Welcome swallows are good indicators of temperature, as the temperature drops lower, the less likely a swallow will be observed in the South. When swallows are around, the temperature usually does not drop below -2/-3 degree Celsius. [7] Migration may occur during non-breeding seasons for larger more reliable food sources.
The house martins are closely related to other swallows that build mud nests, particularly the Hirundo barn swallows. They breed only in Europe, Asia and the mountains of North Africa. Three species, the common, Siberian and Asian house martins, migrate south in winter, while the Nepal house martin is resident in the Himalayas year-round.
Older males typically migrate first and leave the overwintering sites in late December or early January, followed by older females. Younger birds (first yearlings) typically arrive at the breeding grounds up to two months later. [19] Fall migration is also staggered, as birds head south when the breeding season is over.

The common swift (Apus apus) is a medium-sized bird, superficially similar to the barn swallow or house martin but somewhat larger, though not stemming from those passerine species, being in the order Apodiformes. The resemblances between the groups are due to convergent evolution, reflecting similar contextual development.
