Prey remains from bald eagle nests on Santa Catalina Island contained almost 90% fish (Newsome etal. and C.A. A total of 44 golden eagles, including 10 eaglets born on the islands, were trapped and relocated, and monitoring indicates that none have returned. Wind has taken the most proactive and leading role of any utility-scale energy source to minimize wildlife impacts in general, and specifically for eagles, through constantly improving siting and avoidance and minimization techniques, and identifying options to offset the industry's comparatively minimal impacts. Apex predators, such as the eagle, play an important role in the balance and health of an ecosystem. 5 What is the niche of the Bald Eagle in its ecosystem? Because of this, they are our early-warning system for pressing concerns such as climate change. Unique threatened species such as the Koala and Tasmanian Devil are national icons.

Thanks to years of protection, there are now more than 4,000 pairs of bald eagles and the species is no longer threatened or endangered., About the Endangered Species Protection Program, Assessing Pesticides Under the Endangered Species Act, Endangered Species: Information For Pesticides Users, Litigation on Endangered Species and Pesticides. Although they had never bred historically on the Channel Islands, golden eagles were able to colonize the northern Channel Islands in the mid 1990s due to the presence of an alien prey base (feral pigs and mule deer fawns) and the absence of the native bald eagle, extirpated from the islands by chemical contaminants and by direct persecution.
