First Confirmed Nestings of Red-necked Grebein York Region, Ontario
Bibliographic record
Abstract
On 1 June 2019, the first recorded breeding by Red-necked Grebe (Podiceps grisgena) in York Region, Ontario, was established when a nest with one egg was found at the Moody Drive storm - water pond in the City of Vaughan. Although this nest was unsuccessful, a pair returned in 2020 and made another six unsuccessful nesting attempts. Also in 2020, another pair was found at the New Enterprise stormwater pond in Vaughan; they too made multiple unsuccessful nesting attempts. Both sites were reoccupied in 2021, and this time the pair at Moody Drive produced one young. In all three years, another pair of birds was also detected at Phillips Lake in Richmond Hill, also in York Region, but nesting was not confirmed. These events, following the first confirmed nesting record at a sewage lagoon in Durham Region (just east of Toronto) in 2018, involved a novel nesting habitat for this species, and perhaps a move towards usage of inland sites in southern Ontario, as opposed to sites along the Lake Ontario shore.

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.
