Bird Migrations in the Central Flyway
Bibliographic record
Abstract
The Central Flyway has been recognized as a collective North-South migratory pathway centered on the North American Great Plains for nearly a century, but it has never been analyzed as the species that most closely follow it, or the major stopping points used by those species on their journeys between their northern breeding and southern wintering grounds. A total of 114 U.S. and 21 Canadian localities of special importance to birds migrat-ing within the Central Flyway are identified and described in de-tail. Judging from available regional, state and local information, nearly 400 species of 50 avian families regularly use the Central Flyway during their migrations. Nearly 90 Central Flyway spe-cies have wintering areas partly extending variably far into the Neotropic zoogeographic realm, and at least 50 of these winter entirely within the Neotropic realm. A few of these species un-dertake some of the longest known migrations of all birds, in ex-cess of 8.000 miles in each direction. Seven maps, 49 figures and over 100 literature citations are included. Wings over

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.
