Autumn Marine Bird Populations in Queen Charlotte Strait and Adjacent Waters: a Candidate for IBA/KBA Status
Bibliographic record
Abstract
Systematic transect surveys of marine birds in eastern Queen Charlotte Strait and the western part of Johnstone Strait, British Columbia, Canada, were made between mid-August and mid-October 2020–2022. All birds within 100-m transect strips were counted and numbers corrected for detectability. Extrapolating within five regions of differing ecological characteristics and seabird densities, our results indicate that the study area supported 1% or more of the North American populations of Pigeon Guillemot Cepphus columba, Marbled Murrelet Brachyramphus marmoratus, California Gull Larus californicus, Glaucous-winged Gull L. glaucescens, Iceland Gull L. glaucoides, and Short-billed Gull L. brachyrhynchos. Our estimation of gull species in our study area would have been even higher if gulls in flight had been included in our survey. Furthermore, maximum estimates of Common Murre Uria aalge exceed the total population breeding in British Columbia. Only Pigeon Guillemot, Marbled Murrelet, and Glaucous-winged Gull breed in Queen Charlotte Strait, and only Marbled Murrelet is considered to be “at risk.” However, based on current criteria, it seems that the area would be a prime candidate for nomination as an International Union for Conservation of Nature (IUCN) Key Biodiversity Area.

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.
