Migratory Bird HuntingActivity and Harvestfor the 2010 and 2011Hunting Seasons- July 2012
Bibliographic record
Abstract
National surveys of migratory bird hunters were conducted during the 2010 and 2011 hunting seasons. Hunters of the following types of migratory birds were surveyed: waterfowl (family Anatidae), doves (mourning [Zenaida macroura] and white-winged [Z. asiatica]), bandtailed pigeon (Patagioenas fasciata), American woodcock (Scolopax minor), Wilson’s snipe (Gallinago delicata), American coot (Fulica americana), gallinules (Common gallinule [Gallinula galeata] and purple gallinule [Pophyrio martinica]), and rails (king rail [Rallus elegans], clapper rail [R. longirostris], Virginia rail [R. limicola], and sora [Coturnicops noveboracensis]). About 1.1 million waterfowl hunters harvested 14,796,700 (±4%) ducks and 3,169,900 (±5%) geese in 2010, and almost 1.2 million waterfowl hunters harvested 15,880,900 (±6%) ducks and 2,868,500 (±5%) geese in 2011. Mallard (Anas platyrhynchos), green-winged teal (A. crecca), gadwall (A. strepera), wood duck (Aix sponsa), and blue-winged/cinnamon teal (Anas discors), were the 5 most-harvested duck species in the U.S., and Canada goose (Branta canadensis) was the predominant goose species in the goose harvest. About 959,900 dove hunters harvested 17,230,400 (±5%) mourning doves in 2010 and 955,700 hunters harvested 16,580,900 ± 5% in 2011. Woodcock hunters numbered about 138,300 in 2010 and 113,800 in 2011, and harvested 332,900 (±11%) birds in 2010 and 308,700 (±16%) birds in 2011. About 37,500 people hunted snipe in 2010 and 32,700 in 2011, and they harvested 118,200 (±37%) and 136,300 (±49%) snipe in 2010 and 2011, respectively. Coot hunters (about 50,500 in 2010 and 46,200 in 2011) harvested 302,600 (±50%) coots in 2010 and 416,600 (±36%) in 2011. Gallinule hunters (about 15,000 in 2010 and 2,200 in 2011) harvested13,700 (±87%) gallinules in 2010 and 7,600 (±100%) in 2011. About 17,000 rail hunters harvested 27,100 (±57%) rails in 2009 and 3,300 rail hunters harvested 14,300 (±50%) rails in 2011.

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.
