Swift and graceful fliers, Barn Swallows are long migrators, with some North American birds travelling as far south as Argentina. It is estimated that these birds will fly as much as 600 miles (1,000 kilometers) a day. They travel during the day, eating insects as they go. They can even feed their young while flying!
