Under a footbridge in southwest China's Yunnan province, a lone female elephant makes a rare appearance at a clearing on the edge of thick forest, ignoring the heavy rain and the gathering crowds to graze and bathe in the chocolate-colored water.

Usually, visitors hoping to spot the animals should wait until February or March, when the females are seeking mates, said Qin Ganglin, a protection officer at the Wild Elephant Valley in Yunnan's Xishuangbanna region, on the border with Laos and Myanmar.

"They don't come out very often right now, and only sporadically," he said.
