From Wildlife Extra:
August 2012. Two orphaned wild elephant calves that underwent rehabilitation through the Assam Forest Department and IFAW–WTI run Centre for Wildlife Rehabilitation and Conservation (CWRC) have been seen ‘socialising’ with a wild herd in Manas National Park recently.
“This is the third direct evidence of the rehabilitated elephants with wild herds this year,” said Dr Bhaskar Chaudhury, Regional Head – Northeast, WTI, who leads the project. “This is a good sign and sure-shot evidence that orphaned wild elephant calves that end up in human care can be successfully returned to the wild. They deserve to live a free life in the wild as did their mothers.”
