Bat Walk and Talk

As part of LEAF Open Farm Sunday 2013 Overbury Farms invited tenant David Worley to give an insightful talk and walk on British Bats.

 

 

The evening was open to tenants and villagers of Overbury and Conderton. We met at the Village Hall for refreshments before enjoying a very informative talk from David and his colleague Michelle from the Gloucestershire Bat Group

Bats are the only mammals that can fly. A bats wing has very similar bones to the hand and arm of a human, with skin stretched between the very long finger bones and the body to form the wing membrane. After learning about the 17 species of bat that live within the UK, their hibernation patterns and feeding habits, David proceeded to explain how we can tell the difference between some of the more common ones:

Armed with our 'Bat Detectors' we set off at about 10pm to the Churchyard where we heard a Pipistrelle at 45 kHz. We proceeded down one of the footpaths and caught a glimpse of the first Lesser Horseshoe of the night at 110 kHz. Our final stop was a pond on the Estate where David helped us to spot a Daubenton at 55 kHz.

Feeling rather satisfied we left our newly found friends in peace to head home, all of us understanding a little more about our nocturnal neighbours.
