Misconceptions About Opossum Hibernation

It’s also thought they dig their homes. But they usually take over spots left by other animals.

Differences Between Hibernation and Dormancy

Hibernation and dormancy are not the same. Hibernators “shut down” their body functions. Dormant animals like opossums keep a stable body temperature and stay alert.

Opossums change what they eat to survive the cold. They eat almost anything they can find, like trash or pet food. This helps them stay alive when it’s harder to find food.

Even though opossums don’t hibernate, they have ways to get through the winter. Their dormancy and flexible diet play key roles in their survival.

Natural Shelters: Logs and Trees

Opossums like natural spots like logs, trees, and rock holes for warmth. These places keep them safe from enemies and bad weather. They also use burrows from other animals as a good opossum shelter.

Man-Made Shelters: Basements and Garages

When it’s really snowy, opossums sometimes go into human places to find warmth. They sneak into basements, garages, and attics to escape the cold. These spots often become a comfy opossum shelter for them.

To stop them from coming in, it’s smart to block those areas off. This helps keep both sides happy.

Opossums are really clever in finding shelter for the winter. They can handle both the wild and places made by humans. This skill is key for them to make it through the cold season.

Challenges Opossums Balance with Frostbite

Opossums face big problems with frostbite when they move into colder places like central and southern Maine, central New Hampshire, and Vermont. The coldest parts, like ears and tails, get hurt because they don’t have much fur. This often results in damage after being in the cold too long.

Virginia opossums are out in the cold because they don’t sleep away the winter. This makes them more likely to get frostbite, which can mean losing parts of their bodies. Besides frostbite, they also have to deal with a short life – usually only 36 months in the wild.

Even with these troubles, opossums are moving further north, even to Ontario. But living close to humans brings other dangers like cars and predators. Research shows cars kill 35% of opossums tracked with radios or tags, and traps kill another 13%. These challenges, along with the cold, show how hard winter is for opossums.
