Roe Deer

Let's look at the definition of Roe deer. The roe deer (genus Capreolus), also known as the roebuck, is a small, graceful Eurasian deer in the Cervidae family (order Artiodactyla). The two species of roe deer are the European, or western, roe deer (Capreolus capreolus), and the larger Siberian roe deer (Capreolus sibiricus) (C. pygargus). Despite the fact that they are found in the Old World, roe deer are more closely related to New World deer than to Old World deer. They thrive in cold environments and can be found from northern Europe and Asia to the high mountains of Central Asia and south to Spain.

In the summer, the roe deer's coat is reddish-brown, and in the winter, it is greyish brown with a prominent white rump patch. The male has short, three-tined antlers that are roughened and expanded at the base, presumably to shield the skull from antler punctures. The European roe deer is a nearly tailless deer, standing 66–86 cm (26–34 inches) at the shoulder and rarely weighing more than 30 kg (66 pounds). Siberian roebucks weigh around 50 kg (110 pounds).

Roe deer have adapted to life on the woodland edge. They are experts at capitalising on the natural opportunities presented by wildfires and floods. They also benefit from human landscape disruptions and flourish when given some attention and maintenance. They are popular game animals, and their venison is coveted. Roe deer are quick runners and adept thicket hiders. The roe deer barks when it is startled.

Roe deer have a unique reproductive biology that relies on the summer vegetation pulse to directly compensate for the high cost of rutting. Other northern deer, such as the red deer, use the summer vegetation to store fat, which is then used up during the rutting season in the fall. The roe buck, on the other hand, foregoes expensive fattening, establishes a territory that overlaps the ranges of two or more females, and breeds in late July or early August. However, for such a small-bodied deer, this presents a problem because little deer have short gestation periods. If gestation began immediately after mating, fawns would be born 150 days later, in December, in the dead of winter.

Fawns must be born in late May, just after spring foliage begins to develop, in order for them to survive and for females to sustain breastfeeding. The roe deer addresses this difficulty by using delayed implantation, in which the fertilised egg, after becoming a blastocyst, stays dormant in the uterus until the end of January. The egg implants in the uterus and grows into a fawn, which is born 276–295 days after mating, in late May to early June.

Roe Deer Characteristics

Physical Description

Size: They stand 60–75 cm (2.1–2.5 ft) tall at the shoulders and have a body length of 95–135 cm (3.1–4.4 ft).

Weight: They can weigh anything from 15 and 35 kg (33 and 77 lb) depending on size, thanks to a light body and a tiny skull (head).

Fur: Adults have a reddish-brown coat in the summer that becomes grey, light brown, or even black in the winter. They feature a distinctive black moustache stripe and a white chin.

Tail: The tail of a roe deer is so short that it is frequently misidentified as tailless.

Antlers (Horns): In excellent conditions, healthy males can grow antlers up to 20–25 cm (8–10 in) long, with two, three, or even four points.

Sexual Dimorphism: Except for the fact that females have heart-shaped rump patches and males have kidney-shaped rump patches, there aren't many apparent distinctions between the sexes.

History, Distribution & Habitat

The roe deer, along with the red deer, is one of the two really native deer of the British Isles. They have been documented from before the Mesolithic period (6000 to 10000 years BC).

Roe deer are now common throughout the British Isles. They are highly linked with woods and have risen in both number and distribution as woodland planting grew in the twentieth century and strategic reintroductions occurred in Victorian times. Previously, roe deer had a near-catastrophic decrease as a result of overhunting and deforestation. Northern Ireland is devoid of roe deer.

Roe deer are mainly connected with woodland and forest borders. They may also be found in places with copses, brush, and hedgerows, as well as agricultural fields. As they take advantage of more urban environments, they are progressively infiltrating regions closer to our towns and cities.

In the countryside, roe deer are frequently viewed as both a good and harmful impact. They can cause harm to young woods and agricultural crops through browsing, yet many landowners and rural enterprises rely on roe deer hunting and venison sales to augment their revenue. It is now critical to strike a balance between the demands of a healthy roe deer population and the needs of the environment.

Breeding, Behaviour and Lifecycle

The mating season, or rut, lasts from mid-July until mid-August. Prior to the rut, bucks become aggressive and establish exclusive territories around one or more does. Fights between bucks can result in significant injury or death, with the winner claiming the loser's territory or accompanying doe. Courtship entails pursuing the buck and doe for a period of time until the doe is ready to mate.

Despite the fact that mating happens at this time, the fertilised egg does not implant and develop until January. It is considered that this is an adaptation to avoid giving birth during the harsh northern winters.

