Got a new setup of BattyBirdNET-Pi or similar? Want to share tips? This is the place!

Lesser Horseshoe bat live from one of their last roosts in Germany!

I have been partnering with people from The LBV in Bavaria to setup a BattyBirdNET-Pi near a roost of Lesser Horseshoe bats that they take care of. A very cool experience with very cool people protecting very cool bats.

The live-stream is not yet public, but there is already more than 30GB audio data and bat activity data. Includes mother/pup social calls. Running at 384kHz 24/7 on a Pi 5 and usb audiomoth.

Want to see them live? Here is their camera stream:

And the live audio analysis? Running. Live sound via the cam feed - in progress.

A lot of 'day-flying' bats? The spectrogram shows a regular pulse maybe triggering false detection?

I was about to ask a separate question but your image illustrates the same problem - why does the 'pi chart' have a gap between 22:30 and 23:30? I see exactly the same...looking in the database there are many detections between 22:30 and 23:30.

Hi @Inachis ,
the mic is placed in a rooftop that is a roost. On average, that is their call activity. Also during the day. They hang about and also chirp when cleaning themselves etc.
The line does not trigger the classifier - it is in the noise set and ignored.
The gap is an artifact that comes from the binning algorithm. Can be fixed.

Hi Richard,
Thanks for clarifying the daytime activity.

Cheers,

Kelvin, do I remember correctly about the canal? Are you still interested in recording there? The system has come a long way.

Yes, Richard, canal monitoring still in plan but getting to a mobile setup is taking longer than I'd hoped; also have yet to source another suitable ultrasonic microphone.
