IntroductionThe most aerial of birds, the common swift is renowned for its superb flying ability, favoring a life spent almost entirely on the wing. This bird is unique in its ability to stay airborne for extended periods, spending up to nine months aloft outside the breeding season. The common swift performs most activities in the air, including feeding, preening, playing, sleeping and mating and, in fact, it only lands to feed its young or roost. The common swift’s body is perfectly developed for flying. During a falling this bird falls into micro sleep.
