In 2015, the oldest documented wild bald eagle was discovered in the State of Washington, reaching a minimum age of 38 years. While the average lifespan of bald eagles in the wild is typically around 15-20 years, there have been instances of individuals living longer. In captivity, the record for the oldest known bald eagle goes to a female named “Grandma” who lived for at least 48 years and resided at the San Francisco Zoo.

It is important to note that bald eagles are protected by both the Bald and Golden Eagle Protection Act and the Migratory Bird Treaty Act. These legislations safeguard their well-being and contribute to their conservation. Over the past few decades, concerted conservation efforts have led to the resurgence of bald eagle populations, marking a significant recovery for this majestic species.
