Pre-fledged Common Loon, Gavia immer, on an acidic lake dies with food bolus in escophagus
Bibliographic record
Abstract
Alvo, Robert, and Douglas Campbell.2000.Pre-fledged Common Loon, Gavia immer, on an acidic lake dies with food bolus in esophagus.Canadian Field-Naturalist 114(4): 700-702.A moribund prefledged Common Loon (Gavia immer) with a bulge in its throat was collected from acidic Silvester Lake.It died soon afterwards.Dissection of the bird revealed that the bulge was a food bolus containing Yellow Perch (Perca flavescens), dragonfly larvae (Somatochlora cingulata and Aeschna sp.), crayfish (Cambarus robustus) and whirligig beetles (Dineutus sp.).We suggest this bird may have swallowed a large fish that punctured the esophagus on its way to the proventriculus, causing peristalsis to cease.Food subsequently swallowed could not move beyond the esophagus, thus forming the bolus.The loon may have swallowed the large fish because food of suitable size for a bird of that size was in short supply due to the lake's acidity.

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.
