Average lifespan is a stupid statistic. If 20% of the albatros die soon after birth because they get eaten by predators or whatever, this skews the average lifespan significantly. It's also why life expectancy statistics from a few centuries ago look insane - people didn't routinely die at age 30, but child mortality was high and skewed the average.
