Last year I took part in the Nathusius’ Pipistrelle survey at Draycote Water and we were lucky enough to record the species several times along the N shore around Lincroft Point. Some boxes were put up along the N shore this summer and I had high hopes of getting to see Nathusius’ in the hand when a check was made on 18/09. A few Soprano Pipistrelles were the only bats we found in the boxes but Dr. Jon Russ, Tricia Scott and I did an impromptu survey after the check. We were surprised at how little bat activity there was though we did hear an interesting Myotis and decided to leave but to hold our bat detectors out of the car windows as we drove round. In Rainbow Corner we had contacts with at least three Nathusis’ Pipistrelles and it was great to be able to listen to them for protracted periods and get used to the sound. Brown Long-eared Bat, Common Pipistrelle and Noctule were also recorded.
Nathusius’ Pipistrelle is migratory with large numbers of animals from Eastern Europe moving to the west for the winter period. It is now known that the species migrates in to the UK but it has also been recorded breeding here. There is much to learn about Nathusius’ Pipistrele in the UK but an excellent overview is presented here http://www.nathusius.org.uk/index.htm. There have now been several records of Nathusius’ Pipistrelle at Draycote Water in autumn but it has not been recorded during summer bat walks which may suggest it is a winter migrant here.
