Book Chapter: Statistical Principles of Post-Construction Fatality Monitoring

A book chapter written by USGS and Swiss Ornithological Institute researchers describes current statistical methods that combine data from detection probability models and observed carcass counts to provide unbiased estimates of the total number of bird or bat fatalities occurring at a wind energy facility over a specific, usually extensive, period of time. Authors first explore three major sources of imperfect detection of carcasses – carcasses landing outside the searched area, carcasses that are scavenged or removed, and carcasses missed by searchers. They also address the influence of these estimated detection parameters on the ultimate accuracy and precision of fatality estimates. They compare several different statistical approaches to combine detection probability models with observed counts to estimate fatality at wind power facilities. Lastly, authors discuss the unique issues presented when the observed carcass count is zero, which can occur when monitoring for fatalities of rare or endangered species.
