Birds have feathered wings and everything about their lightweight structureis made for flight and speed. A birds feathers are hollow and contain as much air as matter. A bird has a light beak, not a heavy jawbone. A bird has a fan tail that acts as a rudder and brake. I could go on and on and so could anyone else but to what point? Yes birds can travel at faster fps than flies.
The mistake in your point is comparing your dragon to the bird and the dryad to the fly. The drad is actually MUCH more like the bird than you are, both having two legs and being devoid of your heavy frame. You are more like the fly. And yes, inadvertently as it is you have thus reinforced my point. Im afraid it as at my own expense though, for indulging you in arguing the most stupid of topics. Next time provide something with more base.
