Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Hawfinch
Deciduous and mixed woodland, orchards, parks, and large gardens with mature fruiting trees.
Song & Call Comparison

Rarely heard; emits mournful whistled screams 'wheee-oo' and low croaking grunts near the nest. Vocalizations poorly documented given its remote Amazonian habitat.
Hawfinch
A sharp, metallic 'tsick' call — the primary vocalization and often all that's heard. Song is a thin, reedy warble. Generally inconspicuous vocally despite its striking appearance.
Geographic Range & Migration

About These Birds
Đại bàng Harpy
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.
Hawfinch
The hawfinch possesses the most powerful bill relative to body size of any European bird, capable of cracking cherry stones that require a force of 27-43 kg. Despite its distinctive appearance, it is famously shy and difficult to observe. The skull contains special adaptations to absorb the enormous forces generated during seed-cracking.
