About These Birds
Black Stork
95–100 cm, wingspan 173–185 cm. Iridescent black with white underparts; red bill and legs. Breeds across temperate Eurasia from Iberia to eastern China; migrates to sub-Saharan Africa and India. Solitary and shy; nests on cliff ledges or large trees. Feeds on fish in clear streams.

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.
