How does a bird that lands is equal to death survive and reproduce?
Swifts, a bird that has been flying most of their lives, may fly even in predation, courtship, mating, and even rest, and if they land, it could mean death.
They have a special skill, "hemi-brain slow-wave sleep", which simply allows the left and right brains to rotate sleep.
At the same time, they eat, drink and rest in the air.
Why can't they stop, because they take off by gliding high, and if they fall to the ground, there is no external force to help them, so that it is difficult for them to take off, and they can only crawl clumsily and the ground, either to be eaten by predators, or to be starved to death.
