Abstract

fetched live from OpenAlex

We reviewed historical records, old and recent publications, eBird, and Christmas Bird Count data to assess the abundance and distribution of Blue-winged Teal (Spatula discors) in California from the late 1870s to 2020. In general, Blue-winged Teal populations have changed from being considered a rare transient and winter visitor that was believed to not breed in California, to occurring at predictable locations in the winter and spring and with breeding records in every non-mountainous region of the state. Some of that difference is likely due to more people looking and improved ability to tell female Cinnamon Teal (Spatula cyanoptera) from female Blue-winged Teal, but data from the Christmas Bird Count over the last 40 years and eBird over the last 10 years demonstrate that Blue-winged Teal populations have increased. Between 2016 and 2018, 11 Blue-winged Teal with transmitters attached during winter in West Sacramento migrated in the spring to a variety of locations including the San Joaquin Valley, Northeastern California, Oregon, Idaho, and Alberta.

Full frame distilled prediction

Teacher imitation

Not 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.
