NOTE ON THE BirdNET MODEL (separate license)

The MIT license above covers the birdnet-rs source code only. It does NOT cover
the BirdNET machine-learning model — the model weights, the species label list,
or the eBird taxonomy data — which is a separate work under a different license:

    BirdNET GLOBAL 6K v2.4
    (c) K. Lisa Yang Center for Conservation Bioacoustics,
        Cornell Lab of Ornithology.
    Licensed under Creative Commons
        Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)
        https://creativecommons.org/licenses/by-nc-sa/4.0/
    Canonical source: https://zenodo.org/records/15050749

For convenience, birdnet-rs distributes a format-converted (TensorFlow Lite ->
ONNX) copy of this model as a GitHub release asset; the packaged builds download
it on first run. Only the serialization format was changed — no weights were
retrained or altered. The converted model remains under CC BY-NC-SA 4.0, which
means use of the model (including via birdnet-rs) is limited to NON-COMMERCIAL
purposes, requires ATTRIBUTION, and any redistribution of the model — converted
or not — must remain under CC BY-NC-SA 4.0. See the MODEL_LICENSE file shipped
alongside the model files.
