This is incredible! I had no idea this software existed. I’m already thinking about reviving an old Raspberry Pi 3 I have lying around for this.
Do you have yours running 24/7? Do you use a water proof enclosure for the setup?
A community for people who like birds, birdwatching and birding in general!
Feel free to share your photos and other birding-related content here. If a photo you post isn't yours, please credit the original creator! Additionally, it would be appreciated if the location of the sighting and a date were given when a photo or question is posted. You do not have to give the precise location, something like "Northern Idaho, June 2023" or even "North-Western US, June 2023" suffices.

I only set it up today, so it hasn't even been 24 hours yet, but 24/7 is the plan!
We haven't bothered with water proofing as it's set up on the back deck of my house, which is under a roof. We do have a plastic case for the Pi though, just to protect it from incidental environmental issues, but it's by no means water sealed.
Just because it outputs a value doesn't mean it's correct. It is more likely it just spits out random nonsense on a regular basis.
Bird call ID is something that dedicated software excels at. They’re basically the perfect subject for it, since many bird species have calls that are very distinct on a spectrogram like the one in the OP. Examining the patterns in spectrograms manually is a method ornithologists have been using to identify birds since the 1950s.
You will occasionally get false positives from software, but if you’re keeping the audio it can be double checked fairly easily for anything results that seem ludicrous. It works well enough that the Cornell Lab of Ornithology has made it as easy as possible to migrate your data from their bird sound ID app directly to ebird for use in scientific studies.
This uses the same detection model as the whoBIRD android app. I've used it in a side by side test with Merlin and they do not give consistent results. They're in the same ball park, but really every detection (for both apps) should be verified with human ears. And I'm not sure that's possible with a 24/7 setup.
IT'S STILL AWESOME AND FUN! I hope the talented people that made this continue to develop it. I'm glad this was posted, but like OP said, not super practical.
I found both whoBIRD and Birdnet-Pi to give good results, as long as you dismiss the low confidence results. For results with a confidence of 80 % or higher I very rarely have incorrect results. Every once in a while it confuses one kind of thrush with another, but they do sound similar to my human ears as well.
In two days, I've had one incorrect ID, and one that may or may not be accurate.
Both resolved by increasing the certainty threshold from its default of 70%, up to 80%.
This sounds cool. I might look into setting something up like this at some point
It's really cool! Not much practical use for anything, but it makes the bird nerd in me happy :)
Love this! Thanks for posting!
For those of us without the skill or kit (me!), Cornell Labs Merlin Bird ID can do the live identification part in quite a pleasing manner on an Android phone. However, the logging and kit that is practical to leave running for 24 hours is probably beyond it.
To OP, I'd have thought better mikes would allow identification of quieter calls, and be better at avoiding misidentifying non-bird noise, so might still have value.

I'll get back to you when I've got enough data to compare a cheap mic with a good mic
I installed BirdNet-PI on an unused Pi 4 that I had last month. It's so cool, and I'm surprised to see some of the birds that it captures.
I really need to get a better mic placement, though. I've got my Pi set up behind my kitchen window (inside) and the mic (a small lavaliere mike) taped behind the mesh screen.
It's not capturing nearly as much as I'd like, say, if it were in my backyard.
I will say, though, that detection on BirdNet-Pi takes some time. When you compare it to something like the Merlin app with Sound ID, which has instant detection in real-time, it's a different beast.
Just a tip. Double check the identification algorithm. Mine defaulted to the older, less accurate model. Things improved a lot once I changed it over!
What microphone are you using for this?
Just a re-purposed desktop USB mic at the moment. But I've been told that it works fine with the cheapest crappiest USB mics you can find, so I've ordered a couple of those, and will take the desktop mic back inside once I've got them setup
Cool, I might buy a mic and try this!
Wow, very cool.
You have a link to the software?
Thanks!
