The EM3 is a full spectrum bat detector which records high quality sound files however it is not always possible to distinguish to individual species by call alone. This is especially true of one family of bats (Myotis). In the North Pennines AONB this is likely to include Daubentons, Brant’s, Whiskered and Natterer’s bats. The records you receive will just refer to Myotis sp. unless there is sufficient evidence from the call to identify to species level.
