Loved your answer, Mr. Peepers! ❤️️ Actually, I used to fold paper airplanes, as well -- and I'm sure a BIRB-airplane could be designed with origami, that could be flown quite well. And as for an action of an origami birb that can flap its wings -- I once folded one of these models, as well -- based on the traditional origami paper crane (the good luck birb!)
Now, I must mention, Mr. Peepers, after your birb model is completed, you will be able to make the wings flap by pulling its tail. But this does not mean, by any means, that if you try to toss your paper crane across the room, it will take flight.
