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.
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.

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.
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.

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.
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.
