Crow calls are a staple of stock sound libraries, where short nature recordings are shared for use in film, games and online videos. Because a crow's caw is instantly recognisable, editors have used it for decades to signal wilderness, foreboding or the arrival of something unsettling, from horror scenes to cartoon graveyards. Online, the same two-second clip works as a quick, reusable cue in memes, edits and short videos, where its familiar, slightly ominous tone lands immediately without needing any explanation or context.
