Abstract
We document the first visual observation of a Lasiurus cinereus (Hoary Bat) flying over the open ocean, 49 km from the northern California coast. This observation provides further evidence that this migratory species at times utilizes offshore habitat. Hoary Bats face significant, populationlevel threats from collisions with onshore wind turbines, particularly during late-summer and autumn migration periods. The location of this sighting within a leased offshore wind-energy area highlights the potential for Hoary Bats to be impacted by planned of fshore wind-energy development.
