The shaft is not down the center.  When the bird takes to the air, its wing feathers spread to create an aerodynamic surface. When the bird lands, feathers are flexible enough in their arrangement to enable the wing to fold neatly against the bird's body without bending or damaging the flight feathers.

Contour Feathers

Contour feathers give the bird its characteristic smooth round shape. They also give the bird its visual coloring and provide a first level of defense against physical objects, sunlight, wind and rain. Often in males they are colored to attract a mate, while in females they are camouflaged for protection during nesting.
