We satellite tracked the fall migration of Red-crowned Cranes Grus japonensis, White-naped Cranes G. vipio and Oriental White Storks Ciconia voyciana from the middle part of the Amur River, southern Siberia in 1998 to 2000, and the spring migration of Common Cranes G. grus from western India in 1999 to 2001. In one Red-crowned Crane and two Oriental White Storks, the round trip migration was successfully tracked.
Three of the four successful Red-crowned Cranes migrated down along Bohai Bay to Yancheng north of the mouth of the Yangsu River. They wintered there. The other one migrated down to the mouth of Han River of the Korean Peninsula. In spring, the Yancheng crane took more northern route than in fall, but arrived in the same breeding area as that of the previous year. Ten of the 13 successful Oriental White Storks migrated down through Bohai Bay to Poyang Lake in the middle part of the Yangsu River. The other three wintered along Bohai Bay. All the storks moved little by little, particularly within Russia where extensive natural wetlands are available. In spring, the two storks took more northern route as in the Red-crowned Crane, and one stork arrived in Qiqihar of the Heilonjan Province and the other in Noan of the Jilin Province. Three Common Cranes migrated north through Uzbekistan and Kazakhstan to the southwestern part of Russia.
In some of the staging and wintering areas, the cranes and storks are threatened by serious habitat destruction and chemical pollution.
