Abstract
We organized annual expeditions to Rio Grande in Argentinian Tierra del Fuego from 2000 to 2004 to census, capture and band Red Knots Calidris canutus after their arrival on the southern migration from Arctic breeding grounds. The population declined from about 6,000 birds in 2000 to 4,000 in 2004. A total of 2,214 knots were banded, of which 1,787 were adults, 287 immatures and only 140 juveniles. Of 312 retraps, 88 had been banded previously at Rio Grande and the remainder were from localities in South America and Delaware Bay, USA. Average mass of the adults in the 2004 sample was significantly lower than in all other years (p < 0.0028), consistent with the fact that they had arrived three weeks later arrival at Rio Grande that year. Additionally, in both adults and immatures, average mass in 2002 was significantly lower than in 2000–2001 or 2003. Late arrival of adults in 2004 delayed wing moult and the intensity of body moult relative to other years. Studies of pathogens and parasites, feather isotopes and sex-specific survival are underway to try to elucidate possible additional causes of the severe and continuing population decline in the rufa population of the Red Knot. consistent with the fact that they had arrived three weeks later arrival at Rio Grande that year. Additionally, in both adults and immatures, average mass in 2002 was significantly lower than in 2000–2001 or 2003. Late arrival of adults in 2004 delayed wing moult and the intensity of body moult relative to other years.

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
