This clip is a reversed edit of a duck army sound rather than a recording from a film, show or game, and its appeal comes from that simple twist. Reversing familiar audio is a long-running online joke, because it keeps the original recognisable while making it sound wrong in a funny way. Duck sounds already carry a chaotic, cartoonish energy, so playing a whole flock backwards turns a march into a retreat and gives editors an easy punchline. It continues to appear in short videos and meme edits where an unexpected rewind or failed charge needs an instantly odd sound.
