What is the average age of birds?

There is no one definitive answer to this question, as the average age of birds can vary depending on the species. Some species of birds, such as parrots and eagles, can live for several decades, while others, such as hummingbirds and sparrows, typically only live for a few years. According to the Cornell Lab of Ornithology, the average lifespan of a bird in North America is about 10 years.
