Migration ecology of Sabine's gulls (Xena sabini) from the Canadian high arctic
Bibliographic record
Abstract
Sabine’s gulls are the only Arctic gulls that undertake trans-equatorial migrations \nbetween their breeding grounds and offshore wintering areas. I used light-based archival \ngeolocation devices (n = 36) to track Sabine’s gulls from one of their northernmost \nbreeding colonies, on Nasaruvaalik Island in the Canadian High Arctic, to their wintering \nsites in the Southern Hemisphere. I discovered that birds from Nasaruvaalik Island \nmigrate to both the Pacific and Atlantic wintering areas this species is known to use, with \nthe majority of birds migrating to a restricted area in the Humboldt Current off the coast \nof Peru and a small portion of the birds migrating to an area in the Benguela Current off \nthe coast of South Africa. I characterized the routes, timing, and distance of Pacific \nwintering Sabine's gulls. Analysis of the movements of these individuals revealed that \nSabine’s gulls exploit highly localized areas of elevated marine productivity along a \nmigration route of more than 28,000 km. I identified the Juan de Fuca Eddy off the \nsouthwest coast of Vancouver Island, British Columbia as a critically important foraging \narea during both north and southbound migration. I also describe the non-stop overland \ncrossing by some birds between the Pacific and Arctic Oceans during northbound \nmigration.

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.
