Birds chirping is a widely used ambient sound effect rather than a clip tied to one specific character or franchise. Short recordings of bird tweets have been common in video editing, animation, games, and meme posts for years because they instantly signal morning, nature, or calm. Online, this kind of sound also gets used as a contrast joke, especially when a noisy or dramatic moment suddenly cuts to complete peace. Its simplicity keeps it useful across both sincere nature edits and comedic timing.
