Winter Wonders

Two members spent a day during the festive break in the Dovedale area of the White Peak inspecting various caves for hibernating bats. One cave which is a known bat roost in the summer contained a brown long-eared and a Natterer's, the latter species having never been recorded at this site & hibernating bats also never recorded before. A mine adit never inspected for bats before contained a brown long-eared hanging from the roof due to the low number of crevices.
There are several hibernation surveys planned for the coming weeks so keep an eye on our news pages for updates.

Halloween Event October 2016

Thank you to those DBCG members who helped out with the Elvaston Castle Eerie Adventures Halloween event on 30th October 2016. Dead bats and bat poo were well received by the general public.
From my experience of manning stalls at family events excited children tend to want to touch and see bats rather than look at literature. If you have a prop that you think would make a good exhibit for the stand please contact a member of the committee.

Springwood Bat Box Check

On Easter Sunday 15 members met to check the 30 tanglewood-wedge style boxes on this Derbyshire Wildlife Trust Reserve. The scheme is now 23 years old and some of the original boxes are still going.
We found 34 bats - 3 noctules and 31 soprano pipistrelles. Half of the boxes had evidence of being used since the last check at 32% were occupied on the day.

Social Media Workshop

On Saturday 13th February 2016 Joe Nunez-Mino, Director of Communications & Fundraising at the Bat Conservation Trust came up to Derbyshire to give a workshop on Social Media. 12 members bought their smartphones and tablets to the Derbyshire Eco Centre where they learnt what social media was and why they should be using it.
Several members set up Twitter accounts and as a result of the workshop, the Staffordshire and South-East Staffordshire bat groups now have Twitter accounts! One member even made social media cupcakes!

NBMP Hibernation Survey

Several members met at the Ticknall Limeyards on Sunday 7th February 2016. They were there to survey the underground features around the limeyards to survey for hibernating bats as part of the National Bat Monitoring Programme. Several tunnels, dripping wells and lime kilns were inspected but due to the warm weather just a single bat was found hibernating. However several bat boxes were also inspected which had been erected the previous year and 50% of these had evidence of bats including several hibernating pipistrelles.

31st October 2015 - Halloween at Elvaston Castle

Four members took the bat group stand to Elvaston Castle to spread the good word about bats at their Halloween event. The stand was really popular with the visiting families with children getting involved in making batty objects and learning about bats in general. Thanks to Marian, Ian, Helen & Ean for manning the stand and making it so successful.

29th September - Group reaches caving community

On the last weekend of September, DBCG had its inaugral visit to Hidden Earth, the UK's National Caving Conference. Member's Jess & Steve each gave a lecture on the Saturday morning on bats underground and our autumn swarming project.
Both talks recieved lots of questions and raised several discussions about bats underground. We disseminated some of the results from the current dataset.
We also had a bat group stand present at the event with lots of free information available for the 300 or so caving delegates at the event including bat cookies baked by Jess!

20th June 2015 – NBMP Roost Surveys underway

Bat group members have begun undertaking their summer surveys of bat maternity roosts for the Bat Conservation Trust's National Bat Monitoring Programme (NBMP).
We undertake surveys of several different roosts, the exact number depends on how much spare time our volunteers can give, sometimes we alternate roost counts each year. One of our longest-studied sites, Baslow Church, had its first count last Friday with 143 Daubenton's bats emerging.

30th May 2015 – Derbyshire hosts West Midlands

Did you know that only the two Midlands regions still hold regional meetings for the bat groups within those two areas? Once upon a time all regions did but they sadly have died out over the years.
Derbyshire resides within the East Midlands. However historically we were once part of the West Midlands and our strong ties with Staffordshire bat group means that we attend both East and West Midlands bat group meetings.
For the first time ever, we hosted the West Midlands bat group meeting at Calke Abbey. We're right at the top of the region but we compensated this with a chance for attendees to see serotine bats, a rarity within the Midlands.
BrumBats brought along an impressive bat cake and we spent the evening watching the three 'big' bats - noctules, serotines and Leisler's. Thanks to Simon Worledge for the photos.

12th May 2015 – Roost Count

On 12th May several members attended a roost emergence count of our Leisler's roost which has taken up residence in one of our bat boxes. Watch the video from the event below.

9th May 2015 – Further Research

One of our study sites for our autumn swarming project is a cave that is well-known and used by the caving community. Last year we found lots of bats were using the site for autumn swarming and so we wanted to understand what the underground system was like and understand why it is so popular with bats.
Caver and bat group member Jess took a couple of us inside to explore the system and we unexpectedly found 6 bats (lone males waiting for the mating season). The three bats below are all whiskered bats.
