About These Birds
Huayco Tinamou
A large tinamou with spotted brown-and-buff plumage, closely related to the Red-winged Tinamou. Found on Andean slopes and high-altitude grasslands in Bolivia and Peru. Less studied than its relative; inhabits dry puna scrub and rocky slopes.
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.
