About Ciconia boyciana Swinhoe, 1873
This species, the Oriental stork, is typically larger than the white stork. It measures 100–129 cm (39.5–51 in) in length, 110–150 cm (43–59 in) in height, weighs 2.8–5.9 kg (6.2–13.0 lb), and has a wingspan of 2.22 m (7.3 ft). Unlike the more widespread white stork, the Oriental stork has red skin surrounding its eye, a whitish iris, and a black bill. The two sexes have similar appearance, though the female is slightly smaller than the male. Juvenile Oriental storks are white with orange bills. The Oriental stork is distributed across Japan, China, Korea, and Siberia. It was previously completely extirpated from Japan and the Korean Peninsula. In May 2007, however, a wild hatchling was reported in Japan for the first time in 40 years; this individual was the offspring of two captive-bred storks.
