Seems the ones who live on the Japanese islands do this as standard practice.
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.
