Grackles are known to live up to 22 years in the wild with an average lifespan of 17 years. This is almost unheard of in other pest bird species in North America.
The common grackle is able to eat and forage almost anywhere. They are a highly adaptable species and can create homes in a variety of different settings. Common grackles also have a very high percentage of their young that live and leave the nest in comparison to other birds. This makes the common grackle a very resilient breed.
