She never presented any signs she was pregnant, so we were quite surprised to hear the elephant commotion in the early morning, said Sangduen Lek Chailert, the founder of Save Elephant Foundation. Given the long gestation period of elephants and the lack of fertile bulls at Elephant Nature Park upon SriPrae’s arrival at the park, we are convinced she was already pregnant when we rescued her. We have so many false pregnancies at the park we never suspected she might have been carrying a baby.
