Scilly bats return after 40 years
WILDLIFE: A rare species of bat has been found breeding on the Isles of Scilly for the first time in 40 years.
A brown long-eared bat was found by University of Exeter biologist Dr Fiona Mathews and her team, a postgraduate student and the Wiltshire Bat Group.
The senior lecturer said they were “surprised and delighted” by the find of the pregnant female bat.
They found that the bats had moved to a new site.
