Which bird sleeps eats and mates in the air?

The common swift (Apus apus) is a bird known for sleeping, eating, and mating while in flight. These birds are highly adapted to aerial life, spending most of their time airborne and only landing to nest. They can consume insects and drink water while flying, making them one of the most aerially active birds. Their remarkable flight capabilities allow them to thrive in their environment without needing to frequently touch down.
