About These Birds

Black Stork

黑鹳(Ciconia nigra)体长95-100厘米，翼展173-185厘米。具金属光泽的黑色上体和白色腹部；红色喙和腿。在欧亚大陆温带地区繁殖，迁徙至撒哈拉以南非洲越冬。栖息于荒野森林河流，较白鹳更为羞怯。

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.
