We carried out several bat inventories in the region during the summers of 2017 and 2018. A listening route, which consists of following a standardized route with an ultrasound detection device, was carried out in order to detect and characterize the bat population in the region. Several species at risk were sought, including the Little Brown Bat and the Eastern Bat.
We also found several bat maternity wards. A maternity ward corresponds to a site used by bats to give birth and feed their young while waiting for the moment of dispersal, which takes place later in the summer. These maternities can be found in natural structures such as hollow trees or caves, but also in human habitations. In the region, the most common species is the Big Brown Bat and it is the bat that is most likely to use human habitations as a birthing or hibernation site.
Further analyzes of sonograms (recording of calls with a special device) will allow us to detect the presence of various species by relating everything to the type of habitat used.
