About These Birds
Rusty Tinamou
A small tinamou with rich warm rufous-brown plumage and a short stout bill. Found in the central Amazon basin of Brazil. Poorly studied; known mainly from specimens and limited field encounters. Terrestrial and secretive, inhabiting the dense floor of Amazonian rainforest.
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.
