The AWWIC (American Wind Wildlife Information Center) database is the most comprehensive database of post-construction fatality monitoring data from U.S. wind projects, incorporating both publicly available and contributed data. The 2nd edition AWWI Technical Report, Summary of Bird Fatality Monitoring Data Contained in AWWIC, summarizes bird fatality rate and fatality incident data from wind energy facilities in the U.S. and ensure the most up-to-date fatality data are available for generating hypotheses about bird collision risk at wind energy facilities.
