First Nest Records of the Pectoral Sandpiper (Calidris Melanotos) for Manitoba
Bibliographic record
Abstract
The Pectoral Sandpiper (Calidris melanotos) has long been considered an uncommon migrant in Manitoba and a transient in spring and fall at Churchill.To help document its timeline and history in Manitoba, and Churchill in particular, the following notations would apply.In 1934, Taverner and Sutton referred to this species at Churchill as "A transient, more common in autumn than in spring" 1 and they offered no suggestion that this species had ever nested in Manitoba.In 1955, Mowat and Lawrie gave one spring record for Churchill and suggested that this species was rare in that area and in locations to the north such as Chesterfield Inlet (Igluligaarjuk). 2 In 1970, Jehl and Smith stated that "Pectoral Sandpipers are uncommon at Churchill" in spring and more common in fall. 3As well, they stated that "We have no evidence that Pectoral Sandpipers nest anywhere in the region."In 1975, Cooke et al. referred to the Pectoral Sandpiper as a rare summer visitor on Cape Churchill. 4n 1983, Lane and Chartier showed this species as irregular in spring and more common in fall, with no suggestion of breeding at Churchill. 5n 1986, Godfrey gives the breeding range as being along the coast of Yukon and Northwest Territories, Banks Island, and Melville Island,

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.
