Abstract
The encyclopedic Birds of Saskatchewan (BofSk) 1 , published in 2019, compiled all historic and contemporary information on birds of the province reported over a 200-year period, up to 31 December 2016.Following this, new records and information for more than 27 species of birds were presented by Philip Taylor to update and clarify changes in their status in the province, to 31 December 2021. 2 This article includes important records of 23 species of birds encountered in Saskatchewan to 31 December 2022, in order of discovery.Detailed information updates the status of the following birds: one new species for Saskatchewan (Costa's Hummingbird); one hypothetical species confirmed and upgraded to accidental (Ivory Gull); four accidentals (Northern Pygmy-Owl, Hooded Warbler [two records], Green-tailed Towhee, Eurasian Tree Sparrow [two records]); and five stragglers (Red-bellied Woodpecker, Scissor-tailed Flycatcher, Wood Thrush, Pine Warbler, Summer Tanager).No birds were added to the provincial list of hypothetical species.The Saskatchewan Breeding Bird Atlas project ended as of December 2021.As a result, some notable records with evidence of successful breeding or territorial behaviour are discussed (Trumpeter Swan, Black-necked Stilt, Eastern Whip-poor-will, Western/ Cordilleran Flycatcher, Pacific Wren).Accepted COSEWIC changes to the status of birds in Saskatchewan current to summer 2022 are presented.Addenda and errata to the BofSk and Taylor are included.Changes to a bird's status require satisfactory documentation that has been carefully verified by a number of experienced birders.This follows the principles used in the BofSk and The RecordsTundra Bean-Goose (Anser serrirostris): an update.Remarkably, a bean-goose believed to be the same individual seen in Regina in the winter of 2019-20 was photographed at several different localities in eastern North America during its following, second and third, autumn and spring migrations in North America: "based on the coloration of the bill, it is probably the same individual that visited Saskatchewan in winter 2019, Ontario [14 to 19 November 2020 'Nolan Quarry, Prescott and Russell' , in the company of medium sized Canada Geese] and Quebec in fall 2020 [8 November 2020 Gatineau, with Canada Geese], Pennsylvania in winter 2020-2021 [17 December 2020 to 2 May 2021, with medium sized Canada Geese], and New York in spring 2021" and southern Quebec [4 November to 5 December 2021, with Greater Snow Geese].3 The last sighting was of the bird photographed on 15 May 2022 at Cap Tourmente National Wildlife Area, Quebec (with Greater Snow Geese).Dates and goose associations sourced on eBird and Cornell's Macaulay Library of photographs.Eastern Whip-poor-will (Antrostomus vociferus): two records.I learned of a previously unreported whip-poor-will from Jan Lake on the evenings of 28, 29, and 30 June 2017.Recordings of the calling bird were made by Leanne Loran, allowing PS Taylor to confirm the identification.Status: possible extension of summer (and breeding?)range.This location is at least 100 km north of previous records for the species around Cumberland House, which is believed to be part of the core range in the province.1 Remarks: photographs (Figure 1) were taken from the area the Loran family "thought the call might have come from.This area is a high, rocky ridge a bit north of the [cottage] development with birch, various evergreen trees, raspberry, blueberry, Labrador tea and juniper bushes, mosses and lichens" (J.Loran pers.comm.24 July 2022).Three calling birds were also encountered on the night of 12 July 2022 by Vicki St Germaine: "heard at 1245 and 0100" along "Highway 123, EB Campbell Dam to Km 50", "between NEW AND NOTABLE RECORDS

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.
