Abstract
This report describes West Nile virus (WNV)-associated mortality in captive lesser scaup (Aythya affinis) ducklings that occurred in Saskatchewan, Canada, in July and August 2007. There were no clinical signs or gross necropsy findings suggestive of the cause of death; however, microscopic lesions were consistent with WNV infection, including nonsuppurative encephalitis and myocardial, pancreatic, and splenic necrosis. Necrosis of the thymus and thyroid was also observed in some birds, which has not previously been reported in association with WNV infection. Immunohistochemistry revealed WNV antigen in multiple tissues, including thymus and thyroid, and reverse transcription polymerase chain reaction resulted in the identification of WNV gene sequence in all of the ducklings that were tested. This outbreak is of interest because waterfowl (Anseriformes) are not thought to be particularly susceptible to WNV, and there is little information about WNV infection in prefledging birds. The apparent susceptibility of lesser scaup to WNV demonstrated in this study may have implications for declining lesser scaup populations in the wild.

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
