A prototype electric snowmobile and old-school wooden skis open up Sweden’s backcountry as our writer goes on the hunt for local wildlife

On the slopes up to the ridge, the snow is deep and fresh. Long frozen arms of it hug the trees. Behind us the tracks of our skis gleam with a strange blue light, and in front, delicately drawn into the snow, is the perfect feathery imprint of a bird – like a pale icy fossil. My guide, Jens Sarlin, from Next Step Nature, stops. “Capercaillie,” he says. “It was feeding on pine needles up top and has landed here, then dug a burrow in the snow. It may still be there.”

We edge forwards. A trail of bird footprints lead to a hole, but it’s empty except for some droppings. “They dig down and then sideways to fool the foxes,” says Jens. We move forwards again, silent on our hunters’ skis, antique wooden heirlooms that slip easily over deep soft snow. What we are hunting, with cameras only, is something rarely seen – the wolverine – and Jens knows the best places to find them.
