Habitat Comparison
Pale-browed Tinamou
Seasonally dry tropical forest and deciduous scrub below 1,000 m in the Tumbesian bioregion of western Ecuador and northwestern Peru. Tolerates degraded habitats. Most active in early mornings.
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
Pale-browed Tinamou
A hesitant, soft whistle repeated at long intervals. Considered a quieter tinamou; its pale-browed plumage matches its retiring vocal behavior in dry forest.
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
Pale-browed Tinamou
Inhabits forests and forest edges from Mexico to Ecuador and Bolivia. Largely sedentary; locally common in humid foothills.
Solitary Tinamou
Restricted to Paraguay, southern Bolivia, and northern Argentina. Sedentary in dry Chaco woodlands and open grasslands year-round.
