APPARENT HYBRID RUBY-THROATED × RUFOUS HUMMINGBIRDS IN WESTERN CANADA
Bibliographic record
Abstract
We present six observations, including photographs, of at least four individual hummingbirds from alberta and British columbia that we have identified as hybrids between the ruby-throated (Archilochus colubris) and rufous (Selasphorus rufus) hummingbirds, a hybrid combination currently poorly documented in the literature. Diagnostic features include the shapes of the primaries, the colors and relative lengths of the rectrices, and the gorget in the males. this hybrid combination adds to an already long list of hybrids between sympatric hummingbirds, many between species ascribed to different genera, as in this example. Field identification of hybrid hummingbirds, especially of females and immatures, can be very challenging, and many individuals are likely overlooked. one hybrid we report from alberta was at first mistaken for an extralimital Broad-tailed hummingbird (Selasphorus platycercus). We encourage observers to document and report potential hybrid hummingbirds to further our understanding of hybridization in this family.

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; a candidate call from one teacher head, not a consensus.
