The 2nd Annual Culvert Blitz was held the weekend of January 5-7. Participants included biologists and volunteers from across the state who inspected culverts for the presence of roosting bats. In stark contrast to the unseasonably warm temperatures during last year’s survey, this year’s culvert blitz was marked by cold, icy conditions. The results of the survey were exciting, as the MBWG completed 15 routes in the three-day survey period, checking a total of 234 culverts. Over 3,000 bats were documented using the culverts, including tricolored bats (Perimyotis subflavus), Southeastern myotis (Myotis austroriparius), big brown bats (Eptesicus fuscus), Rafinesque’s big-eared bats (Corynorhinus rafinesquii), and Brazilian free-tailed bats (Tadarida brasiliensis).
In addition to bat use, surveyors recorded environmental data including air temperature, culvert dimensions, adjacent habitat classification, substrate type, and other characteristics.
