Abstract

fetched live from OpenAlex

ABSTRACT Scavenging by seabirds at marine mammal carcasses on the open sea is a poorly documented phenomenon, especially among the smaller species of procellariiformes. During a pelagic survey in the Galápagos, I recorded at least fifty Elliot's storm‐petrels ( Oceanites gracilis ) foraging at a large piece of drifting blubber. Individuals pattered at the sea surface to pick up oil droplets, a foraging mode consistent with storm‐petrel ecology yet rarely documented in the context of mammal carcasses. Reports in other species emphasize consumption of blubber or tissue, but this observation suggests that small‐bodied seabirds may instead exploit the more metabolically efficient liquid fraction. This observation raises questions regarding the nutritional role played by opportunistic scavenging in storm‐petrels and the possible sensory cues facilitating such aggregations. Furthermore, it exemplifies the importance of natural history observations in documenting infrequent but ecologically significant interactions.

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.

Not 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.
