The exact recording behind seven thousand pigeons is not tied to a confirmed film, anime or game release, and the title appears to come from soundboard sharing rather than an official soundtrack. Online, the phrase works because it promises a ridiculous number and the audio delivers a dense wall of cooing and wings to match. It has settled into meme editing as a quick way to exaggerate any bird, crowd or swarm moment, especially when one pigeon would be too calm for the joke.
