Big and shy
It is often large animals that humans are most afraid of. Although people are sometimes injured by, for example, bears, the animals are usually more interested in staying away from us, says Didrik Vanhoenacker, duty biologist at the Swedish Museum of Natural History.
You have to be aware that wild animals are wild animals. You should never approach an animal to get a close-up photo with your mobile phone. Any animal can defend itself.
Bloodthirsty man-eaters
They actually exist. Mosquitoes, gnats and midges all have females that feed on blood to nourish their eggs. Ticks and head lice also like to nibble on us.
Another one lurks in the water - the leech.
If you splash your feet in a pond, they may come swimming.
Battles for the nest
Wasps, bees, bumblebees and ants do not hesitate to go into battle for their nests. Stings are the most common weapon, but carpenter ants bite and spray formic acid.
Ants can also send out alarm scents to summon help.
So they think, "Oh shit, someone's attacking us! We can smell it, we're coming, we're coming, hold on!" and try to send out more and more.
Defending bird parents
Several bird species are known to aggressively defend their nests.
The one that is most aggressive towards humans is probably the barn owl. You have to wear a downhill helmet and ski goggles when ringing the chicks because it attacks and hits hard on the head.
Herring gulls and terns like to dive to scare away intruders. The blackbird has a different tactic.
They don't have sharp claws or anything like that, they just drop bombs and poop.
The lemming is aggressive
"One animal that has a reputation for being aggressive is the lemming. It may be an extra stress factor during a lemming year," says Didrik Vanhoenacker.
Then they will probably be more aggressive and more easily provoked than they normally are. There are lemmings everywhere, so it will be a bit like "Falling Down".
Capercaillie with cock's eye
The capercaillie is in a class of its own. Didrik Vanhoenacker describes it as the behaviour of some male capercaillies.
The capercaillies have a mating season where the males fight each other. Then they not only fight with other capercaillies but also with people. They will attack us because we can be a competitor for the capercaillie hens.
