The Barbastelle (Barbastella barbastellus), also known as the Western Barbastelle, is a European bat. It has a short nose, small eyes and wide ears.

It is rare throughout its range. In Britain, only three breeding roosts are known, including Paston Great Barn in Norfolk. In Norway, it was considered extinct, having only been sighted in 1896, 1911, 1913 and 1949. However, it was again found in 2004 and 2008.[1]

[edit] Echolocation

The Barbastelle has two main call types used for echolocation. The frequency parameters of call type 1 lie between 30-38 kHz, have most energy at 33 kHz and have an average duration of 2.5 ms.[2] The frequency parameters of call type 2 lie between 29-47 kHz, have most energy at 38 kHz and have an average duration of 4.1 ms.[3][4]
