My third instalment of the Species in Focus series shifts away from an avian theme and onto one of the UK’s largest residents. While many here associate red deer with the remote Scottish Highlands, some of my most profound encounters have happened right on the doorstep of the capital. In the sprawling, historic expanses of Richmond and Bushy Parks, these ancient giants navigate a unique intersection of wild instinct and urban proximity. In this feature, I’m diving into the lives of London’s largest mammals, exploring how they first came to be a part of life in the capital and how they continue to thrive within the city’s limits.
Red deer are a species that have always been native to Britain, in fact they are one of only two deer species that are truly native to this country. They once roamed the length and breadth of the land but the introduction of Roman agriculture resulted in mass forest clearance, forcing red deer into smaller habitat areas. From that point the deer became a talismanic hunting symbol, reserved for royal and aristocratic parties yet this overzealous practice combined with continued woodland destruction meant that by the 18th century populations of red deer in England and Wales had almost ceased to exist. Even the Scottish population saw its numbers reduced following the Highland Clearances of the late 1700s where many deer-friendly habitats were replaced with sheep farming.
Ironically it was humankind’s love of hunting this species that actually proved to be its salvation. Although its natural woodland habitat had been reduced over time, a number of private deer parks were established, most here in London, that acted as controlled hunting grounds for the country’s elite. The first of these was actually Greenwich Park, where in 1515 King Henry VIII was credited with the introduction red deer for his royal hunts. Henry VIII also established Bushy Park as a royal hunting estate around the same time to serve his nearby residence at Hampton Court Palace.
The largest London-based hunting park was setup in 1625 after King Charles I moved his royal court to Richmond Palace in an attempt to escape the Great Plague. It was initially stocked with 2000 red and fallow deer and, in order to keep the deer in and locals out, Charles I took the controversial step of enclosing Richmond Park with an eight mile long brick wall. This wall is still visible throughout parts of the park today but it’s erection in 1637 was deeply unpopular with the local populace, and is often cited as one of the many grievances that eventually led to his execution.
From there on in the parks were maintained as royal hunting preserves but in 1872, full right of public access to Richmond Park was officially granted by a Parliamentary Act, transforming the space from a royal estate to a public amenity. Most of the deer found in the parks nowadays are relatives of those reintroduced after WWII had depleted stocks. It is believed that Richmond Park is now home to around 650 deer, whilst Bushy Park has a further 350. The herds here are semi-managed but are entirely free-roaming within the park grounds. Overtime the Scottish population has also seen steady improvement in population numbers thanks to land preservation attempts. In fact, it is believed that there are currently an estimated 350,000 red deer in Scotland, a population that has roughly doubled since 1990. Today, the UK has an estimated 400,000 red deer, its highest numbers in over 1,000 years, and there rejuvenated presence is one of the country’s conservation success stories.
Red deer exhibit intriguing social behaviours that fluctuate dependant on the seasons. Outside of the breeding period, red deer typically can be found in single-sex herds. Females, known as hinds, live in stable groups often led by a few dominant females and usually include any offspring, of either sex, from current and previous years. These groups can vary greatly in size, ranging from small family parties to larger herds that can number 50-80 individuals. Males, known as stags, are ostracised from these groups once they reach maturity (1-2 years old) and form loose, less stable ‘bachelor groups’ or live solitarily. Males and females generally live in different areas for most of the year, a behaviour that is witnessed even within the confined Richmond and Bushy Parks.
The one time the groups come together in during the mating season. Known as the rut, this usually occurs at the beginning of Autumn in the UK (often September-October) and produces a period of intense activity. The aim for the stags is to build harems of females with which they can then mate. In order to do this they have to compete with other males to show that they can be the most dominant. This process involves bellowing, a vocal method for advertising their strength to females and to ward off rivals, rolling in mud wallows and covering their antlers in bracken to appear larger as well as more intimidating and fighting. Red deer clashes can result in serious injury as males utilise their large antlers to lock with one another in violent pushing matches.
