Add occurrence probability to detections

[slug56]

Hello and thanks for a great project,

I'm moving over from BirdCAGE, which offers occurrence values against detections, at least in the MQTT payloads:

BirdCAGE/record/garden

{
    "CommonName": "Common Buzzard",
    "ScientificName": "Buteo buteo",
    "ConfidenceScore": 0.9631,
    "TimeStamp": "2025-08-23 10:58:03",
    "StreamName": "garden",
    "ImportanceLevel": "record",
    "Occurrence": 0.5228373408317566
}

This is convenient for building alerting around birds considered rare for the location/time of year. For example, I might like to be alerted about a Goldcrest in my garden, but less so a Woodpigeon:

Is this value an addition that might be possible in BirdNET-Go?

This should be very easy to add, should be doable for next snapshot release.

Amazing, thanks so much. I've all but moved over to BirdNET-Go now 😺 should I expect to see occurrence values in MQTT payloads from Nightly Build 20250825? Only that they don't seem to be coming through, though the release notes suggest they should be.

Yes they should be included now, let me know if you see any issues with that

I'm on nightly-20250825-1-g3b4f4c08 and occurrence is still missing.

You are correct, there was disconnect it code which prevented value to be added to MQTT messages, this fixes it #1229. New nightly build is ongoing.
