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.
Black Tinamou
Humid cloud forest at 1,000–1,800 m in the Andes of southwestern Colombia and northern Peru. Favors steep terrain with dense undergrowth and mossy forest floor. Extremely range-restricted and rarely observed.

Black Tinamou
A deep, resonant, single-note whistle with a sad, hollow quality. Poorly documented due to its remote Peruvian cloud forest habitat. Calls infrequently compared to other large tinamous.

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.
Black Tinamou
A large darkly colored tinamou with blackish-brown plumage and pale spotting on the wings. One of the least-known tinamou species, inhabiting cloud forests in Colombia and Peru. Terrestrial and secretive; rarely observed. Known primarily from specimens and occasional recordings.
