PREDATION ON ADULT LONG-TOED SALAMANDERS AND A NORTHERN RED-LEGGED FROG BY A BELTED KINGFISHER ON VANCOUVER ISLAND, BRITISH COLUMBIA: A REVIEW OF DEFENSIVE STRATEGY ADAPTATIONS
Bibliographic record
Abstract
A case of predation by a Belted Kingfisher (Megaceryle alcyon) on adult Long-toed Salamanders (Ambystoma macrodactylum) and a Northern Red-legged Frog (Rana aurora) is reported. This general note provides a description of the predation events with photographs of the amphibians being devoured. Additional photographs showing scars in long-toed salamanders are presented and considered in review of types of predatory attacks and defensive strategies. A literature review was completed to identify reported cases of predation on these two amphibian species. We discuss what is known about their anti-predator defensive strategies and what species are involved in the ecological and evolutionary dynamics at play. Traits exhibited by these amphibians are discussed as anti-predator adaptations that include warning colorations, defensive postures, tail dropping, crypsis, and glandular skin secretions that can be adhesive, unpalatable, or toxic. A potentially significant role of avian predators is considered in light of the evidence presented.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
