If a penguin can survive its infancy and its first years of life, it has a pretty good chance of living a fairly long life. Many penguin biologists have banded thousands and thousands of penguins and then followed which ones come to the colonies year after year. This is how we can guess at the average age of a penguin. The oldest known Adelie penguin living in the wild was 20 years old, and the big Emperor Penguins might live to as long as 50 years. If an Adelie penguin begins to breed early, say at 3 or 4 years of age, it is less likely to live to be 15 or 20 years old than if it waits until it is 7 or 8 years old to breed for the first time.
