Size Comparison
Habitat Comparison
Harpy Eagle
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Japanese White-eye
Broadleaf evergreen forests, gardens, parks, and suburban areas. Highly adaptable and common in East Asian gardens.
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.
Japanese White-eye
Sweet, high-pitched 'tsee-tsee-tsee' whistle and soft melodic warbling. Flocks produce a continuous tinkling chorus. Alarm is a sharper 'tset'. Song is gentle and rhythmic.

Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

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.
Japanese White-eye
The Japanese white-eye is a familiar garden bird across East Asia, beloved in Japan where it is called mejiro. These sociable birds form flocks outside the breeding season and are important pollinators of plum and cherry blossoms. Unfortunately, introduced populations in Hawaii have become invasive, competing with native honeycreepers.
