About These Birds
Undulated Tinamou
A medium-sized tinamou with fine undulating barring throughout its brown plumage, giving it a scalloped look. Widespread in Amazonian and Cerrado habitats. Produces a distinctive three- or four-note fluted call. Feeds on fallen fruits, arthropods, and seeds, often near gallery forests and water.
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.
