Abstract
Risk factors for predation attempts by Peregrine Falcons (Falco peregrinus) were examined in Semipalmated Sandpipers (Calidris pusilla) during fall staging in the Bay of Fundy, Canada. Odds of attacks may be expected to vary with a host of factors such as time of day, time of year, spacing within groups and weather conditions. During the ebbing tide, 65 surprise attacks by falcons were recorded over 596 observation periods. Two factors emerged as risk factors for predation attempts by Peregrine Falcons on Semipalmated Sandpiper flocks during four consecutive fall staging periods. Falcons initiated attacks more often on denser flocks and later during the migratory stopover. Year, time of day and weather factors did not influence attack rate. These findings may reflect lower anti-predator vigilance in denser groups and the greater numbers of sandpipers available in the later stages of stopover. Fitness consequences of these attacks remain to be established.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
