ONNX metadata identifies Ultralytics 8.2.67, trained on coco.yaml,
and the AGPL-3.0 License. No bird-species fine-tuning is claimed for it.

BIRD SPECIES CLASSIFIER
https://huggingface.co/chriamue/bird-species-classifier
Model card declares MIT; model architecture EfficientNet-B2.
Model graph modified for WebAssembly compatibility: final oversized
AveragePool replaced by equivalent GlobalAveragePool; learned parameters
unchanged. Native ONNX Runtime parity checked. The modified graph is split
into two static files. Reproduction script provided in source.zip.
Training source: https://huggingface.co/chriamue/bird-species-classifier/blob/main/train.py
Processor: https://huggingface.co/chriamue/bird-species-classifier/blob/main/preprocessor_config.json
Dataset: https://huggingface.co/datasets/chriamue/bird-species-dataset
The model card's dataset evaluation is not a field accuracy guarantee.
Model availability or model-card licensing is not a legal audit of training data.

FIELD NOTES
Field notes are concise original summaries of standard identification traits.
Each species dialog links its Chinese Wikipedia page for cross-checking.
Scientific names and common-name mappings need review as taxonomy changes.
