About These Birds
Black-capped Tinamou
A small secretive tinamou with a dark black crown, rufous-brown body, and barred flanks. Found in foothill forests of the Andes from Colombia to Bolivia. Detected mainly by its soft whistle. Feeds on seeds, berries, and invertebrates in dense 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.
