Incredible images capture deer engaged in a rut in Richmond.

Taken by Richmond Park visitor, Carl Myhill, the pictures showcase two stags pushing each other fiercely with their antlers.

In the images female and male deer can also be seen watching on.

Rutting season refers to the annual period of sexual excitement, aggression, and mating behaviour in certain male mammals, such as deer.

The Royal Parks, in charge of Richmond and Bushy Parks, always advise visitors to stay a minimum of 50 metres away from deer.

September to November is known as rutting season (credit: Carl Myhill).

"For your own safety, please keep at least 50 metres away from the deer, and never touch, feed or attempt to photograph them at closer range", said The Royal Parks."
