How do pigeons navigate?
« on: 05/11/2012 22:15:58 »
Do scientists need to be hit between the eyes with a hammer to gain their attention ?
After explaining to a Cambridge graduate that homing pigeons that are mated on the same day lay their eggs ten days later and will do so simultaneously and with split second accuracy. I got the answer that It has been proved that pigeons don't have a body clock ??? Then, after telling the same scientist that I can show that pigeons also have a biological sextant that is both macroscopic  and easily demonstrable, I got the answer "That cant be true as the consensus is that pigeons use magnetic field lines to navigate!"  Is research a dying art, or has some momentous discovery been made regarding this subject, that is being kept secret?

I'm sure it is now established that as they approach their home base, pigeons make for obvious  landscape features and even follow roads, when it would be shorter to fly directly.  I read that they have even been recorded as flying roundabouts. (I must add disapprovingly, no signals). Sorry. clumsy attempt at humour...
