Pine Warbler (Setophaga pinus Wilson): new record for the state of Durango, Mexico
Bibliographic record
Abstract
The Pine Warbler (Setophaga pinus) inhabits eastern North America, where it breeds in the northern USA and Canada, and winters in southeastern USA. In Mexico, the species is considered an irregular winter migrant in the states of Nuevo Leon and Tamaulipas. We report the first record of the Pine Warbler for the state of Durango, in the protected area of the Cañon de Fernandez State Park, municipality of Lerdo. On 8 January 2023 at 11:42 h, a Pine Warbler was observed perched on a cypress tree (Taxodium huegelii), located on the banks of the Nazas River. The bird was on a branch approximately two meters above the ground. This record expands the species’ winter distribution in Mexico. Observations like this are essential for confirming movements of species in time and space during migration, and for documenting changes in the distribution of migratory species.
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.

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.
