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.
Solitary Tinamou
A large heavily built tinamou with dark olive-brown upperparts, pale underparts, and distinctive dark barring. Lives singly in dense Atlantic Forest, rarely seen despite its loud melancholic calls. Feeds on fallen fruit, seeds, and invertebrates. Threatened by deforestation across eastern Brazil.
