EVERYTHING YOU NEED TO KNOW ABOUT THE DEER RUTTING SEASON….
Bushy Park and Richmond Park are home to over 1,000 free roaming red and fallow deer between them and but the rutting season is remains a great mystery to many visitors.
The Royal Parks has put together a simple fact guide to the background of the rutting season which starts at the end of September.
1. During the rut, you may see one stag with up to 40 hinds
The biggest stags will hold harems in the middle of the rut when most of the hinds (female red deer) are in season (oestrus).
The smaller stags will lie in wait to try to mate with the hinds when the dominant stag is in battle or exhausted following a fight.
Being king of the castle comes at a price. The biggest and strongest stags spend most of their time chasing away challengers and preventing hinds from straying, leaving little time for eating or sleeping.
If you would think twice before entering into an enclosed space with a bull, then we urge you to apply this common sense to wild deer, especially during rutting season when stags are flooded with testosterone and adrenaline.
In the run up to the rut, a stag will weigh around 25 stone and have sharp antlers. Being hit by a stag travelling at full speed of up to 30mph is the equivalent of being mown down by a motorbike.
Please remember that deer are wild animals, keep 50 metres away and do not wave food or mobile phones in their faces. We urge all visitors to keep their distance, both for personal safety reasons and to avoid disrupting the natural behaviour of the rut. This photo is an example of what not to do.
In the lead up to the rut, there are a number of physiological changes to male deer including an increase of testosterone, the doubling of neck thickness, the larynx becoming more prominent and the tongue changing shape.
Roars are used as the first line of defence as a way to deter rivals. A deeper louder roar signals a larger animal. The sound of a roar can help rival stags determine from a distance whether to try their luck, and females can use it to judge the best quality males in the area.
If two roars are evenly matched and neither retreats, the animals parallel walk to assess the size and condition of their opponent.
If neither deer backs down, they will lock antlers and engage in a shoving match to settle the dispute.
Stags will thrash about in the vegetation to make themselves look larger. They will also urinate and roll into muddy areas called wallows. This is their equivalent of aftershave on a Friday night!
During the rut you may also notice the male deer tasting the air, this is to determine if the females are ready to mate.
Whatever you do, do not let a dog run in between a stag and his harem. Females come into season for as little as a few hours every 18 or 19 days so a dog’s presence will not be welcomed.
During the rut keep your dog on a lead and under close control. If a stag approaches you let the dog off the lead so it can run away.
If you witness a dog chasing a deer, please call the on-call police officers for Bushy and Richmond Parks on 07920 586 546.
All visitors are reminded not to crowd the deer during the rut. In previous years, we have witnessed dozens of photographers surrounding a single stag. It is not only incredibly dangerous, but it’s also stressful for the deer and can interfere with the course of nature.
As the rut advances, harem-holding stags become more exhausted and there is an increased chance of them being overthrown. A stag barely eats or sleeps during the rut and can lose up to a third of its weight during a fortnight of intense activity. If you see a stag resting on the grass, do not take this as an invitation to go and pet him. Believe us when we say it won’t end well.
Over the years there have been incidents where visitors have suffered injuries from rutting deer that may have been avoided. In 2018, a young girl who was being photographed next to a rutting stag was injured in Bushy Park, and the previous year a visitor was hospitalised after suffering injuries from a male deer in Richmond Park. All incidents almost exclusively happen when people get closer than the recommended 50 metres.
There are slight differences in how the fallow bucks rut. During breeding season, bucks can form a lek – a gathering of males engaging in a competitive display to attract a potential mate. Unlike the red deer who operate harems, it is not uncommon to see a group of 40 does (female fallow deer) with four or five big bucks. In common with other large deer species, during conflict, the buck’s behaviour escalates from groaning and parallel walking to fighting.
Volunteer rangers are on hand in Bushy and Richmond Parks to educate people about the deer rut and why it is important to keep your distance. However, it’s important that people take responsibility for their own safety and remember that deer are wild animals who deserve respect and space.
