So basically the pigeon is sending an Echo request, but surely there would need to be some sort of return path for the Echo reply to get back to the original sender (such as another pigeon going the other way, or someone sending the Echo reply in the post etc)?It's a /homing/ pigeon. There and back I believe, with their barcodes. Read more on the rfc.
I was always under the impression that the way homing pigeons worked was that they were driven out to a field in the middle of nowhere (often say 100 miles or so from 'home') and are set free and they fly home (homing) and in the terms of racing homing pigeons, the ones that get home quickest are the winners. I don't think it's a case of they are let out of their home, fly somewhere and then fly home.
Of course I could be wrong, it's been years since I saw something on TV about homing pigeons (I think it was Words and Pictures in the 80's).
