The Common Swift is a small bird, superficially similar to the barn swallow or house martin. It is, however, completely unrelated to those passerine species, since swifts are in the separate order Apodiformes. The resemblances between the groups are due to convergent evolution reflecting similar life styles. The scientific name comes from the Greek , apous, meaning "without feet". These birds have very short legs which they use only for clinging to vertical surfaces. They never settle voluntarily on the ground. Like swallows, Common Swifts are migratory, and in midsummer they are found in Great Britain and northern Europe, while they winter much further south in southern Africa.
