The six cranes, including three males and three females, are around seven months old and were bred in captivity at Nakhon Ratchasima Zoo. They were flown to Vietnam and, following a mandatory quarantine period at the Saigon Zoo and Botanical Gardens, and now are eligible for relocation to Tram Chim for conservation and growth.

The Dong Thap Provincial People’s Committee on December 12 announced the project "Conservation and Development of Sarus Cranes at Tram Chim National Park."

Only 11 sarus cranes, the tallest species of flying birds on earth, have been spotted this year at Tram Chim National Park in Dong Thap province – which used to be the top destination of the bird in the Mekong Delta region.
