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.
Lesser Nothura
Native campo sujo and campo limpo grasslands of the cerrado biome in central Brazil. Highly dependent on intact native grassland with bunchgrass structure; very sensitive to exotic grass invasion and burning.
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.
Lesser Nothura
A thin, high whistle, poorly documented due to its vulnerable status and restricted campos habitat in interior Brazil. Rarely recorded; calls are considered similar to Spotted Nothura.

Curve-billed Tinamou
Restricted to the Atlantic Forest of southeastern Brazil (Rio de Janeiro, São Paulo, Minas Gerais). Sedentary; critically threatened.
Lesser Nothura
Found in open grassy habitats of central South America from Bolivia and Brazil to Argentina. Sedentary; forages in short grassland.

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.
Lesser Nothura
A very small tinamou with finely streaked brown plumage and whitish underparts. One of the smallest tinamous. Restricted to the cerrado campos and grasslands of central Brazil. Critically Endangered due to loss of native cerrado. Calls with a thin high-pitched whistle.
