About These Birds
Tepui Tinamou
A small little-known tinamou with dark brown plumage confined to the tepui highlands of southern Venezuela. Known from very few specimens. Terrestrial and secretive; its call is rarely heard. Forages in dense submontane and montane forest undergrowth.
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.
