Habitat Comparison
Curve-billed Tinamou
High puna grassland, paramo, and scrubby slopes at 3,000–4,500 m in the Andes of Ecuador and northern Peru. Associated with wet paramo, cushion bogs, and rocky terrain.
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
Curve-billed Tinamou
A soft, falling 2-note whistle from Andean cloud forest edges. Carries well through mist-shrouded vegetation. Considered a quieter species overall among highland tinamous.

About These Birds
Curve-billed Tinamou
A small compact tinamou with a notably long decurved bill, brown-streaked plumage, and pale underparts. Found in high Andean grasslands in Ecuador and Peru. The curved bill is adapted to probing soil for invertebrates and tubers in puna habitats.
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.
