Hedgehog in autumn leavesAt this time of the year, some wild animals – including me – will be fast asleepzzzzzzzzzzz

All my hedgehog friends and family hibernate through the winter months, along with bats and dormice. The reason why these creatures hibernate is purely down to the lack of food available during winter.

We hedgehogs rely on invertebrates (worms and insects) to keep us going, but when the temperatures drop below zero, the food source dries up. So hibernation is the only answer.

Bats survive on insects such as mosquitoes, gnats, and moths and how many of these do you see in the winter?! Nope, many flying insects simply aren’t about during the colder months, so bats too must hibernate.

Dormice hibernate during the winter months.

Dormice feed on flowers, pollen, fruit, insects and nuts. And as these are scarce during the colder months, dormice also hibernate.

So what is hibernation? It’s when an animal is more than just asleep; its heart rate drops from 190 beats per minute just barely 20, its body temperature drops to just 10 degrees Celsius and it hardly breathes at all. It burns very little fat, which means it can survive until spring. Hibernation is one of nature’s miracles and it keeps some mammals alive through winter.

Isn’t nature amazing?


I'm Eric. A few years ago I was run over by a lawnmower. I still have nightmares about it now... But I'm much better and very happy roaming around - I just get a bit spooked sometimes. I'm here to tell you lots of important things about the RSPCA and animals and I might even do a few reviews. I hope you enjoy my posts.
