Migration of King, Somateria spectabilis, and Common, S. mollissima v-nigra, Eiders past Point Barrow, Alaska, during spring and summer/fall 1996
Bibliographic record
Abstract
We counted migrating King (Somateria spectabilis) and Common (S. mollissima v-nigra) eiders at Point Barrow, Alaska, during spring and summer/fall 1996.During spring (1 May to 2 June), we estimated that 371 451 (95% C.1.+109 093) King and 72 606 (95% C.I. + 13 824) Common eiders passed Point Barrow eastbound.During summer/fall (10 July to 16 October), we estimated a passage of 507 667 (95% C.I.+ 84 680) King and 111 635 (95% C.I. + 42 440) Common eiders westbound.Our estimates provide evidence that both populations may have declined since 1976.Many King Eiders were observed in September and October suggesting that 1996 was a productive year.Migration counts during late fall at Point Barrow may provide a means to monitor King Eider production.King Eiders appeared at Point Barrow in early May but the peak of Common Eider migration occurred later.During summer/fall migration, most male and many female King Eiders migrated out of the Beaufort Sea to molt, whereas approximately 75% of the Common Eiders molted before migrating past Point Barrow in September and October.King Eiders comprised 85% to 90% of the identified eider migration, Common Eiders comprised most of the rest, and very small numbers of Spectacled (Somateria fischeri) and Steller's eiders (Polysticta stelleri) were seen.

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.
