Roe deer (Capreolus capreolus) is a species of small deer native to Europe, Western Asia, and parts of Africa. Roe deer are small to medium-sized deer, typically weighing between 15 and 30 kilograms. They have short, reddish-brown fur in the summer and grayish-brown fur in the winter.

Roe deer have white spots on their backs and rumps, and a distinctive black nose and white chin.

The roe deer has a distinct white patch on its rump, which covers almost the whole of the roe deer's rump and looks like a not-so-regular heart.

This feature makes the roe deer look more cute, but it is not an ornament.

Scientists believe that the white patches are one of the means used by these animals to confuse predators.

This is done by constantly jumping and running to make the white patches shiny, making it difficult for predators to target them. This research was published in Behavioral Ecology and Sociobiology.

On the other hand, female elk will often cock their tails when carrying their cubs, allowing them to follow them.

The inner side of the tail of the young muntjac was also large and white and very obvious when cocked.

In a forest environment with poor vision, such a visual signal is as obvious as a beacon.

Roe deer are found in a variety of habitats, including forests, woodlands, agricultural fields, and scrubland.

They prefer areas with dense undergrowth and cover and access to water sources.

Roe deer are herbivores and primarily eat grasses, leaves, buds, and shoots. They may also eat fruits and nuts when available.

Roe deer are generally solitary animals, although they may form small groups during winter.

They are most active during dawn and dusk, and spend the hottest parts of the day resting in shaded areas.

Roe deer breed in the summer and females typically give birth to one or two fawns in the spring.

Roe deer reproduction is delayed by 4-5 months, which is an uncommon reproduction pattern in the animal kingdom, hence the name "embryonic delay".

The mating time of roe deer is usually in July, and the cold climate and food shortage in winter do not provide enough nutrients for the female roe deer to maintain the growth and development of the embryo.

Therefore, female roe deer will take control of embryonic development stagnation to reserve nutrients.

They play a key role in the ecosystem as herbivores and prey animals and are a popular subject for wildlife enthusiasts and photographers.
