Preferred avian prey includes grebes, alcids, ducks, gulls, coots, egrets, and geese. It also eats dead animals (carrion). Studies of the life cycle impacts of the six major energy generation sources have shown wind energy has the lowest environmental impact of any form of electricity generation, as it emits no air or water pollution, uses no water in the generation of electricity and creates no hazardous or radioactive waste requiring permanent storage. While unfortunate, eagle losses at modern wind farms are a rare and random event, with only a few bald eagles having ever been observed to have died in collisions with a wind turbine.

Golden eagles invest much time and effort in bringing up their young; once able to hunt on their own, most golden eagles survive many years, but mortality even among first-born nestlings is much higher, in particular in the first weeks after hatching. Northern eagles are migratory,while southern birds are resident, remaining on their breeding territory all year. What is the point of saving the Philippine Eagle and other endangered species?
