Abstract
Hybridization between Mourning and MacGillivray's Warblers.--From6 June to 31 July 1963 I surveyed the distribution of the Mourning Warbler, Oporornis philadelphia, and MacGillivray's Warbler, O. tolmiei, in the foothill region of southwestern Alberta.The objective of this survey was to determine if a zone of contact or overlap of these two species occurs in this region, and, if so, whether or not hybridization occurs.Bent (U.S. Natl.Mus., Bull.203, 1953, pp.531-540) states that in Alberta the breeding range of the Mourning Warbler probably extends west to Grande Prairie, Glenevis, Camrose, and Nevis, while that of the MacGillivray's Warbler probably reaches east to Lesser Slave Lake and Edmonton (Figure 1), suggesting that range contact or overlap occurs in this region.My survey was confined to an area from the latitude of Edmonton on the north to the Sheep River south of Calgary on the south, and from a line through Stettler and Drumheller on the east to the Jasper-Banff Parks region on the west.Within these boundaries I drove roads passing through forest, brushland, or riparian forest and checked suitable habitat for the presence of singing males.

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.
