Bull elk can be particularly aggressive during late summer and early fall, as one driver learned the hard way at Jasper National Park in Canada. The animals are currently in their mating season (known as the rut), when males compete for dominance by displaying their antlers, bugling, and sometimes fighting rivals. It's a spectacular sight, but even careful drivers may find themselves facing a repair bill if a particularly aggressive bull takes a dislike to their vehicle.

A video of this particular incident (which you can see below) was shared online this week via Instagram account . The account usually documents instances of bad behavior at sites of natural beauty around the world, often involving wildlife, but sometimes people just get unlucky. "What the video does not show is that the bull elk came from the left side of the highway so traffic stopped to let it go across," explained photographer , who shot the footage last September.

"But, the cows were on the right side of the highway and the bull saw that car as being in between him and his cows so he became aggressive. Just acting his natural behaviour and unfortunately this car was in his way. " "Though they might not appear threatening, elk can be aggressive and attack without warning," warns people planning a visit to Jasper.

"In the spring calving season (May - June) female elk aggressively defend their young. During the fall mating season (Aug - Sept), male elk are particularly belligerent. Do not approach elk in any.
