Migratory Songbirds Transport Amblyomma longirostre and Amblyomma maculatum Ticks to Canada
Bibliographic record
Abstract
Birds transport ticks into Canada during northward spring migration, and some of these ticks are infected with tick-borne zoonotic pathogens. Some Amblyomma species harbour pathogens that cause debilitating diseases that can be fatal to humans, and domestic and wildlife animals. At least 65 Amblyomma spp. are indigenous in the Western Hemisphere, and approximately half bite humans. Amblyomma longirostre carries Rickettsia amblyommatis which causes spotted fever group rickettsiosis, a febrile disease in humans. Additionally, Amblyomma maculatum harbors and transmits Rickettsia parkeri, a spotted fever group rickettsiosis, and this tick bites humans. In the present study, we use two technologies to identify ticks. To confirm identification, we took microphotographs followed by DNA barcoding of the cytochrome c oxidase I gene. Based on molecular analysis, we confirmed that the two Amblyomma spp. were Amblyomma longirostre, a neotropical tick and Amblyomma maculatum, the Gulf Coast tick. Based on our tick-bird findings, we confirm that migratory songbirds transport Amblyomma ticks into Canada, and have the potential, either directly or indirectly, to transmit tick-borne zoonotic pathogens to humans.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
