About These Birds
Small-billed Tinamou
A small tinamou with brown plumage, pale underparts, and a notably short fine bill. Widespread in cerrado, savanna woodlands, and forest edges of central South America. Often calls from dense grass or low scrub. One of the few tinamous adapted to open and semi-open 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.
