Cinereous Tinamou
A monotonous, deep whistle repeated at regular slow intervals. The call is a single, resonant 'whoooo' given from forest floor cover. Typical of lowland humid forest.

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.
Cinereous Tinamou
A plain uniformly grey-brown tinamou with barred wings and a pale throat. Widespread in lowland Amazonian and Orinoco basin forests. Often detected by its loud two-note whistle. Males alone incubate the glossy teal-colored eggs. Feeds on fallen fruits, seeds, and invertebrates.
