About These Birds
Thicket Tinamou
A medium-sized tinamou with rich cinnamon-brown plumage, barred wings, and a pale throat. Widespread in dry forest and thickets from Mexico to northern Colombia. Commonly heard calling with a repeated whistle in second-growth scrub and dry forest. Adapts well to degraded habitats.
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.
