About These Birds
White-bellied Nothura
A small tinamou of open caatinga and cerrado grasslands, with brown streaked plumage and white underparts. Endemic to northeastern Brazil. Adapted to hot dry and semi-arid environments. Calls with a rapid whistling trill. Terrestrial and fast-running across sparse scrub.
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.
