ABSTRACT: Echolocation signals were recently recorded at the Mackinac Island school grounds to monitor local bat activity using a Wildlife Acoustics detection meter. Seven of nine bat species native to Michigan were identified using Kaleidoscope software to interpret recorded signals. Some signals are difficult for the software to precisely identify, therefore the number of signals recorded is more a qualified than a quantified value. Software interpretations of bat calls during this monitoring period resulted in about 70% of the signals being from the Little Brown Bat (Myotis lucifugus) and 20% of the signals being from the Eastern red bat (Lasiurus borealis). Silver-haired bats (Lasionycteris noctivagans) accounted for about 3% of the detections.
