Bechstein’s ‘Annex’ Roost Emergence

Bechstein\’s \’Annex\’ Roost Emergence

Serotine bats (Eptesicus serotinus) found roosting in North Wales!

For the first time we can now say that serotine bats are roosting and breeding in North Wales thanks to a radio-tracking project lead by Sam Dyer. Huge thanks are of course due to the team of dedicated volunteers who have helped throughout! Below is a video of the serotines emerging from their roost!

Neitoperek, Poland – Europe’s Largest Bat Hibernation Site

Home from Nietoperek now, and just about recovered! Another brilliant trip to help with the annual census. Over 27’000 bats were counted, this result is slightly worrying, showing a drop of almost 10’000 in numbers since 2008, this year natterer’s bats showed a 50% reduction since last year alone. Having said this, a slight increase in bechstein’s bats was recorded which was nice to see! Some phtos I took this year are shown below!

Bat Boxes Do Work!!!

Well its the start of the new summer bat season and I’ve been out checking bat boxes at the Conwy Falls near Betws-y-Coed, and amongst the usual pipistrelles I found this cluster of 11 brown long-eared bats!!! The boxes have only been up since last Autumn so who knows whats we will find over the next few years!!!
