jA•U•y Swarth on the Birds of the Skeena River Region, B. C.--This is • report • on the results of another of the field explorations conducted by the Museum of Vertebrate Zoology of the University of California under the patronage of Miss Annie M. Alexander during the summer of 1921.The region covered lies on the east of the Coast Range, with a flora and fauna related to the interior country and similar in a general way to that of the Upper Stikine River district, already reported upon by the same author.Mr. Swarth found the fauna of the valleys to be Canadian while a well deõned IIudsonian belt was present on the mountains and the treeless p•ks showed Alpine-Arctic characteristics.We note in the portion of the report relating to the birds that the Rock Ptarmigan of the region proved to be quite distinct from Lagopus r. dixoni of the Aleutian Islands and probably represents a new sub-species.Material obtained seems to show that Dryobates p. glacialis Grinnell, of Alaska, is identical with the Rocky Mountain Downy Woodpecker D. p. homorus which however should be known by the earlier name leucurus tIartlaub.The specimens of Pigeon Hawks obtained show pretty clearly that the three forms, columbarius, suckleyi and richardsoni are all subspecies of a single species, Falco columbarius.Mr. Swarth also considers that Parus hudsonius columbianus Rhoads is a valid form, while he gives some interesting data 5n the molt of the Pipit.The report is a valuable contribution to our knowledge of the fauna of the north-west.--W.S. Sclater'a •Systema Avium Ethiopicarum.' •--The first part of this important work is before us, covering the families from the Struthionidae through the Picidae, essentially in the order adopted by A. II.Evans in the bird volume of the 'Cambridge Natural History.'The plan of treatment follows that of the A. O. U. and B. O. U. 'Check-Lists' in practically all details, a binomial group name appearing at the head of each series of subspecies, the usual generic headings, with references and type localities, etc.In addition there are foot notes referring to certain changes from current nomenclature and references to revisions of groups.The nomenclature follows the International Code as nearly as possible, but, as the author truly says, there is a certain amount of ambiguity in the application of some of the rules which leaves the correct names for certain.species still in doubt.Common names are given to all recognized forms but some of them are so cumbersome that they are little better than Latin trinomials and will 1 Birds and Mammals of the Skeena River Region of Northern British Columbia.

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.
