Abstract
Chimney Swift (Chaetura pelagica): on 18 July 2017, Ron Jensen photographed an active Chimney Swift nest containing two young chicks at a farm near Zenon Park.The nest was located inside a wooden ventilation shaft within a barn, which rose into a cupola extending above the roof peak, providing access for the swifts to enter and leave the chimney-like structure.The eyes of both chicks were still shut, and pin feathers were starting to erupt on their backs and wings.In addition, a nest with two eggs, which had fallen from the wooden wall surface to the floor of the cupola, was recovered by Jensen on 18 July and donated to the Royal Saskatchewan Museum (collection's accession number RSKM_ BIRD_A-10484) (fide Ryan Fisher, Curator of Vertebrate Zoology, RSM, Regina).When this second nest was occupied is unknown: it was a failed attempt in either 2017 or a previous year.Status: only the third confirmed nesting location in the province and the first site found occupied for more than one year.Chimney Swifts are a solitary breeder with only one pair occupying a nesting site.6Remarks: this was the same location where Chimney Swifts were observed during the 2014 breeding season. 1 The 2017 photos suggested the young swifts were probably close to 7-8 days of age on 18 July; swift chicks open their eyes around 14 days of age.7 With this information as a starting point, we can extrapolate forward and back to estimate key dates in the breeding cycle for the swift nest near Zenon Park in 2017.Data collected on breeding swifts at St. Adolphe, Manitoba in 2014 to 2022 by Stewart and Stewart 8 provide us with a valuable chronological template.Calculations for the Chimney Swifts nesting cycle in 2017: egg laying likely took place about 22-23 June (using an incubation period of 17 days); hatching occurred about 9-10 July (based on the estimated age of the two swift chicks in the nest); fledging happened around 6-7 August (about 28 days after hatching); and the swift's final departure, both adults and chicks, was expected around 18-19 August (using the median departure date).Chimney Swifts arrive in southern Manitoba in the last week of May and start nest building starts almost immediately.Fall departure seems less predictable, varying between years as weather and availability of food fluctuates.Unfortunately, many older buildings with chimneys used as nest sites are being lost, and artificial nesting towers built to replace them have had limited success attracting swifts for roosting or nesting.6,9 2018 Whooping Crane (Grus americana): in autumn 2018, remarkable concentrations of Whooping Cranes were reported staging near Marcelin.As their numbers were apparently peaking, Guy and Sandra Wapple, Dale Booth, and Philip Taylor observed 152 Whooping Cranes, including seven rusty plumaged juveniles, in one harvested field on 11 October 2018,

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.
