As the spring has come, China’s giant pandas are also entering their mating season. Two pandas have been spotted mating in the wild in Foping Nature Reserve in northwest China’s Shaanxi Province.

The two pandas fell in love with each other after a time and energy-consuming pursuit of the male panda after the female. According to the reserve workers, the female have stayed high up on a tree to “test” the male for ten days since March 26 without eating anything. The male, who seldom walked away, eventually proved his love by persistently waiting for her under the tree.

Finally, the two came to their mating on April 4. The precious process event was recorded by workers in the natural reserve.

According to wildlife experts, pandas have infamously solitary lifestyles -- female pandas only tolerate a male's presence around them two to three days a year during mating season.

Their eggs only live for 36 to 40 hours, making conception even more difficult. The success rate of conception is between 30 percent to 40 percent and no more than 40 percent of cubs survive.
