But I remember hearing about the amazing migratory flights of some small birds where, if they traveled non-stop, they’d be going like 35mph for like two days with no breaks. So it must be working well for them.

They become pretty fat, so the energy storage outweighs the increased consumption. I can always tell when they are about to leave because they are significantly round.
