Habitat Comparison
Huayco Tinamou
Arid and semi-arid puna grassland, dry rocky slopes, and scrubby woodland at 2,500–4,000 m in the Andes of Bolivia and southern Peru. Often associated with dry quebrada 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
Huayco Tinamou
A slower, slightly lower whistle than the Red-winged Tinamou. Calls from steep scrubby Andean slopes. Relatively poorly documented compared to its lowland relatives.
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
Huayco Tinamou
Inhabits open savannas and grasslands from Colombia and Venezuela to Bolivia and southern Brazil. Sedentary; walks in tall grass.
Solitary Tinamou

About These Birds
Huayco Tinamou
A large tinamou with spotted brown-and-buff plumage, closely related to the Red-winged Tinamou. Found on Andean slopes and high-altitude grasslands in Bolivia and Peru. Less studied than its relative; inhabits dry puna scrub and rocky slopes.
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.
