At 0830 h on 3 September 2010, a male and a female eastern red bat (Lasiurus borealis) were found dead on the ground at a wind-energy facility in Somerset County, Pennsylvania. The bats were discovered in an open gravel parking lot, 6 m from the Operations and Management building and 130 m from the nearest wind turbine. The building was located in open grassland, on a high ridgeline (ca. 900 m ASL) in the Appalachian Mountains. The carcasses were fresh and had no obvious signs of injury (e.g., broken limbs, blood). The pair was clasped together, venter to venter, in what appeared to be a copulatory position (Fig. 1). The male’s uropatagium was curled around the posterior of the female, and his jaws were locked onto the fur of her lower chest. We did not have a collection permit, so the bats were not handled or removed for further examination. As such, the cause of death could not be determined, and it could not be verified whether intercourse had occurred.
