Effects of weather on avian migration at proposed ridgeline wind energy sites

摘要: ABSTRACT With the popularity of wind energy increasing globally, concerns surfaced in 1980s as to potential adverse effects turbines on migrating birds. Understanding how weather conditions influence passage rates can help determine for increased avian-turbine collisions. Using vertical and horizontal mounted marine radars, raptor stand watch observations, portable handheld stations, we studied temperature, cloud cover, barometric pressure, direction, speed affected avian height migrants over 3 ridges (Wartenbe, North Dokie, South Dokie) being developed northern British Columbia. an Akaike's Information Criterion (AIC), determined that a reduced model combining speed, cover was best at explaining predicting higher (expressed no. birds/hr) fall migration both diurnal nocturnal migrants. Wind proved most important p...
