This isn’t just recreational listening, mind you—this is also for science. I am a volunteer observer, one of several who are gathering data about dwindling amphibian populations in this region.
For the parcours d’écoute (“listening pathways”) project I am on, participants each choose a quiet eight-kilometre stretch of road and go out listening along it, noting the frog and toad species they hear and the volume of their calls, returning to record these observations in the same spots once more, later in the season, ideally year after year.

It’s called the Amphibian Population Monitoring Program, a long-term citizen-research project created in the 1990s by the Saint Lawrence Valley Natural History Society—part of a provincial-government push that came about when the International Union for Conservation of Nature highlighted worldwide declines of amphibian populations.
