THE NOMINATE SUBSPECIES OF THE PURPLE FINCH IN CALIFORNIA AND WESTERN NORTH AMERICA
Bibliographic record
Abstract
THE PURPLE FINCH (HAEMORHOUS PURPUREUS) IS MOST OFTEN RECOGNIZED AS COMPRISING TWO DISTINCT SUBSPECIES: PURPUREUS, BREEDING AND WINTERING THROUGH MOST OF CANADA AND THE EASTERN UNITED STATES, AND CALIFORNICUS, REPORTED TO BE LARGELY RESIDENT ALONG THE PACIFIC COAST, FROM BRITISH COLUMBIA TO SOUTHERN CALIFORNIA. ALTHOUGH THE MIGRATORY PURPUREUS IS THE SUBSPECIES EXPECTED AS A VAGRANT IN ALASKA AND THE INTERIOR WEST, THE IDENTITY OF THE SUBSPECIES OCCURRING IN THESE REGIONS HAS BEEN POORLY DOCUMENTED. HERE WE DOCUMENT THE FIRST RECORDS OF PURPUREUS FOR CALIFORNIA AND ASSESS THE SUBSPECIES OF THE PURPLE FINCH FROM PHOTOGRAPHS AND SPECIMENS THROUGHOUT WESTERN NORTH AMERICA. NOMINATE PURPUREUS OCCURS REGULARLY IN THE WESTERN GREAT PLAINS STATES AND VERY SPARSELY FARTHER WEST. H. P. CALIFORNICUS MAY BE MORE PRONE TO VAGRANCY THAN PREVIOUSLY SUSPECTED, AS WE DOCUMENT THE FIRST RECORDS FOR ALASKA, COLORADO, AND NEW MEXICO.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
