Corvids possess highly developed cognitive abilities and can recognize, remember, and actively hold grudges against specific human faces for several years. Researchers discovered that if a person threatens or captures a crow, the bird will not only scold that specific individual upon future encounters but will also communicate this threat to its flock, turning the entire neighborhood of birds against the offender. It is delightfully terrifying to realize that a brain the size of a walnut is capable of maintaining a multi-generational vendetta just because you looked at a bird the wrong way on your morning commute. You can delete your digital footprint and hide from human authorities, but if you disrespect a crow, you are permanently blacklisted by the local avian mafia until the end of time
