We should design them to have owl like wings. Owls fly very quietly.

  You should definitely watch this: https://www.youtube.com/watch?v=lVo3wEkyci4 https://www.youtube.com/watch?v=lVo3wEkyci4 and https://www.youtube.com/watch?v=nnR8fDW3Ilo https://www.youtube.com/watch?v=nnR8fDW3Ilo Also, while birds are really good at using their wings to glide and provide propulsion flapping designs that need to lift much more than their own weight have so far not worked very well. So I don't really see them as viable for packages.

    Interesting. Seems like some birds can lift a lot of weight though like a hawk carrying a rabbit.

      Yes, but for a given weight in flight so far nature seems to be doing much better than batteries or fuel when it comes to carrying capacity. That's not to say that will not change, but for now biology has the edge, especially when you compound the problem such as limit the noise emitted.
