Ouch! Hedgehog Day highlights these loveable creatures but heeds this word of warning – don’t get too close! Yet while hedgehogs certainly know how to defend themselves, we can all still do our bit to help protect them, and what better time to start than on Hedgehog Day…

Fascinating facts about the humble hedgehog

In total there are 14 species of hedgehog around the world, largely concentrated in Europe, Africa, and Asia. These nocturnal and solitary creatures are most commonly found in green spaces such as gardens, woods, and parks – of course, hedges are a particularly popular haunt for these mammals, which, combined with their small snouts and piglike snuffling, is where they got their name!  

As we all know hedgehogs are covered in spines, but what you may not have known is that these spines are actually hollow hairs stiffened by keratin. Hedgehogs use their many spines (around 5,000 when fully grown!) as a defense mechanism when under threat by rolling into a tight ball so that all the spikes point outwards. What is less well known is that they also use them for cheese and pineapple during cocktail parties (although there is yet to be any photographic evidence of this…!).

Hedgehogs rely heavily on their sense of smell; they can detect food under an inch of soil and can often sense the presence of danger. They’re omnivores, best known for snacking on creepy crawlies such as earthworms, slugs, and caterpillars, but they also eat delicacies such as mushrooms, berries, small frogs, and bird eggs. They tend to search for food at night and can travel a distance of 2-3 KMs.

One very strange fact about hedgehogs is that they self-anoint – this seems to be connected with irregular smells or tastes making them create large quantities of frothy saliva which they then flick over their spines with their tongue (please do not disturb a hedgehog in the middle of this process, it’s like catching someone in the shower).  

While self-anointing might not be one of their most endearing features, the fact that baby hedgehogs are called hoglets most certainly is! Hoglet litters are born in late spring/early summer and the young spend around a month in their parents’ nest before setting off into the big wide world.

History of Hedgehog Day

Hedgehog Day is a Roman tradition preceding the modern ‘Groundhog Day’. While groundhogs are native to North America, various animals have been used in Europe to help predict the end of winter and the coming of spring, including the hedgehog. The Ancient Roman tradition passed down into other European folklore, in particular in Ireland. If a hedgehog was seen at the start of February it was thought to be a sign of good weather and a promise of warmer days, whereas a no-show from hedgehogs meant winter was sure to continue for several more weeks.

In hindsight, this may not have been an especially reliable method of weather forecasting, especially given that hedgehogs tend to hibernate from November through to the middle of March! They do however emerge from hibernation periodically during these months to change nesting sites, so any ancient weather watchers most likely spotted hedgehogs simply going elsewhere to carry on hibernating.

In fact, hibernating is a risky business for these animals. Sadly, up to around two-thirds of hedgehogs won’t make it through their first winter, especially if food has been scarce. Their body temperature, breathing, and heart rate drops dramatically (to as little as two beats per minute), and it’s vital that they stock up on enough food before winter to keep them going until spring.

Hedgehog Day also tied in with the US release date for Sonic the Hedgehog 3 in 1994. There have been a number of famous hedgehogs in popular culture, with Sonic probably the most well-known – he’s certainly the fastest, and this electric blue character has featured in a series of Japanese video games as well as his own movie. The British children’s author Beatrix Potter created Mrs. Tiggy-Winkle, another well-known hedgehog who happens to be extremely good at laundry. And the hedgehog has been popular throughout history, whether the subject of parables and poems, worshipped as sacred or thought to hold valuable medicinal qualities.

How to celebrate Hedgehog Day

Perhaps the best way to celebrate Hedgehog Day is to help protect these prickly yet adorable creatures. In some parts of the world, particularly Europe, hedgehog numbers are sadly declining – this appears to be due to a variety of complex factors such as habitat loss through urbanization and agriculture, food scarcity due to pesticide use, and disease caused by parasites.

If you’re lucky enough to have a garden – prime hedgehog habitat – then why not make it hedgehog safe? Always check for spiny visitors before mowing your lawn and allow an escape route from your pond or water feature. Check bonfires before lighting them as these are another popular hiding place for hedgehogs and take care with netting as they can easily get tangled! If you come across a hedgehog in need of help, keep it warm and offer it cat or dog food along with freshwater – this is much better than giving it milk and bread. You can then either take it to a local rescue center or, if it’s perked up, release it back into the wild.

And there are plenty of things you can do to go the extra mile and make your garden, even more, hedgehog friendly. Each individual will have its own home range of up to 30 hectares, so hedgehog highways are especially important in urban areas – creating gaps through or tunnels under fences between your garden and your neighbors’ will ensure that hedgehogs can roam far and wide for food. Growing a wide range of plants will increase the insect population in your garden, offering up a delicious feast for any passing hedgehog. And you can even encourage them to settle in your garden, either by piling up some logs and leaves for a cozy nest or by building a small hedgehog home – you’ll find plenty of great instructions for these online!

Hedgehog cakes are very fun to bake, especially with children, and if you’re really serious about protecting the hedgehog you could even sell your cakes to fundraise for a hedgehog preservation charity! You can also sign up for a citizen science project to help monitor numbers and some organizations and charities offer the chance to adopt a hedgehog for yourself or a loved one.

However, you celebrate it’s sure to be a spine-tacular day!
