navigation

or

orientation

a process of direction-finding. Many animals are capable of navigation particularly those performing long MIGRATIONS. Birds are now known to find their way home (see HOMING).by means of the sun and stars, in addition to landmarks. Bees, and other ARTHROPODS, use the pattern of polarized light in the sky (from which they deduce the direction of the sun) and other organisms may use chemical gradients to trace a route. For example, salmon find their specific river for breeding purposes by following a scent in from the sea.
