These mammals caught people’s attention after they were spotted roaming at residential areas in Yuxi city, Yunnan province, in late May. After a short rest, they moved on again and entered Yuanjiang county of Yuxi city on April 16. Four days later, a male elephant left the herd and began to wander around the cities alone. The mammals left the nature reserve and headed some 100km down south. Due to a series of wildlife protection measures, the number of wild elephants in Xishuangbanna National Nature Reserve has double-up over the past four decades.
