Different animals, with different levelsWhile many different species hibernate, a good number so remarkable in different ways. Some animals are referred to as' true hibernators, "that is, they provide an extremely deep sleep with an abnormally low heart rate, body temperature drops to almost freezing point of water.
Some mammals to sleep less deeply and regularly monitored during the winter. American squirrel looking for food about once every four days awake, and the British Hedgehog was announced that hibernation to rely on particularly warm days, if they can afford the energy consumption. Birds give a very light state of calm as solidification, where they just lower their temperature and energy consumption at will known. This allows them to wake up easier and avoid predators. Grizzly bears mark an exception to the pattern. You enter a low power state for up to seven months without waking, but are capable of waking up immediately defend against predators, a strange mixture of long and short-term hibernation torpor.

RecoveryDepending on the level of the animal enters hibernation, the body temperature changes dramatically. However, one constant that remains the same is the fact that it always seems to take a drastic decline. Warming the body takes a large amount of energy, which is why humans and dogs more food in the winter (assuming they are left outside) need, it allows us to maintain the temperature needed to keep it in order to survive. In hibernating animals, the removal of this requirement allows them to save energy. The bat, for example, can often be seen at a body temperature close to zero degrees Celsius, combined with a heart rate of 10 bpm only will possess. This story is divided in many reptiles and small mammals.
Birds with their brief states of solidification, are only capable of reducing their body temperature of around 40 percent, although this enough to conserve a little energy in the winter. Grizzly bears made recent news for the administration to maintain a high body temperature with a low metabolism, an odd exception, which is not yet fully understood.
If you see an animal in hibernation, it is best to leave it be. Let amphibians covered, and do not disturb the resting places of smaller mammals. There are still a lot on the specifics of hibernation to be learned, especially when the rejection trend grizzlies are anything to go by. Nevertheless, it is interesting the process takes place, to consider in your garden every year.
