Abstract
Many marine birds undertake long migrations between breeding and wintering areas, including some species that undertake long‐distance east–west or west–east movements across many degrees of longitude. To date, however, no east–west migrations have been described across the North Pacific. Geolocators were deployed on Ancient Murrelets Synthliboramphus antiquus breeding in Haida Gwaii, British Columbia, in 2013 and four were retrieved the following year. Longitude positions showed that all four moved rapidly westwards after breeding, three of them reaching waters between Japan and China by November and this location was also supported by ringing data. Return migration was rapid, beginning in February and reaching Haida Gwaii in March, providing the first evidence for bird migration spanning the entire width of the North Pacific. This is the longest migration recorded in any of the Alcidae.

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 it
