Abstract
The American Three-toed Woodpecker (Picoides dorsalis) is a beetle specialist that feeds primarily on phloem-boring insects that occur only in the inner bark and cambium of attacked trees; apparently it seldom feeds on sap from trees (Murphy and Lehnhausen 1998, Leonard 2001). In Quebec, Imbeau and Desrochers (2002) observed it to spend only 0.6–1.4% of its time feeding on sap from Black Spruce (Picea mariana) trees, and in northern Manitoba Villard (1994) found only one individual feeding on sap. Short (1974, 1982) reported that P. dorsalis presumably does not drill its own holes for sap but occasionally takes it from wells drilled by sapsuckers (Sphyrapicus spp.). Villard (1994) speculated that sap feeding is less well developed in the American Three-toed than it is in the European Three-toed Woodpecker (P. tridactylus) because the sap-feeding niche in North America is already taken by sapsuckers, a conclusion questioned by Imbeau and Desrochers (2002). I found no definitive published reports of P. dorsalis drilling and feeding from sap wells in birch trees (Betula spp.).

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
