This report, submitted to the Scientific Review Committee (SRC) by the Monitoring Team (MT), describes the results of avian fatality monitoring of approximately 2500 wind turbines conducted at Altamont Pass Wind Resource Area (APWRA) between October 2005 and October 2007. We analyzed data from the first two years of this study to calculate average annual mortality rates and an APWRA-wide fatality estimate for all species as well as for four raptor species (golden eagle, red-tailed hawk, American kestrel, and burrowing owl) separately and combined. We then analyzed the results for inter-annual and seasonal variations. We derived these estimates using methods and criteria that make them comparable to baseline mortality estimates, provided by the SRC, that were derived from earlier studies (Smallwood and Thelander 2004).
