Habitat Comparison
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.
Great Tinamou
Humid lowland and foothill tropical rainforest from southern Mexico through Central America to Bolivia and southeastern Brazil. Prefers undisturbed forest interior with dense understorey. Nests on the ground.
Song & Call Comparison
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.
Great Tinamou
A beautiful, pure whistled phrase repeated at regular intervals from the forest floor. Call is a clear 'wheeeoo-wheeeoo'. Among the most musical tinamou calls in its range.

About These Birds
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.
Great Tinamou
The largest regularly occurring tinamou, with brownish-grey plumage, barred wings, and a pale belly. Common in lowland Neotropical rainforest from Mexico to Bolivia. Males incubate glossy teal-colored eggs. Their haunting multi-note calls resonate through the forest, making them acoustically conspicuous yet visually elusive.
