- Аннотация: The article describes and shows maps of migration routes in 2021 and 2022 of two young Red-crowned Craned raised in Muraviovka Park captive breeding facilities by their parents and released into the wild. It may be useful to try releasing one-year-old Red-crowned Cranes raised in captivity into groups of birds feeding in crop fields in spring during the first few days after their arrival from the winter grounds. Such groups usually include young non-breeders and adult birds who have lost their partners. Another interesting option would be to test releasing captive-raised cranes into pre-migratory flocks in the fall.
