Abstract
One of many human-caused mortality factors that affect raptors is electrocution. Many raptor species perch on power poles or transmission lines, and electrocutions can occur. Electrocutions can affect endangered raptors that occur in Hokkaido, such as the Steller's sea eagle, White tailed eagle, Mountain hawk eagle, and Blakiston's fish owl in Hokkaido. It is important to increase our understanding of the reasons why some raptors are electrocuted and develop solutions to this problem. We estimate mortality due to mortality for a variety of endangered species, and examine the effectiveness of retrofitting electricity transmission infrastructure with devices that prevent electrocution. The need to reduce the threat of electrocution is urgent, and will not be achieved without the cooperation of the electricity company, wildlife biologists, government, and other stakeholders.
