Tree Swallow Banding Near Saskatoon, Saskatchewan
Bibliographic record
Abstract
efore the settlement of the nearly treeless plains of southern Saskatchewan (Houston and Bechard 1983), cavity nesting birds such as the Mountain Bluebird (Sialia currucoides) and Tree Swallow (Tachycineta bicolor) were uncommon because of the lack of nest sites.They depended on decayed stumps and in the case of the bluebird, crevices in clay cliffs.Settlement brought telephone poles and fence posts with holes dug by Northern Flickers (Colapres auratus), mail boxes, twine boxes on binders, and crevices in buildings.These made excellent nesting sites, resulting in increasing numbers of Mountain Bluebirds and Tree Swallows (Houston 1977).Unfortunately, House Sparrows (Passer domesticus), followed in the 1940s by European Starlings ISturnus vulgaris), also increased in number, and gradually usurped most of the sites suitable for Mountain Bluebirds.The lack of nest sites, and the resultant decrease in bluebird populations, motivated Dr. Jack Lane of Brandon, Manitoba, and his Junior Birders, to build and set out nest boxes, each with an entrance hole 1.5 inches in diameter, too small to admit a starling.Observing Lane's success, Lorne Scott of Figure 1.Map of Prairie Bluebird Trail from Denholm, Glaslyn

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
