Yes, swallows are known to sleep while in flight. They can enter a state of unihemispheric slow-wave sleep, allowing one hemisphere of their brain to rest while the other remains alert for potential dangers. This adaptation helps them conserve energy and avoid predators while still being able to maintain their position in the air. However, they also rest on perches when necessary.

Swallows have a distinctive wing shape characterized by long, pointed wings that taper to a narrow tip. This aerodynamic design allows for agile flight and quick maneuverability, which is essential for catching insects in mid-air. Their wings are also relatively long and slender, contributing to their ability to glide efficiently. Overall, the swallow's wing shape is adapted for speed and agility in flight.
