The mystery of how a pigeon can always find its way back home has finally been solved. Scientists believe that pigeons have a spatial map that allows them to fly in an unfamiliar territory and know exactly where they are going. The finding replaces the current theory that pigeons compare the coordinates of their location with those of the home loft and then systematically reduce the difference between the two to find their way home. This earlier theory likens the navigation of pigeons to that of flying robots. But experiments carried out at the University of Zurich have shown that pigeons possess cognitive capabilities. |
