The Solitary Nature of Male Wild Boars: Are They True Loners?

In the depths of forests and hidden corners of fields, elderly male boars live a solitary life amidst the social activities and family gatherings of other forest animals. Without any social bonds or familial ties, these boars navigate through life on their own.

This article delves into the daily actions of adult male wild pigs, offering a glimpse into their way of life and the typical behaviors that define their structured, predictable and solitary life.

Typical day of a solitary adult male boar

The old boar starts his morning by foraging for food such as roots, tubers, nuts, berries, and insects in the nearby woods, fields, or farms. After searching for food for a few hours, it usually finds a suitable spot to unwind and bask in the morning sun. Finding a cozy and secluded area to unwind is crucial for conserving energy.

During this period, the wild boar is also involved in behaviors such as making tusk marks on trees, or rubbing against objects to comb its fur and leave scent marks. 

These markers allow communication with other animals nearby, highlighting pig presence and dominance. 

Mud Baths: The Wild Boar's Natural Spa

Like other animals, wild boars typically rest during the hottest part of the day to avoid overheating. During this time, the older male boar often seeks out a shady spot or a patch of mud to cool down.

Resting in the shade helps regulate the boar's body temperature and prevents sunburn on its sensitive skin. Moreover, wallowing in mud serves as an effective way of protection from insects and parasites that may be present in the environment.

The elderly male boar might rest and roll in the mud for a few hours before returning to its daily routine in the cooler temperatures of the afternoon.

After the scorching heat subsides, the boar resumes its search for food, possibly exploring new areas for better options. While foraging, the boar may encounter other solitary boars or small groups of different forest animals, engaging briefly with them through sniffing, snorting, or other vocalizations.

As the sun sets, the wild boar intensifies its search for food, making the most of the fading light before nightfall. When night arrives, it continues to hunt for food, relying on its keen sense of smell and hearing.

Wild Boars in Their Sleep and Their Bed

Wild boars, like all living creatures, require sleep for their well-being. As night descends, boars actively seek out secluded spots where they can unwind and rest.

Despite the common perception of wild boars being dirty, they are careful to avoid defecating close to or inside their resting areas in order to stay clean. 

Wild Boars also meticulously prepare their sleeping beds, often using materials such as spruce branches and dry hay, which help regulate their body temperature during the night. They may cover themselves with soil and pine needles to further shield themselves from insects and parasites.

Wild Boar sleeping spots are strategically chosen, often found near rivers, in wetland forests, or amidst tall grass and shrub areas.

During their slumber, wild boars enter a light, almost half-awake state, maintaining a certain  level of awareness that allows them to quickly respond to any potential threats. During sleep, their sensitive senses of smell and hearing serve as early warning systems, enabling them to quickly detect dangers and take necessary precautions to ensure their safety and survival.

This routine illustrates the typical day-to-day life of a wild boar.

Is an adult boar loner at every stage of life?

Although male wild boars are solitary animals, they do not exist in solitude for the duration of their lives. As small pigs, they live in groups called sounders, typically consisting of females and their offspring. Boars within a sounder work together to protect their young from predators and to find food sources. The dominant female, the sow, leads the group and decides where to forage and rest.

As young males mature, they eventually depart from the sounder to either join bachelor groups or adopt a solitary lifestyle
. This separation from the pack helps mitigate conflicts with the dominant boar and allows them to explore their independence while still relying on their social skills learned within the group to survive the wilderness.

The breeding season is the only time when adult male wild boars encounter other animals of the same kind. The breading season for wild boars usually extends for about six weeks, taking place from November to January. Before this, male boars grow a defensive layer beneath their skin to protect themselves in competitions against other males. During this period, wild boars are utilizing their tusks as well. 

Throughout the mating season, male boars assert their dominance through aggressive actions and physical confrontations, vying fiercely for breeding opportunities. Only the strongest and most capable boar will succeed in reproducing, as competition is fierce. Once dominance is established, the alpha male will mate with several females within his territory.

These intense rivalries often lead to significant injuries, as the males use their sharp tusks in combat. Deep gashes and puncture wounds are common, and the injuries can be severe. 

Following the breeding season, male boars frequently suffer serious injuries and typically lose around 20% of their body weight, often receiving bites on vulnerable body parts during fights with rivals. Despite these hardships, the surviving males have successfully transmitted their genes to the next generation.

Once the mating season concludes, the males shed their protective armor and return to the solitary lifestyle until the next mating season arrives.
