Reproductive Success of Peregrine Falcons and Other Raptors at Wager Bay and Melville Peninsula Northwest Territories
Bibliographic record
Abstract
The Wager Bay area in northeastern Keewatin was surveyed for nests of raptorial birds during late July and August in 1976 and 1977, and the southwestern part of Melville Peninsula was also surveyed in August 1977.These surveys established Wager Bay and Melville Peninsula as the most productive nesting areas known for the endangered Peregrine Falcon (Falco peregrinus tundrius).More Peregrine Falcon sites producing young were located at Wager Bay than are known to exist in any other area of the North American Arctic.The production of young Peregrine Falcons at Wager Bay in 1976 and 1977 exceeded that of any area surveyed during the 1975 North American Peregrine Falcon Survey.In 1976 we located 14 nest sites occupied by Peregrine Falcons, 5 sites occupied by Gyrfalcons (Falco rusticolus), i1 sites occupied by Roughlegged Hawks (Buteo lagopus), and 1 nest site of a Golden Eagle (Aquila chrysaetos).In 1977, 27 Peregrine Falcon sites, 5 Gyrfalcon sites, 2 Rough-legged Hawk sites, and 1 eagle site were located.In 1977, Peregrine Falcons reoccupied at least 54%, and possibly as many as 91%, of the nesting territories occupied in 1976.Of the 13 peregrine sites visited in 1976, 85% produced young; young/ occupied site averaged 2.08, and young/successful nest averaged 2.45.In 1977, 84% of the 22 visited sites produced young; young/occupied site averaged 2.21, and young/successful nest averaged 2.95.The Peregrine Falcon sites did not differ significantly between years in percent successful sites, young/occupied site, or young/successful nest.There was no correlation between the number of young Peregrine Falcons produced at nest sites in 1976 and the number produced at the same sites in 1977.The nests that had been visited in 1976 produced 2.16 young/successful nest in 1977, as compared with 3.3 young/successful nest among the nests not previously visited.This difference was significant.Fifteen occupied Peregrine Falcon sites were located on Melville Peninsula, at least 10 of which produced young.The average number of young/successful nest was 2.6.The Peregrine Falcon populations at Wager Bay and Melville Peninsula did not differ significantly in either number of young/successful nest or in mean distance between occupied sites.Both the Wager Bay and the Melville Peninsula Peregrine Falcon populations are considered to be undepleted populations.A total of 30 Peregrine Falcon chicks from 11 nests were banded at Wager Bay and 6 chicks from 3 nests on Melville Peninsula.One of the banded birds was later captured on North Padre Island, Texas.

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.
