A herd of elephants on a mammoth trek across China is taking an enforced break -- as they wait for a wayward youngster to catch-up.

The 10-year-old got sidetracked from the family walk several days ago, and is now lagging around 14 kilometres (nine miles) behind.

The elephant herd has travelled around 500 kilometres, and is now lingering a couple of days south of the city of Kunming

Despite repeated calls from increasingly impatient adults, the dawdling dumbo appeared in no hurry.

Chen Mingyong, a professor at Yunnan University who is monitoring the herd's huge hike, told Chinese media that the matriarchs are trumpeting for the youngster to get his skates on.

But state broadcaster CCTV -- which is carrying a 24-hour live feed of the migration -- said he shows no sign of wanting to rejoin the group.

Male elephants usually leave their mother's herd to live alone or in small groups with other males as they reach sexual maturity.

The herd has travelled around 500 kilometres, and is now lingering a couple of days south of Kunming, the provincial capital of Yunnan province.

The migration has captivated Chinese social media and drawn international attention while costing local farmers more than a million dollars in losses.

Wildlife officials at the weekend said they were planning to use "food bait and roadblocks" to guide the elephants to a suitable habitat.

Over 3,500 residents have been evacuated to make way for the elephants, and hundreds of trucks have been deployed to keep them away from densely populated areas, official news agency Xinhua reported.

The wild elephant population in Yunnan stands at around 300, up from 193 in the 1980s, Xinhua said.

Human-elephant conflicts in the region have intensified in recent years due to unfettered development projects that encroach on the animals' natural habitats.
