In winter, the food transport of swallows in temperate regions is greatly reduced, so many species migrate. But unlike most other passerine migratory birds, swallows migrate during the day, are loafers and fly at low altitudes. In addition, they often forage on their migratory routes, so their net fat reserves are lower than those of other migratory birds of the same size.

Species that breed in Africa often migrate in response to rainfall patterns, but little is known about the specifics.
