About These Birds
Yellow-legged Tinamou
A medium-sized tinamou with yellow-orange legs, dark brown upperparts, and pale underparts. Endemic to the Atlantic Forest of eastern Brazil. Largely nocturnal; its mournful whistle is often heard at night. Threatened by continuing deforestation of the Atlantic Forest.
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.
