Food habits of the racer (Coluber constrictor mormon) in the northern part of its range
Bibliographic record
Abstract
Dietary habits of the racer, Coluber constrictor mormon, were studied based on stomach and faecal contents from 26 road-killed specimens and 297 live animals collected in the field during 1992-1994 in southern British Columbia, Canada. Thirty percent of the specimens examined contained gut contents. Coluber constrictor mormon feeds mainly on insects (91% of prey; Acrididae > Gryllidae > Tettigoniidae > Gryllacrididae) and occasionally rodents (7.5% of prey), as well as frogs and snakes (both < 1%). There were proportionally more vertebrates in the diets during the early part of the season (April - May). Diet was related to individual attributes, such as size or sex of the snake. Thus, larger individuals - primarily females - were more likely to feed on vertebrates, although insects were not absent from the diet of larger individuals. Diet composition (mammals vs. insects only) did not depend upon the method of sampling snakes. This study adds to the growing number of dietary studies on Coluber constrictor that continue to provide insights into the evolutionary ecology of this widespread but poorly-known species.

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.
