Bird Migration

Bird Migration


Each year, with the onset of Winter, flocks of birds from the Northern hemisphere fly long distances to warmer territories in the South. Birds navigate their way by following internal compasses comprising tiny grains of a mineral called magnetite, stored in their brains. During rest stops they recalibrate their inner compasses using the positions of the stars to account for the fact that magnetic north lies 1,000 miles (1,600 kilometres) from the North Pole. When rest stops are too short, birds can get disorientated. In a similar way we possess a sense of inner knowing that helps us to find our way in life. But, unless we allow ourselves daily periods of time alone in which to tune into this inner knowing and recalibrate it against changing circumstances, we, like migrating birds, can lose our way.
