When do hedgehogs hibernate in winter?

The humble hedgehog is one of Britain’s favorite wildlife, but it is declining in the county, with its population declining by two-thirds since the 1990s.

It is estimated that hedgehogs die each year in hibernation, as this is the case when they are at their weakest, but the process of hibernation may vary in different habitats.

When do hedgehogs hibernate in winter?

These tiny mammals need energy to grow and move, which they get from beetles, caterpillars and other insects.

When the weather gets cold, they decide to store this energy, as it becomes more difficult to find their food supply.

They store energy by moving, cooling their bodies and slowing down their heartbeat.

Hibernation usually occurs around October / November and continues all the way through the cold season, although some hedgehogs may be active during mild winters until December.

During hibernation, the hedgehog’s energy supply comes from the fat stores it makes in the summer, which means eating plenty of food while still having heat outside.

Hedgehogs can be extremely dangerous when hibernating, as they will use valuable energy reserves to reactivate.

If you accidentally disrupt the hibernation nest, cover it with a thick layer of dry leaves and perhaps leave dog food and water nearby, so the hedgehog can easily find an energy supply before To find a new hibernation site.

Where do hedgehogs live during the winter?

Hedgehogs generally prefer forests and build nests in hedgehogs and suburban habitats where they can find plenty of food.

More arable land, moreland and dense forests are less ideal habitats for hedgehogs, and as more people choose astroturf and manicured lawns, it becomes more difficult for them to find a home in our backyards.

At the end of autumn, hedgehogs will consider the best places to build nests for hibernation.

They will sleep happily in the winter months, including hedges, log piles, under sheds, in piles of leaves

When do hedgehogs leave hibernation?

Hedgehogs live in hibernation around March, but it depends on the weather, location and the individual hedgehog.

In the UK, hedgehogs usually come out of hibernation between March and May, with mammals emerging later and moving further north.

Men usually come out of hibernation first in March, women wake up about two weeks to a month later.

The activation process can take up to 12 hours, and a new emerging hedgehog can be quite confusing for a day or two.

This makes it a dangerous time of year to get out of hibernation, as a tangled and hesitant hedgehog is more likely than ever to get into trouble.

They become weak after losing about 25% of their body weight, which makes them in urgent need of sustenance, weak for predators and more likely to get entangled or confused in things.

People are encouraged to look for a hedgehog at this time of year, as if you see a hedgehog during the day, maybe it’s bad and needs care.
