The Barn Swallow, Hirundo rustica, is an uncommon visitor to parts of northern Australia. It can be distinguished from the Welcome Swallow by its black breast band and white underparts. Other swallow species include the White-backed Swallow, Cheramoeca leucosternnus, which has a white back and grey white head, and the Red-rumped Swallow, H. daurica, which is a rare visitor to Australia's north and has a red rump and streaked, chestnut underparts. Swallows are also confused with the martins, of which there are two species in Australia: the Fairy Martin, H. ariel, and the Tree Martin, H. nigricans. Both species have shorter, more square tails, and white to buff rumps.
Swifts (Family Apodidae) are similar in habits and appearance to the swallows, but have longer and more curved wings and differences in their flight. Swifts are rarely seen landing, while swallows are a common sight on wires, posts and other suitable perches.
