Atlantic Flyway Review Fall 2021 Report
Bibliographic record
Abstract
Braddock Bay Bird Observatory is situated on the south shore of Lake Ontario midway between the eastern and western ends of the lake.The early successional site is dominated by fruiting woody plants -primarily dogwood, viburnum, and honeysuckle -along with a mixed wet forest until recently dominated by ash, and a field of grasses and goldenrod.The 36th consecutive year of fall migration monitoring at the Kaiser-Manitou Beach banding station was carried out for 65 days beginning 15 Aug and ending on 31 Oct 2021.Eight days were entirely lost to inclement weather and another five days to lack of a Bander In Charge.Three thousand four hundred eighty one birds of 79 species were banded, falling short of Fall 2020's total by 998 birds.Note that these numbers do not include our late July banding during the Yellow Warbler migration.There were no new species this season; our fall cumulative total stands at 128 species, with two additional hybrid forms and one intergrade form.Constant effort-mist netting was carried out using 32 nets.Included in the total were six doublehigh assemblies.A total of 9,549.75net hours of banding resulted in a capture rate of 36.5 birds per 100 net hours, compared with 40.8 birds per 100 net hours in Fall 2020 and 22.3 birds per 100 net hours in Fall 2019.We recaptured 870 individual birds a total of 1,358 times; 670 birds were captured after their initial banding day.Of these recaptures, 27 returned from a previous season, including one Blackpoll Warbler originally banded as an After-Hatching year bird in Fall 2020.Of the returning birds 59.3% had originally been banded as Hatch Year birds.The oldest of the returning birds was a Blue Jay in its 13 th year.There were no foreign recaps this season, but we received reports that four of our banded birds were found elsewhere.A Blue Jay banded on 16 May 2020 was found dead on 24 July 2021 in Brighton, ON.The remaining three re-encounters were not part of our passerine migration banding programs, but two especially deserve special note as they were originally banded two decades ago.A Redtailed Hawk banded 23 Apr 2001 was found dead on 1 Jun 2021 in Wayne County, NY, and a Bald Eagle banded 12 Apr 2002 was found dead on 4 Nov 2021 in Anderson County TN.The final reencounter was Northern Saw-whet Owl banded 22 Oct 2021, and recaptured and released on 6 Nov 2021 near Carsonville, PA.We deployed Lotek nanotags registered with the Motus Wildlife Tracking System on 20 Swainson's Thrushes, eight Hermit Thrushes, and 19 Blackpoll Warblers.sixty four percent of the tags were detected at other towers.Our local tower detected five Common Nighthawks, one Semipalmated Sandpiper, three Black Terns, four White-throated Sparrows, one Cerulean Warbler, and two Blackpoll Warblers tagged elsewhere.We were grateful to return to a more normal protocol; while we were still masked and distanced, we were back indoors.This season saw a return to more normal bird numbers as well, but the last half of October -often our busiest time -fizzled.We saw record-high numbers of Veery and Tennessee Warbler, and Brown Thrasher tied its high count.Cedar Waxwing was missing for the first time since 1989.

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.
