Pandas not as solitary as previously believed


Researchers have revealed that Pandas, who are believed to be loners, aren’t actually loners and they spend time with their own.

Researchers electronically stalked five animals in China’s bamboo forests and the data, reported in the Journal of Mammalogy, provides a peek into the secret life of giant pandas and revels how they interact with one another and spend their lives in the wild.

“Pandas are such an elusive species and it is very hard to observe them in wild,” said Vanessa Hull, research associate at Michigan State University (MSU).

For the study, five pandas – three female adults named Pan Pan, Mei Mei and Zhong Zhong, a young female Long Long and a male dubbed Chuan Chuan – were captured, collared and tracked from 2010 to 2012, in the Wolong Nature Reserve in Sichuan.

The researchers found that the pandas hang together sometimes. Three in this group – Chuan Chuan, Mei Mei and Long Long – were found to be in the same part of the forest at the same time for several weeks in the autumn and outside the usual spring mating season.

“We can see it clearly was not just a fluke, we could see they were in the same locations, which we never would have expected for that length of time and at that time of year,” Hull said.

“This might be evidence that pandas are not as solitary as once widely believed,” study co-author Jindong Zhang, postdoctoral researcher at MSU, pointed out.

Chuan Chuan, the male panda, moseyed across a bigger range than any of the females, leading researchers to speculate that he spent time checking in on the surrounding females and advertising his presence with scent marking – rubbing stinky glands against trees.

The researchers also learned about the pandas’ feeding strategy from this surveillance period. Many animals in the wild have a home range, and within that a core area they frequently return to and defend.

“They pretty much sit down and eat their way out of an area, but then need to move on to the next place,” Hull said.

The pandas returned to core areas after being gone for long spans of time — up to six months. It suggests the pandas do remember successful dining experiences, and return in anticipation of regrowth, the researchers noted.
