1. There are 60 deer species.

Deer are highly diverse animals, with over 60 species of deer worldwide. They inhabit various ecosystems across the globe. 

In North America, the white-tailed deer is the most common deer species, mainly found in forests, grasslands, and even suburban areas. Despite their name, the white-tailed deer sport reddish-brown coats in summer and grayish-brown ones in winter. On the other side of the continent, the Barbary red deer is the only species native to Africa.

Moving westward, we can find the mule deer in western North America's rocky mountains and arid landscapes. Named for their large, mule-like ears, they rely on their exceptional hearing to detect predators lurking nearby. 

As we venture into the Arctic regions, we encounter reindeer, also known as caribou, who display remarkable resilience in their harsh environment. Their furry coat provides excellent insulation, while their large, concave hooves allow them to dig through the snow for sustenance.

The largest species of deer was the Irish giant deer, which is 7ft tall. Today, Moose is the largest species (weighing up to 700 kg and measuring 6 ft long). Consequently, the smallest deer species is the Pudu, which grows up to a foot and lives in South America. Reindeer are the only domesticated species of deer.

2. Deers have many names.

Next on our deer facts list: Deer have various names. For example, stags, harts, and bucks are just a few terms that distinguish deer by age, sex, and species.

Stag is a general term that refers to an adult male deer. In contrast, harts refer to adult male red deer and Sika deer. Meanwhile, the adult males of white-tailed, black-tailed, and mule deer are called bucks. 

Like their male counterparts, female deer also have several names. A female deer in most species, like the European roe and Chinese water deer, is a doe. Meanwhile, female deer in larger species are hinds. A female moose, elk (Wapiti), or caribou3 is known as a cow.

3. Baby deer are called fawns.

A mother deer usually births one baby deer during spring and early summer. These baby deer, or fawns, sport a coat adorned with spots, typically white or light, which they use for camouflage. Their light coat conceals the vulnerable fawns from their natural predators as they hide in tall grass or dense underbrush during their first weeks of life4

As the young deer grows and develops adult coloration, these spots gradually fade, usually disappearing when they reach 3 to 4 months old. Remarkably, fawns possess the incredible ability to stand and walk within hours after birth. 

Impressively, fawns can run for up to 30 miles per hour. Their agility, speed, and effective camouflage significantly increase their chances of survival during those vulnerable first months of life.

4. They are masters of disguise.

Another deer fact is that deer can blend into their surroundings through adaptive coat patterns. These patterns, unique to each species, undergo seasonal changes. During the warm months, their coats take on a reddish-brown hue, blending seamlessly with lush vegetation and undergrowth. 

In contrast, deer coats turn greyish-brown when temperatures drop and the leaves fall. This change in coat provides better insulation and improves their disguise against decaying foliage and bare trees.

Different deer species also have unique coat patterns. For example, the fallow deer's coat features distinct spots. These spots become more pronounced in the summer months and fade in winter. Similarly, the Sika deer's coat showcases white spots arranged in neat rows. This pattern helps break up their silhouette when hiding among tall grasses and underbrush. 

These intricate designs, combined with variations in color and texture, serve a dual purpose for deer. They help them evade predators like mountain lions, regulate body temperature, and protect their skin from harmful ultraviolet rays. 

5. A male deer grows and sheds its antlers every year.

Another interesting fact about deer is that only male deer grow antlers. Furthermore, most deer species shed them annually2. However, not all stags have antlers. The Chinese Water Deer are the only deer species that don't grow antlers. 

Deers grow and shed their antlers for a variety of reasons. Male deers use their antlers during mating season (also called rut). When rut approaches, bucks engage in fierce battles, using their deer antlers to establish dominance and compete for the right to mate with does. 

These dramatic antler clashes, known as "rattling," echo throughout the forest as bucks lock their antlers together in intense power struggles5.

Interestingly, once the breeding season ends, deer shed their former weapons. Decaying antlers return essential nutrients to the ecosystem, paving the way for a new, potentially larger set of antlers to grow the following year.

6. Some species grow fangs instead of antlers.

You read it right. There are actual vampire deer; species like the Siberian musk deer and Chinese water deer sport vampire-like fangs instead of antlers. Just like antlers, they use their fangs during the mating season. Males use their fangs to fight each other and attract mates.

7. They are herbivores.

As most people know, deer eat grasses, mushrooms, leaves, fruits, and even bark. A deer's sense of smell allows an opportunistic nature, and they take full advantage of the food available in their habitat, which varies across seasons. 

Deers feed on leafy green plants, tender grasses, and newly sprouted leaves upon the arrival of spring. Then, as summer rolls in, their diet expands to encompass a more diverse array of plant materials, such as flowers, fruits, and seeds.

Autumn ushers in a change in deer's dietary focus as they seek out high-energy foods like acorns and nuts to sustain them through the harsh winter months. Once winter arrives and food sources become scarce, deer turn to woody vegetation, including twigs and bark of young trees, to stay nourished.

