The story so far!
I started looking for bats about 7 years ago. Armed with a fairly basic heterodyne Bat Detector I soon started to pick up the commonest species around Milton Keynes (Common Pipistrelle, Soprano Pipistrelle and Noctule, plus the occasional Natterer's and Daubenton's).
I then joined up with the North Bucks Bat group, and took part in some organised surveys before moving to my present house in Hampshire. Nowadays, I have a much better detector (a Pettersson D230 frequency division detector) which lets me listen to the heterodyne signal in one ear whilst recording Frequency division in my other ear (and to a recorder for further analysis).
My samples of the typical echolocation of some UK species are below together with sonograms, and power spectrums:
Common Pipistrelle
Soprano Pipistrelle
Nathusius' Pipistrelle
Barbastelle
Serotine
Noctule
Whiskered/Brandt's
Brown Long Eared Bat, Natterer's and Daubenten's to be added.
Plus some more exotic bats from around Europe:
Greater Horseshoe (Sierra Morena Spain, although this bat also occurs in the UK)
Leisler's Bat (Madeira, although this bat also occurs in the UK)
Madeiran Pipistrelle (In, yep, Madeira)
Kuhl's Pipistrelle (Sierra Morena)
Also seen, but with no recordings: Schreiber's Bat, Lesser Horseshoe, and Greater Mouse-eared Bat, plus a Pipistrelle sp. in Fuerteventura
