vocal Nothura species; easily detected by call in its habitat.
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.

White-bellied Nothura
Inhabits wooded grasslands and forest edges of central Brazil, Bolivia, and Paraguay. Sedentary in the Cerrado biome.
