Bat Surveys completed at the McEwen And Pelton Nature Reserves
During July and August this summer surveys were conducted at the McEwen and Pelton Nature Reserves to determine which species of bats are present. The only way of determining if a bat is present is by hearing them, and because human ears cannot hear their high-frequency calls, this is not an easy task.
Toby Thorne, a bat expert working with OLTA (the Ontario Land Trust Alliance), used two electronic devices, one of them lowered the pitch of the bat calls and broadcast them at frequencies people could hear, and the other recorded the actual calls that they could be analysed later.
Toby has not yet analysed the result of our surveys, but he believes that we heard mainly Big Brown Bats, and we may have recorded Hoary Bats as well. A few bats were seen at both properties, the most active location was the pond at the McEwen Nature Reserve.
Toby’s final report will be published on our website (nltrust.ca) early in 2017.
We thank the OLTA for proposing for supporting this worthwhile endeavor.
