Abstract
For many species, we lack the basic information on distribution and abundance that is needed for conservation and management. The timberline Brewer's sparrow (Spizella breweri taverneri), a migratory songbird previously known to breed only in the Canadian and Alaskan Rockies, was recently discovered in abundance in high-elevation areas of Glacier National Park, Montana, USA. Because the southern limit of this subspecies' breeding range was unknown, we developed a GIS-based model to predict timberline sparrow habitat along the Rocky Mountain front south of Glacier National Park. We field-tested the model by surveying 40 predicted sites in the Lewis and Clark National Forest. We found suitable habitat at 20 of the 40 sites (50%), and timberline sparrows were present at 4 of these; we also found timberline sparrows at one site that was not predicted. The discovery of nesting birds at Jones Creek, in the Teton River drainage, extends the known breeding range of this subspecies 50 km south. Our study indicates that, even with relatively few initial data, GIS can be successfully used as a tool to guide surveys for rare species. However, there are inherent limitations in models built with restricted data, and species' distributions can be driven by factors not readily modelled in a GIS. Therefore, GIS models often must be treated as working hypotheses, to be tested and improved as additional data become available.

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
