Harvest Distribution and Derivation of Atlantic Flyway Canada Geese
Bibliographic record
Abstract
Abstract Harvest management of Canada geese Branta canadensis is complicated by the fact that temperate- and subarctic-breeding geese occur in many of the same areas during fall and winter hunting seasons. These populations cannot readily be distinguished, thereby complicating efforts to estimate population-specific harvest and evaluate harvest strategies. In the Atlantic Flyway, annual banding and population monitoring programs are in place for subarctic-breeding (North Atlantic Population, Southern James Bay Population, and Atlantic Population) and temperate-breeding (Atlantic Flyway Resident Population [AFRP]) Canada geese. We used a combination of direct band recoveries and estimated population sizes to determine the distribution and derivation of the harvest of those four populations during the 2004–2005 through 2008–2009 hunting seasons. Most AFRP geese were harvested during the special September season (42%) and regular season (54%) and were primarily taken in the state or province in which they were banded. Nearly all of the special season harvest was AFRP birds: 98% during September seasons and 89% during late seasons. The regular season harvest in Atlantic Flyway states was also primarily AFRP geese (62%), followed in importance by the Atlantic Population (33%). In contrast, harvest in eastern Canada consisted mainly of subarctic geese (42% Atlantic Population, 17% North Atlantic Population, and 6% Southern James Bay Population), with temperate-breeding geese making up the rest. Spring and summer harvest was difficult to characterize because band reporting rates for subsistence hunters are poorly understood; consequently, we were unable to determine the magnitude of subsistence harvest definitively. A better understanding of subsistence hunting is needed because this activity may account for a substantial proportion of the total harvest of subarctic populations. Our results indicate that special September and late seasons in the United States were highly effective in targeting AFRP geese without significantly increasing harvest of subarctic populations. However, it is evident that AFRP geese still are not being harvested at levels high enough to reduce their numbers to the breeding population goal of 700,000.

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.
