The barn swallows wintering in southern Africa are from across Eurasia to at least 91°E, [21] and have been recorded as covering up to 11,660 km (7,250 mi) on their annual migration. [22] The nominate European subspecies was the first to have its genome sequenced and published.

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 western house martin is similar in habits to other aerial insectivores, including other swallows and martins and the unrelated swifts, and catches insects in flight. [9] In the breeding areas, flies and aphids make up much of the diet, and in Europe, the house martin takes a larger proportion of aphids and small flies than the barn swallow. [9]
