Barn Swallow

Barn Swallow

Because of its extremely large range and population size, the barn swallow is evaluated as “Least Concern” on the IUCN Red List of Threatened Species.

The barn swallow has an extremely large range, and is not endangered, although there may be local population declines due to specific threats. The barn swallow does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 kilometers squared combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation).

Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations).

The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (10% in ten years or three generations, or with a specified population structure).

For these reasons the species is evaluated as Least Concern on the International Union for Conservation of Nature and Natural Resources (IUCN) Red List of Threatened Species.
