One theory has to do with the way birds process oxygen and the proteins associated with metabolism. The result is a near impossibility to determining the age of a bird. It is also unlikely to locate a banded bird so they are hard to track. The problem is that we might not know the age of the bird at the time of banding. The banding on a bird allows us to track the age of a bird when they are spotted at a later time. What we do know about the age of birds comes from bird banding. Let’s dive into how biologists determine the age of birds and examine the oldest birds of all time. They don’t get grey hairs, arthritis, or other tell-tale signs of age.
Birds don’t show their age in the way one might expect. When we talk about the age of a bird, it is a little more complex than you might think.
Talking about age is taboo in some circles.