The rut is one of the most intriguing periods for wildlife enthusiasts and photographers alike but it is also one of the most dangerous. Stags are pumped with testosterone and can act extremely aggressively towards anything that they perceive as a threat; Richmond and Busy Park advise visitors to remain at least 100 metres away from any stags during this time. Successful males will remain with their harem, unless a challenger usurps them, for the mating period, only departing when the season ends and they have mated with as many mature females as possible.
Females have a gestation period that lasts roughly 7.5-8 months, meaning babies are born around late May to mid-June. Hinds almost always give birth to a single offspring, with twins being incredibly rare, with youngsters being referred to as calves. The term ‘fawn’ is often used generically for all baby deer but, for larger species such as the red deer, the term calf is actually used. Red deer calves are born with a reddish-brown coat covered in white spots for camouflage. This spots usually have disappeared after just a few months, after which the youngsters will be fully weaned and independent. They remain with their mother’s herd for at least a full year, staying longer if born female and departing once they hit maturity if male.
Red deer are the UK’s largest land animal and the most impressive part of their physique is the antlers. These antlers are amongst the fastest-growing biological tissue in the world, capable of growing up to 2.5cm per day during peak summer months. At the end of each rutting season, as testosterone levels drop, stags shed their previous years antlers in a process known as casting. New growth begins almost immediately from the permanent bony bumps on the skull called pedicles. Throughout summer the new antlers grow rapidly. They are covered in a soft, fuzzy coating called velvet. This velvet is rich in blood vessels which help supply extra oxygen and nutrients required to stimulate such fast growth.
As the rutting season approaches the stags antlers entering their most formidable stage. The cartilage calcifies into hard bone and the velvet coverage falls away, leaving behind fully formed antlers ready for use in social displays and fighting. Once the rutting season passes the process begins again, repeating each year with the antlers becoming larger and more complex each time. The complexity relates to the number of points (known as tines) that the antlers have, with stags being named in relation to their count: a Royal has 12 tines, an Imperial has 14 and a Monarch has at least 16.
Whilst red deer are entering a general population boom across the country there are a few concerns with the management of herds found here in London. One issue is human-wildlife conflict. Whilst there have been very few recorded incidences of deer injuring humans it is all too common to see visitors repeatedly fleecing the proximity regulations. I have seen people getting dangerously close to deer in Richmond Park, witnessing them attempting to take selfies with, hand-feed and pet these wild animals. The feeding is particularly problematic, and is actually illegal, as it disrupts their natural diet and encourages them to approach humans more regularly.
Given that the deer in London live in confined parks, managing the deer numbers is vitally important to prevent overpopulation and maintain a diverse genetic pool. The red deer have no natural predators in the park and so the process of population management is carried out by the Royal Parks, who conduct regular culls. This practice has proved a point of significant public debate throughout the years; in early 2026 campaigners actually urged a shift towards non-lethal methods like contraception instead of culling.
One of the most intriguing behaviours that I get to witness with the London red deer is their symbiotic relationship with the western jackdaw also found in the park. The interaction between the two species is a classic example of mutualism, where both species derive specific benefits from one another. It is thought the deer benefit as the jackdaws act as a natural form of pest control as it is common to see the jackdaw perched upon the backs and heads of the red deer where they will feed on lice, insects and ticks. In return, during the spring, jackdaw are often seen plucking tufts of fur directly from the deer. This fur is then used by the jackdaw as warm insulation material for their nests but it also helps the deer to shed their heavy winter coats more efficiently. In my experiences, the deer are typically very tolerant of the bird, often remaining content whilst the jackdaws hop all over their bodies.
Having lived in west London for most of my adult life I certainly took seeing these majestic creatures for granted. Taking a weekend stroll through Richmond Park and coming across a herd of females with calves during the summer, watching stags clash antlers during the rutting season or seeing the jackdaw clamber over the deers heads in the spring were all scenarios that simply became a regular part of my photographic adventures. Their large size, impressive features and mythical status make them one of my favourite species to work with and, whilst I am sure seeing them roaming the Scottish Glens is impressive, having such easy access to them here in London is something I’m incredibly grateful for.
Hopefully this article, and my photographic work, has helped you understand how these large mammal came to reside within the capital of Britain or, at the very least, provided you with some new knowledge about a species that you likely observe on a regular basis.
