When darkness sets in over South West Wales out will come the pipistrelle bat, the smallest and most abundant of the bat family in Britain. Closely tied to areas of human habitation, their roosts can often be found in gaps between soft boards, panels, cladding and beneath roof tiles.
Using echo-location to find its way around, it hunts on the wing and its prey include small moths, gnats and other insects. Despite their abundance, research indicates that British populations have dropped by 70% since 1978, and so the species is part of the CCW's 'Action for Wildlife' initiative.
