We are now in the season of spring migratory birds flying to and from Siberia.
The flight route is the "Hokkaido Central Flyway. It is a flight route over the plains of central Hokkaido from the Yufutsu Plains in Tomakomai to the Ishikari Plain and the North Sorachi Plain.
This is a scene of graceful migratory birds flying efficiently and cooperatively with each other in a V-shape flight and out of the wind.

Energy-saving flight with as little burden as possible by utilizing the turbulence of the wingtip vortex!
