Birds age differently than humans do. Generally speaking, the age of a bird can be calculated in the following ways:
1. First is the incubation time. The time it takes to hatch a baby bird from an egg varies for different species of birds.
2. Next is the nesting period. This stage refers to the time the young bird lives in the nest and is usually the longest stage of a bird's life.
3. The last stage is the fledgling stage. This stage is when the young leave the nest but are still young, and the age at which birds reach adulthood also varies by species.
It's important to note that bird lifespans vary from species to species, with some able to live as long as decades and others living only a few years.
