Homing pigeon photo from Care2.com
Paula Alvarado, of Care2, reminds us that homing pigeons can return from extremely long distances (up to 2000 kms.) without any guidance. Well, not exactly. According to research by the University of Frankfurt, these pigeons have iron-containing structures in their beaks, which help them sense Earth's magnetic field, independent of their motion and posture, and thus identify their geographical position. Undoudtedly, there are reams of of scientific data to back this up but I, for one, will just accept it as one more of nature's miracles. At 69, I am still young enough to require my daily allotment of worldly wonders.
