Habitat Comparison
Dwarf Tinamou
Intact campo sujo and campo limpo grasslands of the cerrado in central Brazil. Extremely sensitive to burning, grazing, and conversion of native grasslands. One of the world's most poorly known birds.
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.
Song & Call Comparison
Dwarf Tinamou
Poorly documented; the Dwarf Tinamou is an endangered cerrado endemic whose call is a thin, very high-pitched whistle. Rarely recorded; secretive in tall grass.
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.
Geographic Range & Migration
Dwarf Tinamou
Found in the coastal Humboldt Current region of Peru and Chile. Largely sedentary; range closely tied to cold upwelling waters.

About These Birds
Dwarf Tinamou
The smallest tinamou in the world, weighing only 40–50 g, with brown-streaked plumage and a very short bill. Critically Endangered and poorly known; restricted to intact cerrado grasslands of central Brazil. Considered one of South America's rarest and most enigmatic 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.
