About These Birds
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.
Black Tinamou
A large darkly colored tinamou with blackish-brown plumage and pale spotting on the wings. One of the least-known tinamou species, inhabiting cloud forests in Colombia and Peru. Terrestrial and secretive; rarely observed. Known primarily from specimens and occasional recordings.
