About These Birds
Bartlett's Tinamou
A small brown tinamou with obscure barring and a grey throat, named after naturalist Edward Bartlett. Found in the western Amazon basin in Peru, Ecuador, and adjacent Brazil. Terrestrial and cryptic; detected mainly by its soft clear whistle in humid forest.
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.
