History of Red-crowned Crane Grus japonensis and its habitats in China

Abstract

The historical distribution of the Red-crowned Crane Grus japonensis together with changes in its breeding and wintering grounds in China are reviewed. According to historical information the bird mainly bred in Heilongjiang and Jilin Provinces and wintered at coastal regions near the Yangtze estuary. Due to geographical and anthropological changes, the breeding grounds gradually moved to the west and south while the wintering grounds moved northward. Efforts have been made to protect this endangered species but factors still exist which restrict further development of the population.
