Why do animals hibernate?

Is this big sleep really as good as it sounds?

Hibernation is an adaptation that helps many animals conserve energy by remaining inactive, greatly slowing their metabolism and reducing their body temperature for days, weeks or even months at a time.

Why do animals hibernate?Typically, animals hibernate in order to survive long periods when food is scarce. Hibernating creatures will generally eat a lot of food before hibernation and then survive off the energy stored in their fat.

The physical changes involved in hibernation are far more extreme than what happens during sleep. For some critters, hibernation doesn’t even appear to be restful; indeed, some can emerge exhausted and have to catch up on sleep to recover!

    My dog loves to look up at birds flying overhead. He will be laying on the deck and see a shadow pass overhead and jump up barking and chasing the bird in the sky. Not all dogs do this. Some you can not coax into looking up at the sky. they just don’t get it. but my dog loves looking at birds in the sky and chasing them barking!! Inside you can see him moving his eyes within a certain radius just as we do.
