No - you can watch it flap its wings if you zoom in while running the video. As for size - you realize that depends on how far away it is. Presumably you are assuming that it is near ground level. It isn't - it is much closer to the drone.Better look again. Definitely an airplane. Birds do not fly in such a straight line, and....that would have had to be the largest bird in history to be that size. 'Twas an airplane, single engine, private.
You can also calculate its speed as a function of altitude. If it is a low-flying aircraft, as you are proposing, then from just after entering the field of view on the right, it covered 980 meters in 3 seconds. That's 327 m/s (730 mph), or almost exactly Mach 1. Pretty impressive for a single-engine private aircraft.
