A female takes refuge up a tree as the males compete for her attentions
The giant panda's courtship and mating sequence - from boisterous beginning to noisy ending - has been filmed in the wild for what may be a TV first.
A BBC Natural History team recorded the magic moments deep in the bamboo forest that lines China's Qinling mountains.
The pictures show a male panda having to fight off the competition as he tries to woo and finally win a female.
The sequence, shot for BBC Two's Wild China series, illustrates behaviour that is rarely displayed in zoos.
With rampaging males on the ground, it can feel safer higher up
These include the loud calls which will make viewers think instantly of the Wookie character from the hit Star Wars movies.
"I liken it to Chewbaccas in a pub brawl," explained Gavin Maxwell, the producer of Wild China.
"Most of the time, pandas live by themselves. It's only in the mating season that they come together; and that's when they start these extraordinary vocalisations.
"The sounds are so unlikely and just the last thing you would expect a panda to make.
"When you get two or three males together with a female there's an awful lot of barking and shouting going on."
Just getting in position to film the pandas took months of research, location reconnaissance and negotiations with the Chinese authorities. Obtaining the filmed sequence itself required an awful lot of patience and skill, and quite a bit of luck.
The Qinling mountains are carved with steep ravines and gullies. The growth of bamboo is so thick it can be extremely hard to get near the pandas, let alone get a clear shot of their behaviour.
If you make too much noise, the creatures will be long gone by the time you find their location.
