Apparent Survival of Adult Thayer's and Glaucous Gulls Nesting Sympatrically in the Canadian High Arctic
Bibliographic record
Abstract
We estimated apparent survival of 33 adult Thayer's Gulls Larus thayeri and 21 adult Glaucous Gulls Larus hyperboreus nesting sympatrically at a small colony on St. Helena Island, Nunavut, in Canada's high Arctic, using five consecutive years (2003–2007) of capture-mark-resight data. Resighting probabilities were high in all years for both species (0.97). Mean survival for Thayer's (0.81 ± 0.05) was low, but for Glaucous Gulls (0.86 ± 0.05) was comparable to estimates of survival reported for large gulls elsewhere. Both species showed high annual variation in survival, with one year each of noticeably lower survival, suggesting that some factors acting on survival may have differed between species and could reflect different species' exposure to natural or anthropogenic stressors. Our findings contribute to the limited demographic information on these polar gulls, and provide a basis for future comparisons should they be affected by changes in their polar environments.

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.
