How can they fly non-stop for thousands of miles? Do they stop and take breaks?

I may be wrong but I believe this was answered recently.
I believe some birds are able to turn off half their brain at a time, in order to rest the other half. Or they can sleep for a few moments and wake for a few moments, rinse and repeat.
Their structures also allow them to stay up without using absurd amounts of energy. Their bones are hollow, and the way some birds increase their oxygen intake allows them to be much much lighter than humans. (I don’t know enough to go super detailed so hopefully someone else can)
