Various studies have been conducted that suggest that birds use the sun or stars as guides. Birds may also use the physical characteristics of the land below, following rivers, shorelines, foothills and valleys as guides. There is also the "homing" instinct that has been studied. There have been studies where birds have been taken in closed boxes to remote locations and released. The birds found their way back to their colonies.
