A ferocious battle took place in Richmond Park in London. Slide to see the fight between two furious rivals! 

So, who are these vigorous gladiators? 

There are six species of deer in Britain. Based on the spotted fur and the palm-shaped antlers, our fierce wrestlers are fallow deer. The male fallow deer, or buck, can be 1.4-1.6 meters long, 85-95 in shoulder height, weighing 60-100 kilograms. 

During mating season, the bucks spread from the group, and burst into violent clashes from time to time in competitions for females. All bachelors gather in a small areas where the females visit for the sole purpose of finding a mate to breed. Interestingly, the females prefer larger males with bigger antlers and better battle skills, but do not care much about how old the male is. 

Breeding is never an easy task, and winning a fight does not mean the buck can be the winner forever. During mating season, the male fallow deer may even stop feeding to focus on protecting its "wives" from other males. It may lose as much as 17 percent of its body weight.
