Deer are found in Europe, Asia, North Africa, North America, South America, Australia, New Zealand, and New Guinea. They mostly live in the forests. You can also find them in the Mountains. In North America, deer live all the way up in the Canadian Rockies.
Male deer are know as Bucks and grow antlers. Female deer are know as Does and do not grow antlers though both genders of Caribou grow antlers ( Caribou are in the deer family ). A Doe gives birth to 1 or sometimes 2 Fawn. After their first year, Fawn are know as Yearlings.
The deer have to face a very harsh winter no matter what. Even though their winter coats protect them from wind and snow food shortage may kill them. Some deer migrate many miles to warmer places and to give birth. Some deer store up food for when the snow is to deep to look for some.
Life Cycle ( Early life )
When the Doe gives birth, the Fawn is born with its eyes open. Until it is able to run with its mother, it lies hidden in the grass. Young deer are especially vulnerable to predators like Timber wolves and Bobcats
Life Cycle ( Older ages )
Before mating, the Bucks fight each other with their antlers for the females. Some deer mark their territory before mating. For example, the Roe deer fray the saplings with their antlers before mating on the outside of their marked territory.
Deer give birth to one fawn. They mature at around 15 to 28 months. They range from grasslands,deserts and forests. They belong to the specie Cervus. Their top speed on land is 40 miles per hour and their top speed in the water is 13 miles per hour. Deer do not hibernate. The male deer grow antlers and their track shape is a heart.
Moose give birth to two calves. They mature at around two years. They range from Colorado north through Canada and Alaska. They belong to the specie Alces Alces. Their top speed on land is 35 miles per hour and their top speed in the water is 6 miles per hour. Moose do not hibernate. The male grow antlers and they also have heart shaped tracks
You've probably seen deer next to the road or deer crossing signs so you don't hit a deer. Did you know that still, there are 1.23 million deer/car collisions a year costing 4 billion dollars in car damage. This happens because when deer see the car coming they freeze. Deer/car collisions happen when the deer are migrating. To cut down on the deer population, people have hunting seasons to hunt deer, they can eat the deer meat and even save lives.
The Harsh Winters
When winter comes, the deer do their best to prepare for it and survive and some do not. If the Fawns are born too early they cannot survive the harsh winter and if they are born to late they are not strong enough to survive. Bucks, Does and Fawns may also die because if they don't store up enough fat and food they might get stuck in the thick snow and die of hunger.
