The Risks of Reintroduction of the Siberian Crane (Leucogeranus leucogeranus (Pallas 1773), Gruidae, Gruiformes)

The reintroduction of Siberian cranes bred in the Oka Crane Breeding Center of Oka State Nature Reserve, Ryazan region, has been underway for 30 years. During this time, 47 eggs were placed in the nests of Eurasian cranes and 190 chicks were released into the wild, including 57 in the pre-migratory staging areas of Eurasian cranes. In order to optimize breeding methods and reduce risks when releasing Siberian crane chicks, it is necessary to take into account the results of work on the reintroduction of Whooping and Red-crowned cranes, as well as to consider the characteristics of the biology of the Eurasian crane.
