Restlessness will beset us all–a need to move, to get out, to run away, or to walk toward. These times of unease can redefine us or reground us in what we already know to be true.
We may find ourselves moving away from home and the only things that are familiar. We may trudge through the wilderness of our lives in hopes of finding something new and reassuring. We may find ourselves far away and in need of making the long journey home, forever changed with the layers of life that cling to our skin.
In these moments, there is a deep sense of longing for something mysteriously on the fringes of our lives. Those who move, whether it be backward or forward, home or away, should find relief in their willingness to explore the surroundings of their being. For this willingness is one giant part of what makes you, You.
Birds too have these moments of restlessness; and a bird’s restlessness is called zugunruhe. Like a tree’s leaves, a bird’s sense of belonging changes with the seasons. When the time comes each Spring and Fall, migratory birds head North and South, respectively.
Zugunruhe refers specifically to migratory restlessness. It is a mysterious quality that reveals itself only during migratory periods. During these times, migratory birds are known to be particularly restive–ready for the right wind or weather to make their long flight to their seasonal homes.
For a long time, humans have marveled at the mysteries of migration. But diligent research is starting to answer most of our questions. For example:
Migratory birds are able to orient themselves in many different ways. Research has shown that birds have an incredible skill set for navigation.
Birds can read the magnetic fields of the Earth to navigate the globe.
Birds can orient themselves using the sun. Diurnal songbirds, such as warblers, prefer to navigate at night and can use the stars to navigate.
Birds who have traveled the path before can use landmarks, such as mountains or the coastline, to find their way either North or South.
Even first-year migratory birds display signs of zugunruhe. A first-year bird that is caged will leave its perch and flutter in the exact direction that it needs to fly toward. This suggests that zugunruhe is something innate within each individual bird–a deep knowledge of the need to go and the exact direction it needs to follow.
Migratory birds display zugunruhe for the duration it would take to actually fly to their intended destination. If it takes two weeks for a specific specie to get to its winter home, a caged bird of the same specie will show signs of zugunruhe for two weeks. It’s as if the birds know the exact time they’re supposed to start and end their long journeys.
Reflecting on zugunruhe I cannot help but relate the idea to the human experience. Is the restlessness within us all some sort of innate impulse? Is it driving us toward something or somewhere specific? How come it pushes some further away from home than others?
Perhaps there is something to be learned from the mysteries of migration. Something very human. Something that expounds on an individual’s need to move and adapt. Something only the birds really know.
