Abstract
There are many potential proximate and ultimate causes of bat fatalities at wind turbines, including: random collision with rotating blades, barotrauma (injury due to abrupt changes in barometric pressure), attraction to blade motion, attraction to modified landscape features, attraction to turbines as roost or mating sites, and attraction to insect aggregation at turbine sites. These affect the 30 species of bats known to roost, hibernate, or otherwise reside in New Mexico.
