Abstract

fetched live from OpenAlex

We report autumn and winter breeding records for the American Robin (Turdus migratorius). We located a nest on the campus of the University of Columbia at Missouri, USA, active 12 to 15 October 1999. This late nesting record prompted us to consult the Cornell Lab of Ornithology’s Nest Record Program and Bird Studies Canada’s Project NestWatch. Of the 11 113 American Robin nest records in Cornell’s database, 15 were active in September and three were active later than September. Of the over 23 000 nest records available from Bird Studies Canada one was active in September and one in October. All four of the latest nests contained nestlings and were active on 3 October 1964 in Massachusetts, 13 October 1932 in Manitoba, 18 November 1964 in West Virginia, and 8 January 1966 in Ohio. Eight of the ten nests monitored until outcome could be determined fledged young successfully.

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.

Not 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.
