With no single credited source attached to this clip, it circulates mainly as a short, shareable sound effect passed around in chats and soundboard collections. Its appeal comes from the contrast between the bird-like whistle and the sudden scream, a combination that reads instantly as alarm, surprise or over-the-top drama without needing any dialogue. Creators keep reusing it because it is short, easy to drop into an edit and immediately recognisable in context, especially for reaction clips, memes and exaggerated reveals where a normal sound would feel too flat.
