About These Birds
Brown Tinamou
A medium-sized dark brown tinamou with paler underparts, barred flanks, and a red bill. Widespread through Atlantic Forest and humid Andean slopes. Its loud mournful whistle is a familiar sound in foothill forests. Omnivorous, eating fruits, seeds, and invertebrates on the forest floor.
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.
