Things u need to know about swallows

The name 'swallow' is a very old one, derived probably from the old English 'swell', meaning to swirl, a reference to the bird's swooping flight, or from the old Norse 'swala', meaning a cleft stick, which refers to its tail.Swallows eat mostly insects, but will also supplement their diet with berries.Swallows have adapted to hunting insects on the wing by developing a slender, streamlined body and long, pointed wings, which allow great maneuverability and endurance, as well as frequent periods of gliding.
