Why this species, before any model.

Of the animals whose voices we have any business asking models to map, the American crow (Corvus brachyrhynchos) is one of the strongest candidates. A brain-to-body ratio comparable to great apes. Documented tool use. Individual recognition of human faces across years. Cooperative family groups that hold territories, share food, and pass behavior down generations.

And a repertoire dense enough to warrant a map. Decades of work before ALP gave us six or eight named call types and a hunch that there was more. The new methods are recovering the "more" — graded variation, individual signature, dialect, hints of composition — visible at once on the same shared geometry.
