Grey long-eared bat  (Plecotus austriacus)

In Europe, this species is widespread and fairly abundant in the south, is less common than the brown long-eared bat in central areas, and rare in the northwest (7). In Britain this species is very rare (7), and is known only from the southwest and the coasts of southern England, it also occurs in the Channel Islands and on the Isle of Wight (7). Although probably always rare, several British populations have become extinct in the last 30 years (7).

This bat has a strong preference for warm lowland areas, tending to inhabit cultivated areas and valleys below 400 metres (7). Summer roosts are in buildings, and hibernation occurs in caves, mine tunnels and cellars (2).
