About These Birds
Hooded Tinamou
A medium-sized tinamou notable for its black crown and nape contrasting with rufous-brown body plumage. Found in humid montane forests of the central Andes. Terrestrial and elusive; detected most easily by its loud clear whistle at dawn and dusk. Forages for fruits and invertebrates.
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.
