Several bat species can be observed in Humboldt County, including the Mexican free-tailed bat (Tadarida brasiliensis), hoary bat (Lasiurus cinereus), and big brown bat (Eptesicus fuscus). The objectives of this study were to investigate what bat species occur on campus and how variables such as artificial light, weather, and lunar phase might influence bat activity. Ultrasonic acoustic recorders were deployed on the Cal Poly Humboldt campus to capture recordings of bat vocalizations. Additional data from the Arcata Community Forest during a previous year was used to compare the detected species in the forest in Spring 2019 to the detected species on campus in Spring 2025.
