Deer have spots on their body when they are born. These white spots are commonly found on the fawns right after their birth for survival purposes.
However, a couple of deer species such as moose and reindeer doesn’t have spots when they are born. So, most deer species are born with spots.
They lose their spots in the fall when summer coat is shed and they get a winter coat. They are about 6 months old when it happens.
Between spring and summer, deer fawns are born. After 10 months of gestation, they finally arrive with a cute face alongside a reddish-brown body. Also, they have around 300 spots all over their body. These spots cover the topmost coat of the fur in varying forms and sizes.
As fawns, almost every deer species have white spots all over their body with a special purpose. The spots serve as camouflage in the wild and prevent them from predators. However, the speckles tend to disappear when the first coat is shed. But three species keep these spots throughout adulthood: the sika, chital, and fallow.
Fawns need the spots to survive when they are born. But when they gain maturity, independence, and strength the spots disappear completely. It takes about 120 days. By early fall, when the fawns would be around 6 months, the first fur shed occurs and they lose all the spots.
While food is available in the wild most of the time, if they smell something different, they jump fences in search of the food. Besides, deer experience an intense flow of energy during mating season. They will do whatever it takes when they locate the opposite sex, includes jumping fences.
Do deer change colors?
The fur coat of deer tends to change color and it depends on a specific time of the year. Hence, when you find a deer during the spring, it will have a reddish color. And, when you see them during fall, their fur appears brown.
In general, a deer’s coat is specifically designed to serve two important purposes: first as camouflage and second as thermoregulation. During the summer season, the coat becomes reddish and thin. As such, it allows the animal to cope with excessive heat. The process of molting starts during the fall.
It is a kind of hormonal change that gets triggered by the changing seasons. As a result, the reddish coat turns into brown or faded gray while the new coat for the winter season tends to grow. Furthermore, this new coat comprises two different layers.
The hairs present on the outer guard are stiff and hollow. And, it grows 2 inches longer compared to the undercoat. The coat color tends to become lighter in agricultural surroundings where the animal is exposed to direct light whereas darker in forested areas. And, these changes occur irrespective of the seasons.
