IAR hasn't yet released plans to return Udin to the wild. Since he spent so much of his life in captivity and rehabilitation, he still has a long way to go before returning. Over the past few months, the primary goal has been keeping this frail orangutan alive. If the Instagram post is any indication, the young orangutan seems to be on his way to recovery.
Follow the progress of Udin and all the other orangutans at IAR on Instagram.
