Paul O'Brien is in Ontario with Jeff Bowman (OMNERF and Trent University) chasing flying squirrels and working on questions about reinforcement in the northern and southern flying squirrel hybrid zone. This is the first capture of his MSc. Following the recent Kohler, et al. paper (Ultraviolet fluorescence discovered in New World flying squirrels (Glaucomys). Journal of Mammalogy 2019) he had look for florescence. The photos are super cool!
