AI interpretation · Exceptional
This is the cluster of the unusual. Atypical calls, rare vocalizations, anything the model places but the named categories can't account for. It's where future repertoire expansion lives — the dialect variants we haven't named yet, the bridge sounds between known clusters, the calls that don't fit because the categories themselves are too coarse. Our one exemplar is exactly what the name promises: an atypical, lone-bird call from Jongsma's catalog that he himself flagged as rather atypical. The AI agrees. Whether this cluster splits into named sub-clusters, or stays as the formal home for outliers, depends on how the corpus grows.
