Last weekend a visit to a well know site in Devon paid off with a number of species found, although all appeared to be single animals en route to their feeding grounds. Click on the name in the captions below to hear a short audio file of the echo location call.
|Lesser Horseshoe Bat Rhinolophus hipposideros|
Note the mostly flat CF call around 112 Khz
The note around 56 Khz is the harmonic note.
|Greater Horseshoe Bat Rhinolophus ferrumequinum|
Similar in shape to the Lesser Horshoe but
emitted around 84 Khz and longer in duration.
