While the navigational skills of birds remain largely unexplained, the theory that they use the magnetic field of the earth to some degree to map their positions is generally accepted. The magnetic field of the earth is weakest at the equator, becoming stronger toward the north and south poles. This change in magnetic strength may give birds an estimate of their latitude while in flight. This amazing ability to navigate is especially evident in homing pigeons which are able to find their way home over distances of as much as 1,100 miles…
