Well birds are pretty hard-wired, as it happens, so most of that is already in their DNA, but to supplement it, part of Ben's idea is to use homing pigeons to help train the young passenger pigeons how to flock and how to find their way to their old nesting grounds and feeding grounds.
Pticama je to urođeno pa je većina toga u njihovom DNK. Ali kako bi to nadopunio, dio Benove ideje je koristiti golubove pismonoše da bi trenirali mlade golubove selce kako formirati jato te kako pronaći stara područja gniježđenja i hranjenja.
