INDICATOR: ROCKWOOD, MICHIGAN CHRISTMAS BIRD COUNT– OVERWINTERING BIRD COUNT FLUCTUATIONS Background
Bibliographic record
Abstract
The first Christmas Bird Count (CBC) was held in 1900. Since then, this early winter bird census has grown to nearly 2,000 individual counts across the Western Hemisphere, with over 50,000 participants (Dunn et al. 2005). CBCs tally all birds located within a 24.1 km (15 mile) diameter circle on a single day in early winter around Christmas; dates have now been set during the period December 14th through January 5th. The National Audubon Society (NAS) sponsors the CBC program and has a central repository for the results. The results are published in a quarterly magazine and are also available online (Audubon 2005). One of these 2,000 nationwide CBCs is centered in Rockwood, Michigan (42E03’35”N, 83E14’15”W) (Figure 1). It covers parts of Wayne and Monroe counties in Michigan and Essex County in Ontario. Approximate boundaries are Sibley Road (north), Amherstburg, Ontario (east), DTE Energy’s Fermi 2 Power Plant near Estral Beach (south) and Carleton (west). The Rockwood CBC was founded in 1974. The first year was considered a test

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.
