About These Birds
Puna Tinamou
A large robustly built tinamou with grey-brown streaked plumage and a slightly crested head. The only tinamou with a vestigial crest. Found on high Andean puna and altiplano. Gregarious, foraging in flocks on bunchgrass plains and rocky hillsides.
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.
