About These Birds
Quebracho Crested Tinamou
A small crested tinamou closely related to the Elegant Crested Tinamou, with a shorter crest and finer streaking. Found in dry chaco woodland of Paraguay, Bolivia, and Argentina. Terrestrial and gregarious. Poorly studied compared to its close relative.
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.