The gestation period is nine months (four months of no embryonic growth followed by five months of foetal growth), and children (typically two or three) are born between May and June. During the first winter and immediately after delivery, there may be a high rate of death.

Roe does not have exclusive territories but instead lives in overlapping home ranges. Males have been observed mating with several females, while females have been observed mating with many males.

Roe deer are solitary animals that may congregate in small groups during the winter. They are active 24 hours a day but prefer open places during the hours of the night in communities that experience frequent disturbance. The busiest times of day are at dawn and dusk.

When frightened or disturbed, both sexes of roe deer produce dog-like barking noises. During the mating season, a high-pitched piping cry is used to attract bucks. During courting, bucks make a rasping sound. When young roe deer become separated from their moms, they produce a high-pitched whistle to attract their mothers.

Behavioural Characteristics

(image will be uploaded soon)

During the summer, male roe deer tend to be alone, roaming around by themselves. Females with newborn pups, on the other hand, dwell in groups, especially during this season. During the winter, virtually everyone lives in family groupings.

These ensembles' compositions vary greatly. A group in a woodland biotope can have between 40 and 90 members, but in an open biotope, it can have as few as 10-15. When they are surprised, scared, or threatened, they make a dog-like barking sound or cry, flashing out their white rump patch, and then leaping away at speeds of up to 60 kmph (37 mph).

The males are aggressive. They get into battles every year during mating season. Typically, the rivalry takes place between an adult male from one territory and a younger man from a nearby area. Such brawls can result in catastrophic injuries and even death.

Conservation Status of Roe Animal

Status of Conservation Since prehistoric times, roe deer have been hunted. During the 18th century, they became extinct in England, Wales, and southern Scotland, and populations were reintroduced to southern England (Dorset) and East Anglia in the 19th century. As they became more common, they were labelled "vermin" because of the harm they caused to forestry, agriculture, and horticulture, and their numbers have been reduced as a result.

Roe deer populations may currently number as many as 500,000 and are growing. Since the 1970s, there has been a surge in interest in roe as a game species and for meat. As a result, they are currently governed by a number of Acts of Parliament that impose close seasons.

Mating Habits of Roe Animal

Roe animals are polygynous, with a single male mating with many females. When males chase females during courting, they flatten the underbrush, forming a figure-eight configuration known as a "roe ring." During courting, males may use their antlers to push fallen leaves and dirt about. The breeding season lasts from July through August. Gestation lasts 10 months, and two-spotted children of the opposite gender are generally born. 

The youngsters hide in the tall grass until they are ready to join the herd. They are suckled many times a day for around three months. Roe animal adults frequently abandon their children if they smell or sense the presence of another animal, especially a human.

Population Threats

In continental Europe, up to 90% of these deer perish before reaching the age of one year, falling prey to foxes and lynx. Many fatalities are also caused by respiratory diseases and malnutrition. The tiny population that remains in Syria is seriously threatened by habitat loss and human persecution.

Population Number

The IUCN Red List and other sources do not offer a total population size for Roe deer. According to the IUCN Red List, the population of this species in central Europe is estimated to be approximately 15 million individuals. Roe deer are now categorised as Least Concern (LC) on the IUCN Red List, and their numbers are growing.

Ecological Niche

The Roe animal is valuable as a game animal. Because of this, as well as their vast and plentiful distribution, they are attractive for scientific research.

Roe Deer Endangered

The Roe deer is another species on the endangered deer list (Capreolus capreolus). It mostly inhabits several European nations, although it is also found in northern Iran and Iraq. In terms of subspecies, the European roe deer and the Siberian roe deer are the two varieties of Roe deer included on the endangered deer list.

It's worth noting that various deer species have varied coats depending on the season. They have a greyish brown coat in the winter and a reddish-brown coat in the summer. In addition, unlike other deer species that have bigger antlers, the roebuck has tiny antlers that are larger at the base and have a unique three-tined form.

It has a short tail and prefers to live along the forest's edge for safety. The good news is that, despite being listed as an endangered deer species, it is an adaptable species that can survive with minimal maintenance.

During the winter, deer consume heather, ferns, and acorns, while in the summer, they eat ash, wild rose, and bramble.

Did you know?

• A male roe deer is referred to as a 'buck,' while a female is referred to as a 'doe.' Mating takes place in July and August, but females postpone implantation of the fertilised egg until January of the following year, ensuring that the young are not born during the hard winter months. In May or June, two or three white-spotted children are born.

• Except for Scotland, the roe deer went extinct in the UK during the 18th century, following which it was reintroduced to the rest of the nation during the 19th century.

• The roe deer is the only hoofed mammal in the world with ‘delayed implantation' (i.e., the fertilised eggs beginning to develop only in winter).
