Cooing sounds from doves and pigeons have long been used in film, animation and games as a shorthand for calm outdoor settings, and short clips like this one spread through soundboards and video editing libraries. Creators reuse the gentle coo coo pattern because it is instantly recognizable as a bird without being distracting, making it useful for nature documentaries, kids content, ASMR and parody scenes. Its simplicity keeps it popular for memes where a peaceful moment is set up before a sudden contrast or punchline.
