In short, it seems that they do what glider pilots do. Quite why it has taken centuries of nonobservation for so-called scientists to be baffled by this sensible behaviour is beyond me. 

The migration that intrigues me is the Red Admiral butterfly. Swarms of them fly from Spain to northern France or the Netherlands, then wait for a high-pressure system that will give them a steady east wind to take them to England. That isn't just a matter of taking advantage of favourable local currents ad hoc, but of serious forecasting- it's a 24-hour journey over water.
