Photographer Mark Bridger, 45, took the autumnal images over the last two weeks at the famous park in south west London.
The area, often called the Old Deer Park, is 147 hectares in size and is home to around 650 animals - 300 of which are red deer and 350 are of the fallow species.
October and early November are traditionally the months when stags lock antlers to compete for mating rights with the females - an act that has been captured in these stunning photographs, taken at the largest of London's Royal Parks.
Arriving at dawn, Mr Bridger caught some of the action on camera - watching a pair of fallow deer fight for over an hour.
In the background a herd of females can be seen watching the fight like a ringside boxing crowd to see which male will come out on top.

Its body tenses as it waits eagerly for someone - perhaps a loved one - to return home.
This adorable photo is among more than 1,500 images to have captured the 'essence' of felines - including their wilder, more mischievous side.

The photos, submitted by owners as part of an international competition, aim to highlight the need for feline welfare across the world.
In one photo, a cat yawns in front of a pale green background - showing off its fanged teeth and curled-up tongue.
The animal's eyes are creased and its ears tensed as it prepares to turn in for the night. In another, a grey cat licks its lips with a bright pink tongue - while staring into the camera with piercing yellow eyes.

And another is making the most of the sun - its ginger fur ablaze as it stands in the middle of a field.

The 'Purrfect Pictures' competition, launched by feline charity International Cat Care, attracted more than 1,500 submissions from both amateur and professional photographers around the world.
Categories included 'Close-up cats', 'The cat-human bond’, ‘Cats in action’ and ‘The wild side of cats’ - with entries judged by the charity’s chief executive, as well as Digital Photographer and Your Cat magazine.
Phil Croucher, from Norwich, was crowned overall winner for his 'watching and waiting' photo of a cat gazing out of an open window pane.
The amateur photographer, 47, also won the 'Cats in action' category for his three successive shots of the inquisitive animal - taken from outside the window.

International Cat Care chief executive Claire Bessant said: 'We were looking for photographs which speak 1,000 words on behalf of cats, communicating their beauty, unique nature and bond with humans, and therefore why it’s important to ensure they are looked after properly.

It is said the beauty of nature is best reflected in art, but as these pictures show, sometimes nature needs no help in reflecting itself.
The stunning symmetrical images capture the serene elegance of the natural world as if a giant mirror has been placed across the wilderness.
Photographer Mark Brodkin, 45, racked up months of research and spent hours at the locations in his quest for the perfectly symmetrical shot.
The intrepid snapper, from Toronto, Canada, said: 'I travel all over the world to photograph the most beautiful landscapes I can find.

'In my pursuit of incredible scenery I ventured to these locations. I spend months researching a location before I arrive using the internet extensively and other photo books to gain inspiration and information.
'Once I arrive in a location I typically scout the shooting area when the light is not great and then return for sunrise or sunset to shoot.
'Most of the time it takes several trips to the same location to get the image that I am seeking.' The breathtaking scenes were taken at beauty spots across Canada and America, including Sparks Lake in Oregon, America.
Mr Brodkin uses trial and error to find the right composition and the perfect moment for each photograph he takes.
He added: 'It takes a great deal of patience, persistence and determination.

Peck Lake in Algonquin Park, Northeast Canada: Mr Brodkin uses trial and error to find the right composition and the perfect moment for each photograph he takes, sometimes traveling back and forth to locations over a period of months
'These locations may only look this way for a few minutes - these are the minutes that I try to shoot.
'In some instances, I can drive my car right up to the shooting location and get the shot instantly.
'In other cases getting to the location can require extremely long hikes and camping overnight.
'Once I am in the location, I can spend several hours shooting, but the best images often some from the shots taken around sunrise or sunset.
'When the lighting is working and the location is right, you can really feel it.
'I know in my heart that I am capturing something beautiful.
'I also know that the light and colour will only last a short time, sometimes it is a matter of seconds.
'My adrenaline is rushing when I know there is an opportunity to get that 'winner' shot.'

Sparks Lake in Oregon: Mr Brodkin is by day a partner at a private equity firm and has been travelling the world since 2009 to capture some of the world's most picturesque spots
His favourite photograph, Pristine Bells, was captured at Maroon Bells in Aspen, Colorado, US, last month.
But it nearly proved his most difficult photograph yet.
He said: 'For months I looked forward to travelling to this location in October to shoot the beautiful Maroon Bells while the leaves were full of yellow.
'Days before my scheduled flight, I learned that the US government would be shut down and the road there was closed to vehicles.
'Discouraged, but still determined, I devised a back-up plan.
'In order to get to the location, I would take a mountain bike on a 12 mile return trip.
'The challenge was that it was eight degrees and snowing and I needed to make the trip alone in the dark at 3.30am.
'Still groggy from my flight in and a little scared, I hit the road and started the long ride to the bells.
'But when I arrived at sunrise I was treated to the most incredible view.
'I call this image 'Pristine Bells' and it is my favourite.'
Mr Brodkin is a partner at a private equity firm and has been travelling the world since 2009 to capture some of the world's most picturesque spots.
He added: 'There is so much that can go wrong with a mirrored landscape.
'Too many clouds, too few clouds or the slightest amount of wind can all ruin the image.
'So often I leave the location without a photograph, but when it all comes together it is incredible.'
