Eagles, specifically Bald Eagles, typically live around 20 to 30 years in the wild. The average lifespan is generally about 20 years, with some individuals reaching up to 38 years of age in the wild
. In captivity, where they are protected from natural hazards and receive consistent food and medical care, Bald Eagles can live significantly longer, sometimes reaching 40 to 50 years
. Mortality in the wild is high during the first few years, especially the first year, with many eagles not surviving to adulthood (only about 10% survive to 5 years old)
. Causes of death include human-related factors such as collisions with vehicles and power lines, poisoning from lead ammunition and environmental contaminants, as well as natural causes like disease and predation
. In summary:
- Wild lifespan: typically 20-30 years, with oldest confirmed around 38 years
- Captivity lifespan: up to 50 years or more
- High early mortality, with many not surviving past 5 years
- Main threats: human-related accidents, poisoning, disease, predation
This range applies to both Bald and Golden Eagles, which have similar lifespans in the wild and captivity
