Forest dwellers – hares – do not swarm burrows and do not have a permanent den. Stocks for winter these animals do not harvest, they feed on small spines, extracting them from under snow, gnawing bark and young trees. And all the hare preparation for winter is about changing the colour of their skins – from grey to white after moulting. It helps in winter to disguise themselves from predators.
Active preparation of stocks for winter is engaged in proteins and other small rodents . They prey on acorns, mushrooms, nuts and hide them under fallen foliage or hang on tree branches. In winter hibernation, squirrels do not lie, although they may sleep several days in a row during frost.
Hamsters, slurries, badgers and hedgehogs fall into long sleep. Also until spring, the bear sleeps. All its winter reserves are in subcutaneous fat, it is eaten before the onset of hibernation. Insects carry winter differently. Some of them swarm burrows, others may exist even in severe frosts.
In late autumn, some birds fly off into warm edges and others winter on trees, getting thicker plumage. First the native edges leave the cranes, then it is time for hives, wagtails and wagtails. From waterfowls to the south, geese and ducks are also sent as reservoirs begin to freeze.
On the wintering fly even some city crows, moving away to the distance up to two thousand kilometers. And yet most crows remain for winter in habitats. Surviving them helps omnivore. These birds can feed on fruits, grains, greens, empower nests, stealing eggs and chicks, can destroy some rodents, do not squeamish the fall. All this helps them survive even in harsh conditions.
In winter, animals warm in different ways. They are heated by fur, wool, layers of fat, protecting skin and internal organs from hypothermia. Also during winter, the metabolism of animals that do not hibernate becomes more intense, increasing the production of heat in the body and compensating for heat transfer.
