Birb is internet slang for a small, round or especially cute bird, and clips like this spread because the word itself signals the joke before the sound plays. This red birb, identified in the original description as Gumi, became a shareable soundboard clip through its looping wue calls and fixed stare, which editors reuse as shorthand for blank confusion. Rather than a line from a film or show, its popularity comes from repeat use in meme edits, reaction videos and pet posts where a cute animal doing almost nothing says everything.
