Fortunately, for innocent passersby, there are often signs that a moose is perturbed and likely to charge. First, take a look at the ears. Most of the time, a moose’s ears will flick this way and that, but if they are pinned backwards, the animal is agitated and it’s time to walk away quickly. Next, to further warn you that the animal wants its space, the hair on its shoulders will stand up on end like a growling dog or a hissing cat. Finally, if the moose licks its lips, it means it’s about to charge and, “you should be finding some other place to be,” Lampi says.
