Gone with the wind: Migratory birds need less time to travel along longer routes when they optimize for wind support

21 octubre 2015

Each year migratory birds travel over thousands of kilometers.

To do so, however, it seems that the shortest route does not necessarily grant the fastest journey. Birds can save energy and time if they use wind support.
