THE SOUND
Roars and groans
Red deer stags roar and grunt during the rut; fallow bucks groan loudly. The rut runs from the end of September to November for red deer.

fight last.
Every autumn, Britain's parks and hillsides fill with the sound of deer competing to breed.

The rut is when male deer contest for females. It looks like a brawl, but deer experts describe a ladder of displays, from roaring to walking side by side, that usually settles things before antlers ever touch. This independent guide explains what to look for, and how to watch without getting too close.

THE SHORT ANSWER
A contest,
mostly for show.
The British Deer Society describes behaviour that escalates step by step.
Most rivals are sorted out long before a real fight.
SIZING UP
The parallel walk
Rivals walk side by side, bellowing challenges. The British Deer Society says serious fights happen mainly between stags of similar size that cannot settle dominance any other way.

WATCHING
Stay 50 metres back
The Royal Parks asks visitors to keep at least 50 metres from deer, and up to 100 metres if they are active, and to bring binoculars for a closer look.

TWO NUMBERS WORTH KNOWING
Why the distance
matters.
One number from the Royal Parks' rules,
one on what a rutting stag can do.
50 m
Minimum distance from deer
Keep at least 50 metres away, and up to 100 metres if the deer are active. The more space the better during the rut; bring binoculars if you want a better view.
SAFE DISTANCE · THE ROYAL PARKS
30 mph
Top speed of a rutting stag
The Royal Parks says rutting stags can weigh over 25 stone and reach up to 30 miles per hour, which makes them dangerous if disturbed.
SPEED · THE ROYAL PARKS
The National Trust says stags build up weight in August and September, then may not eat for a month during the October rut as they put their energy into competing.
FOUR HABITS FOR WATCHING
Enjoy the rut,
from a distance.
These come from the Royal Parks' safety advice for Richmond Park and Bushy Park, and apply in any deer park.
Keep 50 metres back
Up to 100 metres if the deer are active. Use binoculars or a long lens instead of walking closer.
Leave dogs at home or on a lead
Loose dogs can approach and provoke deer. The National Trust suggests leaving your dog at home when watching the rut.
Never get between two deer
Do not intervene between rutting deer or join a crowd surrounding them; a crowd makes deer nervous.
Back away calmly
If a deer approaches or seems threatening, back away slowly. Don't run, shout or wave your arms, as sudden movement can provoke it.
WHERE TO HEAR IT
An old
autumn show.
The National Trust lists places such as Petworth in West Sussex, home to between 700 and 800 deer and a herd for over 500 years, and the medieval deer park at Studley Royal in North Yorkshire. JMW Turner even painted fighting bucks at Petworth.
Red deer are Britain's largest land mammal: stags weigh 90 to 190 kg. Their antlers are cast in March or April and regrow, clear of velvet, by August or September, just in time for the rut.
