PEOPLE are being asked to sign up to 12 Days Wild, a festive nature challenge, by the Herts and Middlesex Wildlife Trust.

It runs from Christmas Day until January 5, with the idea of doing one wild thing every day or night.

Everyone who signs up will receive daily inspirational emails, with ideas and activities to enhance wellbeing, such as embracing winter walks in nature or experiencing the magic of star gazing.

BBC TV presenter and Wildlife Trust vice-president Iolo Williams said: “From dawn to dusk, winter wildlife is busy all around us.

“Otters are always up early and, if you see a trail of bubbles in the water, you’ll know they’ve spotted you first.

“Night-hunting barn owls venture out on cold winter days to find extra food and will woosh past you in the winter sun.

“Then, at dusk, starlings gather in the sky, forming ever-shifting shapes and patterns known as murmurations.

"There are so many wildlife adventures to be had during 12 Days Wild – I hope you enjoy them.

Lea Ellis, engagement manager at Herts and Middlesex Wildlife Trust, added: "At this time  of  year, it's easy to think there's not much worth going out for.

“But even on a grey day we can all be boosted by the natural light and getting outdoors, or even taking it in through an open window.

“My tip for 12 Days Wild would be to embrace all weathers and be mindful of how it makes you feel with the sun on your face, raindrops falling off your nose or, the rosy glow the cold gives your cheeks.

“Look for colour in the remnants of autumn leaves, the bright red berries on holly tree, and admire the stunning winter sunsets.”

Spending time in nature is proven to help people feel happier and healthier.

A Wildlife Trusts survey found that those taking part in the 30 Days Wild summer challenge felt 56% more connected to nature after taking part, and that it boosted their health by an average of 30%.
