Barn Swallow

Barn Swallow

Barn swallows have an average lifespan of 4 years and those with longer, more symmetrical tails tend to live longer.

The average lifespan of barn swallows is 4 years. Barn swallows of 8 years of age have been documented, but these are considered the exception.

Survival prospects and longevity appear to increase with tail length and wing and tail symmetry.
