BREEDING RECORDS OF THE SURFBIRD, WANDERING TATTLER, AMERICAN GOLDEN-PLOVER, AND UPLAND SANDPIPER IN THE SOUTHWEST YUKON TERRITORY
Bibliographic record
Abstract
Knowledge of the breeding behavior and habitat selection of arctic–alpine shorebirds is limited because of these species’ remote habitats, low population densities, and cryptic behavior. We report nests and other observations of definitive breeding of the Surfbird (Aphriza virgata), Wandering Tattler (Tringa incana), American Golden-Plover (Pluvialis dominica), and Upland Sandpiper (Bartramia longicauda) in the Ruby Range of the southwest Yukon between 2002 and 2007. In most years, there were at least two breeding pairs of the Surfbird, one of the Wandering Tattler, three of the American Golden-Plover, and one of the Upland Sandpiper at our alpine study site covering 9 km². These are the first confirmed breeding records of the Surfbird in the southern Yukon, and they mark the second and third Surfbird and third and fourth Wandering Tattler nests documented in Canada. Despite the lack of previous records for all species, particularly the Surfbird, their consistent recurrence at the site suggests they breed regularly in the region.

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.
