Size Comparison
Habitat Comparison
ハクトウワシ
Large bodies of open water including coasts, rivers, and lakes with abundant fish and old-growth trees for nesting.
Oriental Stork
Wetlands, flooded rice paddies, rivers, and marshes. Nests on tall trees, utility poles, and artificial platforms.
Song & Call Comparison
ハクトウワシ
High-pitched, chattering whistle: a rapid 'kleek-kik-ik-ik-ik'. Surprisingly weak and thin for such a large raptor. Also gives a lower 'kwit-kwit' call near the nest.
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
ハクトウワシ
North America from Alaska and Canada through the contiguous United States to northern Mexico.
Oriental Stork
Breeds in the Russian Far East and northeastern China. Winters in southeastern China, Japan, and Korea.

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.
