Airplanes were invented in 1903 and we still don’t have a scanner that can copy birds.
To keep the metaphor precise, we’d need only to copy the bird’s technology of flight, which is its physical shape and its flying technique, not the whole internal structure. The reason we don’t do it is that we already have better means of air transportation, rather than unfeasibility of bird emulation.

And we do, in fact, have toys that achieve flight by being bird-shaped and flapping their wings.
