Dry brushland, thorny scrub, and chaco woodland in Bolivia, Paraguay, and northwestern Argentina. Prefers hot semi-arid environments with sparse tree cover and dense ground vegetation.
Great Tinamou
Humid lowland and foothill tropical rainforest from southern Mexico through Central America to Bolivia and southeastern Brazil. Prefers undisturbed forest interior with dense understorey. Nests on the ground.

A low, repeated whistle from dry Chaco scrub. Call is unremarkable — a simple repeated note. Cryptic and secretive; the call is often the only indication of presence.
Great Tinamou
A beautiful, pure whistled phrase repeated at regular intervals from the forest floor. Call is a clear 'wheeeoo-wheeeoo'. Among the most musical tinamou calls in its range.

About These Birds
Brushland Tinamou
A medium-sized plainly colored tinamou with grey-brown plumage and subtle barring. Found in dry brushland and thorny scrub of the Gran Chaco and Pampas regions. Terrestrial and secretive; calls infrequently. Adapted to arid and semi-arid open habitats of central South America.
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.
