Size Comparison
Habitat Comparison
Harpy Eagle
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Oriental Stork
Wetlands, flooded rice paddies, rivers, and marshes. Nests on tall trees, utility poles, and artificial platforms.
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.
Oriental Stork
Essentially silent like all storks; produces loud mechanical bill-clattering at the nest as a greeting display. Chicks beg with hissing and squeaking. Rarely vocalizes otherwise.
Geographic Range & Migration
Harpy Eagle
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.
Oriental Stork
Breeds in the Russian Far East and northeastern China. Winters in southeastern China, Japan, and Korea.

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.
Oriental Stork
The oriental stork is one of the most endangered stork species, with fewer than 3,000 individuals remaining in the wild. It was once widespread across East Asia but declined dramatically due to wetland drainage and pesticide use. Reintroduction programs in Japan and Korea have achieved notable success.
