Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Keel-billed Toucan
Tropical and subtropical lowland rainforests and forest edges from sea level to about 1,900 meters.
Song & Call Comparison
Harpy Eagle
Rarely heard; emits mournful whistled screams 'wheee-oo' and low croaking grunts near the nest. Vocalizations poorly documented given its remote Amazonian habitat.
Keel-billed Toucan
Produces a repeated frog-like croaking 'prrrek-prrrek' or 'terrio-terrio'. Not melodic; the call resembles a mechanical rattle or frog. Also gives bill-clattering.
Geographic Range & Migration

About These Birds
Harpy Eagle
The harpy eagle is among the most powerful raptors in the world, with talons as large as a grizzly bear's claws. It is the national bird of Panama. Deforestation poses the greatest threat to this species, as each breeding pair requires a vast territory of undisturbed forest.
Keel-billed Toucan
The keel-billed toucan is the national bird of Belize and one of the most recognizable birds in the Neotropics. Its oversized bill, which can be a third of its body length, is actually very light due to its hollow honeycomb structure. Toucans roost communally, with up to six adults squeezing into a single tree cavity.
