Whooping Cranes: The Road to Survival
Bibliographic record
Abstract
Whooping cranes are one of the best known of all endangered species and symbolize the struggle to maintain the vanishing creatures of this world. One scientist estimated that only 1400 whoopers survived by 1860. Their population continued to decline due to drainage of wetlands, conversion of grasslands to agriculture, and hunting until only 15 or 16 cranes survived the winter of 1941-42 in Texas. The present world population is about 450 wild and captive whooping cranes (2005). Only one self-sustaining population survives in the wild; these birds spend the winter at Aransas National Wildlife Refuge on the Texas coast and nest in Wood Buffalo National Park in the Northwest Territories of Canada, migrating 2,500 miles twice annually. There are approximately 200 birds in this flock. Over the last 50 years this population has increased an average of 4. 6 percent annually. If this rate continues, the population wintering along the Texas coast will total 400 birds by the year 2020.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
