I have heard Migrating birds all over the world are having same issues as well as sea creatures even bees they believe it has alot to do with the earth magnetic field change If true this obviously will effect the homing instinct of our pigeons no matter if 50 miles or 500 miles Birds and animals sea creature must be able to overcome or adapt to the change over time As turles ect have been around for many years and survived through these changes therefore obviously adapted to make it back to breeding islands But this makes me even more puzzled if this was reason why so many get lost yet many still get home Is it that the birds returning have the stronger homing sense and overcoming tbe change I hear many saying cant be cause i lost great birds that had flown channel many times before These neverseen again great birds if above corect these champions would be home as they had great homing insticts but dont forget bop may have nailed these champions as we all know thats also a massive man made problem Whatever it is our birds are up against it From the best flyer to the average flyer Noone seems to be escaping it if truth be told
