The American woodcock is a real North American bird, and its short peent call is what most people are hearing in this clip. Online, that odd little vocal sound spread beyond birdwatching circles because it feels both authentic and absurdly comedic in short edits. Creators use it as a clean non-sequitur, especially when a video needs a tiny unexpected noise instead of a big impact effect. Its staying power comes from that contrast: it is a genuine wildlife call that lands like a joke.
