To begin with, let's dispel the myth that bears wake up from hibernation on Tiburtius Day, April 14. 

World Wildlife Fund predator expert Benny Gäfvert explains that the bears have jumped the gun.

– We have evidence, various kinds of tracks, indicating that they've probably been awake for a while, he says.

As the bears now make themselves known after about six months in hibernation, it's conceivable that they're grumpy. But that doesn't necessarily mean you have to be extra cautious when venturing into the woods.

– Of course, they're hungry after sleeping for six months. They're looking for food and will eat just about anything. But they're not aggressive, as long as they're not provoked. You should make enough noise that the bear knows to avoid you.

So, what should you do if you do encounter a bear? Benny has the answer.

– Make yourself known. Speak calmly. You should retreat slowly, facing the bear, in the same direction you came from, he says.
