Abstract
Grinnell (1909:211) described a new subspecies of the Red-tailed Hawk, Buteo jamaicensis alascensis, as “always blackest dorsally, and decidedly smaller” than a “large series” of Western Red-tailed Hawks, B. j. calurus, at that time the only subspecies of B. jamaicensis recognized in western North America. He based his description of this “Alaska Red-tailed Hawk” on four specimens collected in 1907 in southeast Alaska (Figures 1–3), two of which he designated as the type specimens. Grinnell compared the adult type, MVZ 51 (♂), with adults of calurus and found it darker dorsally, with a wider dark subterminal tail band, stronger flnk barring, and wider black shaft streaks on the belly. The other three specimens comprise a juvenile (MVZ 41), also designated as a type, and both of its parents. The latter (MVZ 42, ♀; MVZ 43, ♂) are more typical of alascensis in having the breast rufous (Figures 2 and 3). Grinnell wrote that the juvenile type specimen is also darker above and has the dark tail bands wider than those of juvenile calurus; he saw no suggestion of a dark morph in alascensis. So far as known, the range of alascensis comprises the temperate rain forests of southeast Alaska and coastal British Columbia, including the Queen Charlotte Islands (now Haida Gwaii) and western Vancouver Island (see Hellmayr and Conover 1949, Wheeler 2003).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
