Crows have an unforgiving memory. They never forget and they can turn into a person’s worst nightmare if they have ever been harmed by that person. The crow is proven to be an extremely intelligent bird. However, if you harm in it any way, this intelligence might turn against you in a very unpleasant way. Studies have shown that the crow’s memory is able to store the facial features of a person if that person ever dared to ruffle its feathers.
A professor from University of Washington’s School of Forest Resources decided to conduct a team of colleagues in order to test this theory. The results were clear: regardless of the time gone by, the area of the world or the face features of the person, the crow still remembered that person as its Nemesis.
If you ever do wrong to a crow, it won’t stop until you have paid for what you’ve done. Furthermore, it will scold until it attracts other nearby birds. They will immediately exchange information about the “dangerous” person and will get revenge on them.
