Size Comparison
Habitat Comparison
นกอินทรีฮาร์ปี
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
นกอินทรีฮาร์ปี
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
นกอินทรีฮาร์ปี
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.
Hawfinch
Europe, North Africa, and western and central Asia. Partially migratory, with northern populations moving south in winter.

About These Birds
นกอินทรีฮาร์ปี
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.
