racer pigeons Hazards
As pigeon racing takes place over great distances in the sky, instead of on a racetrack, there are many hazards that could befall a pigeon during racing as well as training. The main hazard encountered by racing pigeons is predation by birds of prey.[11][12] The killing of valuable pigeons by wild predators has led to some pigeon fanciers being suspected of killing birds of prey such as falcons.[13]
Another hazard that racing pigeons encounter is flying into objects they sometimes cannot see, mostly when flying at high speeds or in darker weather conditions. The most common obstructions are electricity pylons or TV aerials.[14] Pigeon fanciers will often have one of their pigeons return home with wounds or missing feathers from the belly or flanks region.
It is thought that racing pigeons rely on the Earth's magnetic field to find their way home. Some evidence has surfaced indicating that mobile phone towers may be interrupting the birds' navigation,[15] although no published research has investigated this theory.
