In late December the count was 12 bats, the highest ever for a December count. We found six Daubenton’s bats, one Natterer’s bat M. nattereri and five brown long-eared bats.
December can be really varied, we found three bats in 2014, none in 2015 (that was a bad winter for bats…), nine in 2016, six in 2017 and nine in 2018, making this year our highest December count.
We have been surveying these sites since 2014 and on this visit a Natterer’s bat was found in the top adit (a great find, Grace), the first time we have recorded that species there, in our second most used site. It still amazes me how/why bats find this remote adit which is over 600m above sea level.
