Calidris subruficollis
Bibliographic record
Abstract
Calidris subruficollis (MGT): breeds in the central and western Arctic and migrates from late July to mid-September to wintering areas in the Southern Hemisphere, which are located mainly in the Pampas in Argentina and Uruguay. In general, it flies non-stop through inland North America and coastal Canadian provinces, crosses the Gulf of Mexico and flies as far as northern South America. It moves inside the continent and has wintering areas in southeastern Bolivia, Paraguay, southern Brazil and northern Argentina (Piersma et al., 1996). The migration south is probably non-stop and adults depart before juveniles. Some individuals fly over Hudson Bay in Canada and the region of the Great Lakes, and then cross the Atlantic heading south (van Gils et al., 2016d). Its main wintering area is on the coast of the La Plata River in the eastern Pampas in Argentina, adjacent to the large lagoon complexes in Uruguay and RS in Brazil. The migration north starts between February and March and is through the central region of South America, across the Gulf of Mexico and central USA and Canada, before reaching the coast of the Arctic in April-May (Lanctot et al., 2010). In Brazil, there are records between September and April for AC, RO, PA northern Pantanal (MT), and for RJ, SP, PR, SC and RS in (WikiAves, 2016; MPEG; MZUSP).

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.
