This little Pipistrelle Bat came in via the RSPCA! He had woken up from hibernation with some sort of hair or fibres around one wing which meant that he couldn’t stretch the wing out. As a result, he couldn’t fly and ended up on the ground where he got very cold. The fibres were removed, the little Bat was warmed up and fed before being released the following evening.
After the release, we were told about problems that are being researched regarding breathable membranes used in roofing. We were really struggling to find an explanation for the presence of these fibres and a description of how thick but hairlike they were. Sadly, we think this does explain the Bat’s predicament. A link to the research of this problem is here.
