Foraging ecology of the Northern Goshawk in coastal British Columbia
Bibliographic record
Abstract
Effective wildlife conservation requires understanding diet composition and its consequences for population demography. I measured the diet of an at-risk population of Northern Goshawks (Accipiter gentilis) in southwestern British Columbia during two breeding seasons using pellets, prey remains, and nest cameras. I compared diet composition across two ecological zones and assessed the impact of dietary diversity and specialization on goshawk productivity. Goshawks consumed 33 different species but primarily consumed pine squirrels (Tamiascuirus spp.), which composed 14-61% of dietary biomass, depending on source. Diet composition differed slightly between the coastal and transition zones. I also conducted a pilot study of goshawk breeding season movement using GPS-UHF transmitters. Male goshawks used more space and travelled further from the nest than female goshawks. While I found no correlation between dietary diversity or specialization on pine squirrels and goshawk productivity, the abundance of this key prey species may affect goshawk productivity and space use.

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.
