what is it?
The grey long-eared bat ( Plecotus austriacus ) is a fairly large European bat. It has distinctive ears, long and with a distinctive fold. It hunts above woodland, often by day, and mostly for moths. It is extremely similar to the more common brown long-eared bat, and was only distinguished in the 1960s, but has a paler belly.
