Bat Sonograms After searching the web for some example bat sonograms and failing to find a decent reference collection I've uploaded these examples. All the sonograms have been recorded using a Batbox Duet heterodyne and frequency division bat detector. Although this detector is at the 'budget' end of detectors, it still produces acceptable sonograms that can help identify the bat to species. The sonograms have been produced using Batscan software.
All sonograms have been produced during real field surveys for foraging bats. They are not sonograms of known bats from roosts. Comments to my email are welcome, more species will be uploaded when available.
