I don't see any way this could be real, personally. As a previous owner of pigeons, they don't generally fly to random places. You release them somewhere and they fly to a place they KNOW (their coop generally). That in and of itself is amazing, but yeah, I don't know any way you'd be able to get them to fly random places... not to mention predatory birds and such.
Also, even if it was 'real' at some point, none of their stuff has been updated at all since 2015/2016.
