Bartlett's Tinamou
Lowland humid forest in the western Amazon basin of Peru, Ecuador, and adjacent Colombia and Brazil. Prefers undisturbed terra firme and seasonally flooded forest interior below 400 m.
Variegated Tinamou
Lowland humid tropical forest in the Amazon basin, from southern Venezuela and the Guianas through Peru, Bolivia, and central Brazil. Prefers undisturbed forest interior, tolerating some várzea and forest edge.

Variegated Tinamou
A clear, loud whistle of 2-3 falling notes. Called variably from lowland Amazonian forest. One of the more frequently encountered and identified Crypturellus in its range.

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.
Variegated Tinamou
A medium-sized tinamou with heavily patterned plumage—chestnut, black, and buff barring—making it one of the most intricately patterned tinamous. Found throughout Amazonia. Its loud rolling whistle carries through the forest. Feeds on fruits and invertebrates in forest undergrowth.
