What are the 5 stages to hibernation?

The annual cycle of black bear activity and hibernation has five stages:

  • hibernation.
  • walking hibernation.
  • normal activity.
  • hyperphagia.
  • fall transition.

What is hibernation season?

Hibernation is a state of minimal activity and metabolic depression. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It most commonly occurs during winter months. The equivalent during the summer months is aestivation.

How long is the hibernation period?

Hibernation can last anywhere from a period of days to weeks to even months, depending on the species. Some animals, like groundhogs, hibernate for as long as 150 days, according to the National Wildlife Federation. Animals such as these are considered true hibernators.

Do bears go to the bathroom during hibernation?

Grizzly bears and black bears generally do not eat, drink, defecate, or urinate during hibernation. Bears continue to produce some feces during hibernation yet they do not defecate (Rogers 1981).

Why do bears eat so much before hibernation?

During the fall months, bears eat and drink nearly nonstop. They need to put on weight to prepare for winter and hibernation. This process is called hyperphagia. Bears that eat human food can lose their preference for natural food sources and their fear of humans.

Does hibernation end in spring?

Though there’s no pinpointing the day hibernation ends, the timing in which wildlife emerge from their sleep can be predicted to an extent. Most animals stop hibernating during the spring because that’s when the days get longer and temperatures rise, meaning more food sources are available.

Do you age in hibernation?

When animals hibernate, their body temperature and metabolism drops, reducing the amount of energy they require. But while this suggests hibernation slows the rate of ageing, the longer life span could be due to some other factor, says Turbill.
