Autumn is a transitional season from hot season to cold. At this time, cardinal changes occur in nature: the air temperature drops and the daylight hours are reduced, the leaves fall and the grass turns yellow, the migratory birds and bats migrate, insects and mammals are prepared for winter. Those types of fauna that remain in temperate latitudes for the winter behave differently:
Of greatest interest is how animals are preparing for winter.
Winter hibernation and coloring
Depending on species, various animals are prepared in their own way for winter. Some of them fall into winter hibernation:
Many animals change color for the winter. So ermine, tundra partridges, northern deer, hares and arctic foxes become white by winter, so they merge with the landscape, which allows them to hide from predators. Sometimes it happens that close species do not equally change the color. It also depends on geographical latitude. They and the same representatives can change the color in different ways if seasonal changes and living conditions specifically require the area.
Nourishing reserves for the winter
Many animal species make grocery reserves for the winter. Mice and hamsters, fields and other rodents collect grain crops. Proteins collect mushrooms, acorns and nuts. Burundunes make cedar nuts and seeds for the winter. Rodents such as haystings stock up haystacks for the winter, in which various herbs are collected and neatly composed.
Born animals also harvest food for the winter. Ermine and affection in holes collect 2-3 dozen mice. Black Hori storage a large number of frogs. For food, mink prepare several kilograms of different fish for themselves. Bears, Wolverine and Kunits are hiding food in the branches of trees, in stones and burrows, depending on their wintering places.
All representatives of the animal world are preparing for frosts in the fall. Some accumulate fat and fall into prolonged sleep, others stock up in minks, and others change the cold climate to warm and favorable. Each type of fauna has its own devices that allow them to adapt to harsh conditions and survive.
