Plus lots of animals like polar bears both put on fat and become dormant.

Blue is always getting pushed. Migratory birds become fat before the flight to have the energy requires and hibernating species do the same so they can afford to eat very little during winter.

That must be a very delicate balance since it must expend more energy to fly if the bird is heavier.
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.
