Diet of<i>Calidris maritima</i>(Purple Sandpiper) during the Winter in Nova Scotia, Canada
Bibliographic record
Abstract
Calidris maritima (Purple Sandpiper) is a shorebird found along northern coasts of Europe and eastern North America during the winter. While its winter diet is well known in Europe, the only North American study examining diet included 5 individuals and suggested a narrow diet focused on Littorina spp. (periwinkles). We examined the diet of Purple Sandpipers wintering at several sites in Nova Scotia, Canada, during 2013, and found that the birds consumed a broad variety of items, though principally marine invertebrates, dominated by periwinkles and Mytilus edulis (Blue Mussel), but also many arthropods. Our study confirms the importance of mollusks in the diet of this species and also indicates that Purple Sandpipers in North America have a similar winter diet to those studied in Europe.

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.
