Murder of crows is a collective name for a group of crows, and their harsh calls have long been used in horror and Halloween media to suggest dread and bad omens. This clip is a short, standalone crow sound effect of the kind shared widely on soundboards and used by video editors for spooky projects, rather than a line from a specific film or show. Its popularity comes from how instantly recognisable the sound is, making it a quick shorthand for haunted places, dark forests, and eerie autumn nights.
