Movements and survival of bald eagles banded in the Greater Yellowstone Ecosystem

Article Abstract:

There has been little research on the movements of bald eagles after they are a year old, so a study has followed eagles from the Greater Yellowstone Ecosystem. Power lines were the most common cause of death, accounting for 20% of deaths, followed by poisoning, accounting for 14%. The bald eagles most affected are those aged between 3-years-old and 4-years-old. Bald eagles often wandered away from their natal sites during the summer. The Yellowstone National Park provides a secure habitat and helps to boost survival rates for bald eagles.