8. Deer are excellent swimmers.

These fascinating woodland creatures showcase astonishing swimming abilities that often go unnoticed. Their streamlined bodies, elongated limbs, and flexible joints give them a swift and agile movement in the water. 

Their water-resistant fur, coupled with air-filled hollow hair, contributes to buoyancy, reduces drag, and aids in maintaining balance while swimming. Furthermore, their strong legs and specialized hooves, equipped with an interdigital membrane, generate significant propulsive force and allow efficient swimming strokes.

However, deers don't swim for fun. One primary use of their swimming abilities is for foraging. Deers often venture into wetland areas and shallow water bodies to access aquatic vegetation, an essential part of their diet.

Swimming also plays a crucial role in deer survival strategies, particularly during migration and dispersal. In their quest for food, mates, or new territories, deer may encounter rivers, streams, or other bodies of water that obstruct their path. 

Additionally, swimming serves as a defense mechanism for deer, allowing them to escape predators. When faced with danger, deer can swiftly enter bodies of water and swim safely, leaving their pursuers behind.

9. Deers “pronk” as a means to communicate. 

Deer exhibit various unusual behaviors, setting them apart from other wild animals. One such behavior is known as "pronking" or "stotting." This action involves a series of high, stiff-legged jumps. An average deer can jump as high as 10 ft.

Pronking is a warning signal, alerting other deer in the herd to potential threats. This behavior helps deer communicate with one another and maintain group safety. Additionally, pronking is an evasive tactic, making it difficult for predators to keep up with the deer's sudden bursts of height and speed.

Contrary to what one might think, pronking isn't just a panic response or an alarm signal; it also helps deer communicate within the herd. Some researchers suggest that stotting may showcase a deer's physical fitness and agility, signaling to potential mates that they are strong and capable. 

In this context, pronking becomes a way for deer to assert themselves and demonstrate their suitability as partners.

10. They freeze when threatened or startled.

Startling a deer can trigger a series of fascinating, instinctive behaviors. One of the primary responses to danger is the "freeze" response. When they sense a potential threat, deer freeze or stand motionless1

Many wild animals deploy this tactic, like the infamous opossum. By freezing, deer prevent predators from detecting them. As they stand frozen, deer raise their ears and use their keen sense of hearing to assess the situation further, deciding if it's necessary to flee.

In addition to freezing, deer have developed another instinctive behavior to alert their peers about potential danger: "flagging." When sensing danger, for example, a male white-tailed deer raises its tail to expose the bright white underside. 

Other deer species nearby can see this visual cue from far away, prompting them to pay close attention to their surroundings. Flagging is particularly useful in forested environments, tall grasses, or areas with limited visibility. Once the other deer acknowledge the warning, they each decide whether to adopt a freeze response or initiate an escape.

11. They are social butterflies.

These stunning creatures observe social structure. Deer groups, called herds, form hierarchies typically based on age and size, ranging from a few individuals to several dozen members. The composition varies due to the time of year and the specific deer species. 

Within the herd, both males and females establish their positions in the pecking order, including the role of the dominant male leader. In species like the White-Tailed Deer, the largest males hold the highest rank, with adult females following closely. Subordinate to all others are the yearlings and fawns. These hierarchies are crucial in determining access to food, mainly with limited availability.

Deer use body postures, vocalizations, and, for males, antler sparring to display dominance or submission. This hierarchy allows deer to maintain order, offers protection, and grants access to resources.

For example, group vigilance against predators keeps all members aware of potential threats. A male herd can watch over female herds for protection. Sharing knowledge about food sources and shelter also allows the pack to thrive in their environment. 

Like humans, deer maintain their social bonds through physical contact, grooming, and vocalizations, fostering a sense of unity and camaraderie among the animals.

12. Some species are endangered.

The conservation status of deer varies within the different species. Adaptable species like whitetail deer and mule deer flourish across various habitats, boasting stable or increasing populations. Yet, not all deer are so fortunate. 

Among the critically endangered species of deer are the Bawean deer, Calamian deer, Philippine spotted deer, Key deer–the smallest in the North American deer family–and Père David's deer. Diseases, habitat loss, climate change, entrapment, and hunting are the leading causes of their decline. 

The Irish elk, the largest deer species, went extinct because of climate change 12,000 years ago. Moreover, illegal and unregulated deer hunting continues to pose a danger. For instance, hunters in Kazakhstan hunt deer like the roe deer for their venison, a staple food.

Besides, hunters kill deer for their hide and antlers. Likewise, other countries consider deer hunting a sport. These activities are why sustainable hunting practices play a crucial role in deer conservation. Enforcing hunting regulations and educating the public on responsible practices can help safeguard deer populations from overexploitation. 

For example, promoting non-lead ammunition reduces the risk of lead poisoning in deer and other wildlife. On the other hand, more targeted interventions are necessary for already threatened or endangered deer species. Meanwhile, captive breeding programs and reintroducing individuals back into their natural habitats ensure the survival of these iconic animals.
