Interesting subject . I have thought about this very subject. I do believe that faster pigeons have always been the goal however the real goal was to have 500+ milers in the loft but after the war the Belgians had little money and developed sprinters and betted on these heavily so sprinters became a valuable commodity rather than having birds that won well at 500+ miles . No-one has actually worked out how pigeons home but can only guess . One is via the sun , the next via landmarks / magnetism . Now most of this seasons races have been in fully overcast conditions so basically the birds that orientate via the sun are disorientated and wonder about with no real hope of getting home , whilst the birds that orientate via landmarks are the ones that are making it home. For some reason feds / organisations have moved there race points further west ours included , with the East wind this is pushing them further west look at the high number of birds reported just on this site in Ireland . Well if family of birds have been developed to fly a certain route these will not fair the same on a different route . Different racing always requires a different sort of bird . It's just as has been said many have developed the high velocity blow home birds that don't get tested in hard winds . It's these type of birds that win week in and out but with the bad weather we've been having they've been dropping like fly's , I'am not saying these birds are inferior I'am saying these are the birds in most peoples loft . Rest is as good as training when the weather is from north or east as the saying goes north n east not fit fer man nor beast .
