Abstract

fetched live from OpenAlex

The Dusky Canada Goose (Branta canadensis occidentalis) once wintered regularly by the hundreds on the north coast of California, yet this fact has now vanished from much of the literature on the Canada Goose. In the 1930s James Moffitt found the subspecies was regular at two sites in Del Norte and Humboldt counties, but by the mid-1980s its numbers were much reduced and only occasional individuals were found thereafter. The retraction of the Dusky Canada Goose from the southern limit of its winter range parallels a rangewide population decline as well as surges in numbers of the recovering Aleutian Cackling Goose (B. hutchinsii leucopareia) and the proliferating Western Canada Goose (B. c. moffitti), possibly competitors.

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.
