Habitat Comparison
Highland Tinamou
Humid montane and cloud forest at 1,000–2,500 m in the Andes from Venezuela and Colombia south to Bolivia. Favors dense undergrowth with mossy ground cover near streams. Makes slight downhill movements in winter.
Dwarf Tinamou
Intact campo sujo and campo limpo grasslands of the cerrado in central Brazil. Extremely sensitive to burning, grazing, and conversion of native grasslands. One of the world's most poorly known birds.
Song & Call Comparison
Highland Tinamou
A series of clear, flute-like whistles at varying pitches. The call descends in scale, creating a melancholic phrase. Sings from dense Andean cloud forest understory.
Dwarf Tinamou
Poorly documented; the Dwarf Tinamou is an endangered cerrado endemic whose call is a thin, very high-pitched whistle. Rarely recorded; secretive in tall grass.
Geographic Range & Migration
Highland Tinamou
Found in dense forests and thickets from Colombia and Venezuela to Argentina. Sedentary; locally common in humid lowland forests.
Dwarf Tinamou
Found in the coastal Humboldt Current region of Peru and Chile. Largely sedentary; range closely tied to cold upwelling waters.

About These Birds
Highland Tinamou
A medium-sized tinamou with dark brown upperparts, rufous-streaked breast, and a long slightly decurved bill. Inhabits Andean cloud forests. Its rich plaintive whistle is heard more often than the bird itself. Feeds on berries, seeds, and invertebrates on damp mossy forest floors.
Dwarf Tinamou
The smallest tinamou in the world, weighing only 40–50 g, with brown-streaked plumage and a very short bill. Critically Endangered and poorly known; restricted to intact cerrado grasslands of central Brazil. Considered one of South America's rarest and most enigmatic birds.
