       | Seems the ones who live on the Japanese islands do this as

       | 
       | Like their bigger cousins they use dynamic soaring. A technique
       | for harvesting energy from the wind by up and down oscillations
       | to cover distance rather expending muscle energy flapping their
       | wings.
       | 
       | Afaik they can also lock their wings into glide mode with tendons
       | without causing muscle fatigue to maintain flight for days on
       | end.
       | 
       | Also using unihemispheric slow wave sleep aids in that as well.
