To collect much needed data to better understand the bat species which call Guelph home, we have established a project on iNaturalist, to collate and add sightings of bats from the City of Guelph. To collect the data, we are planning to survey a number of sites across Guelph in the summer and fall of 2020, using the smartphone acoustic device 'Echo Meter Touch 2' from Wildlife Acoustics. This device enables us to detect, record and identify bat species using the associated phone app.
