Summary ²

The Common Swift (Apus apus) 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.
