The barn swallow and house martin hunt for airborne insects in a manner similar to that of the slightly larger swift, and occasionally mixed groups of the species form. The most noticeable differences between the three types are:

* The shrill screaming call of the swift distinguishes itself from the more inconspicuous babbling of the swallow.
* The narrow sickle-shaped wings of the swift are longer than its body, and its silhouette in the air resembles an anchor.
* The swift's wingbeats are deep and quick, and the swift glides for longer. The swallow's flight is more fluttering, and it presses its wings further to the rear during beats.
* Although sometimes difficult to discern against a bright sky, the underside of a swift, with the exception of the white spot under its chin, is entirely dark brown. Swallows show a beige-white underside. They can also be recognized by the long forks in their tails.
