Population studies of Marbled Murrelets(Brachyramphus manners) in British Columbia
Bibliographic record
Abstract
We describe a novel approach to the study of a population of forest nesting seabirds (Marbled Mandel& Brachynnmphus marmora) which arc thought to be declining as a result of various potential threats to their emironment. This is the first research on this species which makes wide use of individually marked birds. It was made possible through the development of two capture techniques; (I) a floating mist net system which can be used in narrow coastal inlets close to where the birds breed and (2) using dip nets at night These techniques not only led to the marking of more than 1000 birds for a population based study, but allowed the collection of blood samples for physiological examination of breeding status in the absence of a large sample of birds at nests. We provide the First evidence of breeding area philopatry in this species. We also document the first longevity record for the species. Using a newly developed sexing technique based\t nology which could have wide application for other seabird studies, we found a large excess of males in our marked population. This probably reflects a differential tendency of males to be captured and may reflect a greater tendency of males to fly into the woods.

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.
