Survival Rates: As radio telemetry study data increase, it appears that first-year survival is better in some areas than in others, with urban eaglets not faring quite as well as those from rural areas.
Findings from some of these studies (all of which had good sample size):
- Chesapeake Bay: 100% survived from 8 weeks of age to nest departure at 10–12 weeks of age; 100% survived their first year
- Texas: 97% survived to nest departure
- Florida: 93% survived to nest departure; a minimum of 63% survived their first year
- California: 77% survived the first year
- Montana: 91% survived their first year
- Yellowstone National Park: 87% survived their first year
- Maine: minimum of 73% survived their first year
