About These Birds
Darwin's Nothura
A small tinamou named in honor of Charles Darwin, with streaked brown plumage and pale underparts. Common in puna grasslands and Andean steppe of Peru, Bolivia, Chile, and Argentina. Terrestrial and gregarious; moves in small groups. Calls with a rapid trilling whistle.
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.
