If someone stumbling over this PR, has a RPi5 with 4G (or 8) of RAM, I'd be interested how close that hardware comes to real-time processing with the Perch 2.0 model.

[Svardsten53]

I have a RPi5 4GB running Trixie and am able to test for a couple of days.

[Nachtzuster]

@Svardsten53 Cool, it doesn't have to be days, just enough to let any thermal throttling kick in, 1/2h or so.

[Svardsten53]

How should I proceed?

[Nachtzuster]

to switch to this branch:

git remote remove origin
git remote add origin https://github.com/Nachtzuster/BirdNET-Pi.git
git fetch
./scripts/update_birdnet.sh -b more_models

Then in the ui:

• Tools->Settings->Model
  change the model to Perch and save.
• While you're in there, make sure the recording length is set to a multiple of 5s.

Then, on the View Log page, you should see it start the download & install of Perch, and start analyzing again.

To revert after the test:

• change the model & recording lenght back to what you had & save.
• run Tools->System Controls->Update

I have made the modification and it went well. It is winter and dark here and no birds are awake now, will come back tomorrow when I have real hits. The log looks like this right now:

[Nachtzuster]

@Svardsten53 Thanks! So it looks like a RPi5 can comfortably run Perch.

[Svardsten53]

Is it possible to limit the results to birds? I am now getting false positives on wolves and frogs. Is it possible to use eBird filtering?

What is the status of the new analysis model from BirdNET-Analyzer?

[dalogue1]

I am testing out the Perch_v2 model, and I notice that for my system the model returns lower confidence levels to identify the same types of birds. For instance, I had my confidence set to 0.8 originally and now I have it set to 0.3

My recordings have a background hum from an A/C unit that I cannot avoid and I suspect that is affecting the confidence.

That difference aside I am running the model and appear to be getting good results. This is my Perch 2.0 site on BirdWeather https://app.birdweather.com/stations/5355

[dalogue1]

I have been modifying the settings and what I settled on so far is as follows:

• Recording length: 33
• Extraction Length: 5
• Overlap: 1
• Minimum Confidence: 0.7

This results in the model having a better chance of having a window of 5 seconds that identifies well.

The RPi5 4GB with M.2 NVME has no problem keeping up.

With the upcoming BirdNET v3, that would probably be a good feature to have.
I'm not sure what you mean by eBird filtering - could you elaborate?

Thanks for the screenshot - So just over 2G in use, Maybe the recommendation should read 2G free RAM.

[Svardsten53]

By eBird filtering I mean the function we can currently check for the regular model at the top of the first page for settings: Species range model V2.4 - V2
It would also be good to have a choice for whether you only want birds reported or if you also want other animals. However, maybe we should wait until BirdNET V3 is released and see what possibilities there are.

Are there additional changes needed to this PR or will it be rolled into the main branch soon?

@dalogue1 see #506 we're still missing common name translations
