Nathusius’ pipistrelle Project 2015

The most recent postings appear at the top of the page.

2nd August 2015 - Trapping continues

Now that female bats have given birth, we've started trapping bats again in the hope of trapping a Nathusius' pipistrelle. Derbyshire project leader Bill has been out twice a week for the past couple of weeks and last night was at Carsington Water. 5 soprano pipistrelles (below) and 2 whiskered bats were caught.

June 2015 - Trapping on hold

Female bats are currently giving birth and so trapping nation-wide has been put on hold for a few weeks until the risk of catching lactating females drops. We're expecting trapping to start up again in late July. If you're a member, keep your eye on the member's calendar for new dates.

28th May 2015 - 10 bat catch

Four members went to Carsington water (the main study site this year for Derbyshire) and caught 10 bats: 7 soprano pipistrelles, 2 common pipistrelles and 1 whiskered. Given that temperatures dropped to 5.2°C this was a good catch.

22nd May 2015 - The Pna surveys 2015 are underway!

We undertook the first Nathusius' pipistrelle (Pipistrellus nathusii) survey at Drakelow nature reserve on Friday. A mild but windy evening and the two harp traps didn't catch any bats at all. Plenty of activity down on the river so better luck next time.

May 2015 - Nathusius' pipistrelle Pilot Project

The Nathusius’ pipistrelle survey is a continuation of last year's pilot study. It is being co-ordinated by the Bat Conservation Trust (BCT) and is a result of the National Nathusius’ pipistrelle conference which took place near Bristol in 2013.

Bat Groups involved include Kent Bat Group, Surrey Bat Group, South Lancashire Bat Group, Northumbria Bat Group and a joint venture by Derbyshire and Nottinghamshire Bat Groups.

The survey is following a set methodology using 2 x harp traps and acoustic lures at 4 sites per county with (ideally) a survey at each of the main sites once a month through the summer. Any Nathusius’ pipistrelles caught are to be processed in a set way including taking fur clippings and attaching a forearm ring. The fur clip is to be sent for stable isotope analysis to see if that method can shed light on if the bat is a migrant or if it is part of a resident population. We will also be fur sampling a selection of common or soprano pips caught.
As its a joint venture by our groups that means we will have 2 main sites each but will be looking at trying to trap at other sites as time allows.
Each group have 2 sets of harp traps and acoustic lures plus all the ancillary equipment needed.
BCT want the main sites to be where we have already had at least one positive Nathusius’ record and following last year's survey work our two main study sites are Carsington water and Drakelow nature reserve.
