About These Birds
Cinereous Tinamou
A plain uniformly grey-brown tinamou with barred wings and a pale throat. Widespread in lowland Amazonian and Orinoco basin forests. Often detected by its loud two-note whistle. Males alone incubate the glossy teal-colored eggs. Feeds on fallen fruits, seeds, and invertebrates.
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.
